Could you elaborate? The mic bias level could be changed via the pin
control value. Usually, it's set as VREF 80%.

This is a known bug in alsa-lib mixer abstraction. No kernel issue.

You can find *.INI file that contains the default pin configuration
in Windows. This might be useful in the case BIOS is broken but
Windows does a black magic.

Anyway, please run alsa-info.sh with --no-upload option and show the
generated file here. It contains the codec information and mixer
setup.
http://hg.alsa-project.org/alsa/raw-file/tip/alsa-info.sh

Also, you can adjust the pin setting on the fly via hda-verb utility
below:
http://ftp.suse.com/pub/people/tiwai/misc/hda-verb-0.2.tar.bz2

Don't forget to build snd-hda-intel module with
CONFIG_SND_HDA_HWDEP=y to use this command.

Probably the same as

I am available to help, too. My card works quite well, modulo the mic
problem and a lower output than in Vista, and I'd love to see it solved.

FWIW, I'm seeing this problem as well (ALC268 too) on my Acer Aspire
5720Z laptop.

Dupes of this bug report are NOT hard to find:

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3609
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3637
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3897 (reported by me)
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3930
...probably more

Please, if there's anything I can do to fix this, I will. I can apply
and test patches, no problem.

I'm attaching my own alsa-info.txt in case it helps.

Thanks.

When the recording->capture level is set to 0, the mic has no DC
offset as expected. Maxing the recording->capture level, the mic input
is saturated, in between, we see a linear connection.

That'll be these defaults stashed in the INF file [2]. Let me know if
it's not what you expected and I'll publish the complete INF file.

I'll give this a shot if I get time.

Looking at the datasheet and ALSA report, changing the front mic node
id also affects capturing from the (rear) mic input.

ftp://66.104.77.130/pc/audio/ALC883_DataSheet_1.3.pdf

We get the "hda_codec: Unknown model for ALC883, trying auto-probe
from BIOS..." kernel message, so we may need to tweak
pci/hda/patch_realtek.c. Also, I can reproduce the problem the with HD
and legacy front-panel audio settings in the BIOS. Do you know a way
to dump eg the pin configuration in windows or other useful state, so
I can compare with all the possible node ID configuration values?

Depends on the hardware implementation. But, usually, no, different
pin widgets are assigned for front and mic jacks.

Note that this is no error but information. The driver has preset
models for known devices and use the static configuration table for
such devices. For other devices, the driver just relies on BIOS
setup.

Sorry, no, I've not booted Windows over years :)

You can try to adjust VREF value of mic pins.
For example, the node 0x18 and 0x19 correspond to the rear and front
mics, respectively. Then run the following as root:

# ./hda-verb /dev/snd/hwC0D0 0x18 SET_PIN_WID 0x21

which will change the widget 0x18 (rear mic) to input-VREF 50%
(0x21). The original value is input-VREF 80% (0x24).

I find that a good way to examine the captured PCM is the following command:

$ arecord | od -t x1z -v

With the "Capture" and "Digital" controls both at 0 in alsamixer, this
outputs just a constant 0x80 byte. This seems natural.

With "Digital" at 0, changing "Capture" has no effect. However, with
"Capture" at 0 and these values for "Digital":

db gain -30 byte read 0x80
db gain -28 byte read 0x81
db gain -26 byte read 0x82
db gain -22 byte read 0x83
db gain -19 byte read 0x84
db gain -17 byte read 0x85
db gain -15 byte read 0x86
db gain -13 byte read 0x87
db gain -12 byte read 0x88
db gain -11 byte read 0x89
db gain -10 byte read 0x8a
db gain -9 byte read 0x8b
db gain -8 byte read 0x8d <-- up two here
db gain -7 byte read 0x8e
db gain -6 byte read 0x90
db gain -5 byte read 0x92
db gain -4 byte read 0x94
db gain -3 byte read 0x97
...
db gain 12 byte read 0xff
db gain 13 (and up) byte read 0x00 <-- seems to flip over or get capped

If I now change "Capture" to have dB gain 0 (35% in alsamixer), I get
this instead (for different values of "Digital"):

db gain -30 byte read 0x80
db gain -29 byte read 0x85
...
db gain -18 byte read 0x90
...
db gain -12 byte read 0xa0
...
db gain -6 byte read 0xc0
...
db gain -1 byte read 0xf2

So in fact, if both controls are at dB gain 0 (or one of them is
higher), the only byte I can read is 0x00.

I tried to do this for my card. For me, I need the 0x19 widget, which
is the internal mic:

Node 0x19 [Pin Complex] wcaps 0x40008b: Stereo Amp-In
Amp-In caps: ofs=0x00, nsteps=0x02, stepsize=0x4f, mute=0
Amp-In vals: [0x00 0x00]
Pincap 0x083724: IN Detect
Vref caps: HIZ 50 GRD 80 100
Pin Default 0x99a30941: [Fixed] Mic at Int ATAPI
Conn = ATAPI, Color = Unknown
DefAssociation = 0x4, Sequence = 0x1
Misc = NO_PRESENCE
Pin-ctls: 0x24: IN VREF_80
Unsolicited: tag=00, enabled=0

And I tried various values for the PinCtl. 0x20, 0x21, and 0x22, (0x24
was the default), but with no change in the input byte stream AT ALL!
And I double-checked, my input source is set to "Internal Mic". (Just
to be 100% sure, I tried all three input sources, but it was the same
for all. So no change in the input at all.)

Do you have any more tips that I can try out?

Also, I am just curious, is it possible to break the microphone (or
other physical components) by changing the voltage levels to
unsupported values, or is it safe to experiment freely? I read this in
the HDA specification:

"The VRefEn field encoding selects one of the possible states for the
VRef signal(s). If the value written to this control does not
correspond to a supported value as defined in the Pin Capabilities
parameter, the control must either retain the previous value or take
the value of 000, which will put the control in a Hi-Z state and
prevent damage to any attached components."

Thanks!

The "Digital Capture Volume" is the software attenuation/gain in
alsa-lib. Keep it in the middle corresponding to 0dB. Otherwise you
change the data digitally by the software. This control exists for
some devices that have only digital mics and no hardware analog
volume controls.

"Capture Volume" is the hardware recording level.

Did you get ANY input from the internal mic? If no, the pin mapping
might be wrong. That is, 0x19 isn't the internal mic.

There is no safe thing as long as you work as root :)

But, I've not heard any report that the wrong pin (at least VREF)
broke the whole circuit, though.

Thanks. I have Digital set to 0 dB now, and I am using only the Capture control.

Now I've tried the external mic, with only VERY limited success (see below).

> Did you get ANY input from the internal mic? If no, the pin mapping
> might be wrong. That is, 0x19 isn't the internal mic.

The external mic:

Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out
Amp-In caps: ofs=0x00, nsteps=0x02, stepsize=0x4f, mute=0
Amp-In vals: [0x00 0x00]
Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
Amp-Out vals: [0x80 0x80]
Pincap 0x083734: IN OUT Detect
Vref caps: HIZ 50 GRD 80 100
Pin Default 0x02a19840: [Jack] Mic at Ext Front
Conn = 1/8, Color = Pink
DefAssociation = 0x4, Sequence = 0x0
Pin-ctls: 0x24: IN VREF_80

So what I have done is this:

In alsamixer, Capture is set to 21 dB gain (Digital at 0 dB). This
will read mostly 0xa9 with alsarecord. If I try to sing a tone, this
value can change briefly between 0xa9 and 0xaa for as long as I sing,
such as this:

0631340 a9 a9 a9 a9 a9 a9 a9 a9 a9 aa a9 aa aa aa aa aa >................<
0631360 aa aa aa aa aa aa aa aa aa a9 a9 a9 a9 a9 a9 a9 >................<

...otherwise, it is at a constant 0xa9.

However, something interesting here happens when I change the voltage
level while recording. It seems that there is a short fluctuation (it
lasts only a fraction of a second) where the values change...:

If I change the PinCtl from 0x24 to 0x21, it seems that the data
values will change in this order (with many repetitions of each
value):
... 0xa9 0xb2 0xb1 0xb0 0xaf 0xae 0xad 0xac 0xab 0xaa 0xa9 ...

and then it is back at the constant 0xa9 value. If I change the PinCtl
from 0x21 to 0x24, the values will change in this order
... 0xa9 0xa0 0xa1 0xa2 0xa3 0xa4 0xa5 0xa6 0xa7 0xa8 0xa9 ...

So this seems to be the only difference between the internal and
external mic. I am no expert in this, but I guess the voltage change
will simply raise/lower the membrane of the microphone and the change
will be reflected in the values read back...?

But this at least assures me that the external mic pin configuration is correct.

The input volume is zero. Try to raise "Mic Boost" (if present)?

They're already all up.

Line In Boost = 100
Mic Boost = 100
Internal Mic Boost = 100

Right after changing all these to max, I've read the value from
card0/codec#0 again:

Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out
Amp-In caps: ofs=0x00, nsteps=0x02, stepsize=0x4f, mute=0
Amp-In vals: [0x00 0x00]

There doesn't seem to be any difference. Even when changing them all
to 0 in alsamixer, this output stays the same.

Sorry, I just discovered yet another "Mic Boost" control in the
playback section in alsamixer (the others were in the capture
section). Changing this now gives me:

Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out
Amp-In caps: ofs=0x00, nsteps=0x02, stepsize=0x4f, mute=0
Amp-In vals: [0x02 0x02]

Strange.

Weird. What happens if you execute the verb directly via hda-verb
program like below?
hda-verb /dev/snd/hwC0D0 0x18 SET_AMP 0x7002

It's a known bug of alsa-lib mixer abstraction layer.
Some controls appear on both playback and capture views although only
the value is changed only on playback mode.

So, don't worry, it's not your fault ;)

Yep, this has the same effect has changing the "Mic Boost" control in
the Playback section of alsamixer.

What I discovered now, though, is that I get a much wider range of
values from the external mic (so playback of the captured data
actually sounds correct). It actually works, but there is still a very
strong DC offset that seems dependent on the level of the "Capture"
control. This offset still makes it unusable for recording, since even
slightly louder noises will clip the samples.

It also seems that this control is reset each time I start Audacity
(even though the "Mic boost" level in alsamixer doesn't change). But I
guess this unrelated to the DC offset issue.

Changing the voltage level now (0x21, 0x22, 0x24, with Mic Boost at
0x02) doesn't change the DC offset, but has the same effect as before
(the values fluctuate, but eventually stabilize at the same level).

Thanks for the help.

Hmm, then it's all what I can guess right now.
There might be some vendor-specific settings I don't know of.

To be sure, try the following git tree (master branch), pull on
2.6.26:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

This contains the patches for the next kernel, and some of them are
related with Realtek codecs.

Maybe. I can readily dump the PCI config space of the Intel HD-audio
controller in Windows and list differences; the datasheet from Intel
allows us to decode the registers. Will this help us any? Of course,
we really need to dump the target behind the HD-bus, but that's
another matter...

I don't think it's an issue of PCI register but rather codec setups.
PCI registers cannot influence on an analog thing like DC offset.
So, we need to peek the HD-audio codec registers if really doing so.

Thanks, I've now tried it, but still it doesn't work.

At least the right model is detected, because this is my laptop:

hda_codec.c:2352: hda_codec: model 'acer' is selected for config
1025:11e (Acer Aspire 5720z)

I also applied this patch for some extra debug output (and teach me a
bit about how registers change in response to alsamixer changes):

..and in the log, I have this when modifying the "Capture" control:

hda_codec.c:157: write verb 00000300 parm 0000901a = 0

Now I consulted the HDA specification, and I find this surprising:

Verb 3h (set Amplifier Gain/Mute) has the following payload bits:

15 Set Output Amp
14 Set Input Amp

...but the payloads that I logged (a01a and 901a) would correspond to
bit 15 being set, which is the Output Amp!

Does that seem immediately obvious to you?

I will dig some more. Thanks for the help so far.

I applied this as well, just to make sure, and I tested again:

@@ -906,6 +908,9 @@ int snd_hda_codec_amp_update(struct hda_codec

..and yes, changing the "Capture" level does indeed set the Output bit
when modifying this control. Maybe there's something wrong with the
set-up of mixer or pin controls that makes ALSA think this is an
output stream?

Is there something strange here:

Pin Default 0x02a19840: [Jack] Mic at Ext Front

Node 0x19 [Pin Complex] wcaps 0x40008b: Stereo Amp-In

Pin Default 0x0281304e: [Jack] Line In at Ext Front

..or it certainly seems that all the inputs claim to have output
capability too. Maybe this is what is confusing ALSA?

I will try to change the Gain/Mute levels manually using hda-verb
using the Input bit instead of Output and see how it goes.

No.

Basically, the input/output amps mean the amp input to the widget
and the amp output from the widget, respectively. They don't mean
that the playback or capture stream direction. So, it's perfectly OK
if the amp is output for a capture stream.

One exception is the pin widget. In this case, the input amp means
the amp applied for the input signal from this pin, and the output amp
means the amp applied before sending to this pin. So, the
input/output actually corresponds to the stream direction. But, for
other widgets, the amp I/O is just a difference between before or
after.

Okay, yes. I now output the nid that is changing too, and you are
correct, it is not the pin widget, but this one:

Node 0x23 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
Amp-Out caps: ofs=0x0b, nsteps=0x1f, stepsize=0x05, mute=1
Amp-Out vals: [0x03 0x03]
Connection: 7
0x18 0x19 0x1a 0x1c 0x14 0x15 0x12*

I guess I will need to read up on what exactly an audio selector is
before attempting any more debugging.

Thank you for keeping up so far. I'll try to shut up now until I have
something more tangible to report :-)

Yes, I had tried this and it does not help, perhaps only changing the
magnitude of the sampled mic input.

Another smoking gun, is when changing certain mixer settings (both on
gnome-mixer and alsamixer), eg playback->front mic amplitude, moving
the slider up and down, the L/R linking seems to be almost randomly
unlinked and the other L/R channel jumps to a different value. When
re-linking the L/R channels, often, it'll unlink again and change both
value after reading back the change; mute can be erratic too.

Is there a good way to debug this also?

This seems: http://bugzilla.kernel.org/show_bug.cgi?id=10300

I do not think it's related, I had the mic problem *before* seeing this.
It's not fixed as 2.6.26-rc5, btw.

As the mic is working fine, but with this variable DC offset, it felt
like something needed tweaking in the mixer (summation) node. I
understand more about the node connectivity now, and found muting the
front mic mixer input and setting LR gain to 0 at mixer node 23h
addresses the issue:

(from page 42 at ftp://66.104.77.130/pc/audio/ALC883_DataSheet_1.3.pdf)

# ./hda-verb /dev/snd/hwC0D0 0x23 SET_AMP_GAIN_MUTE 0x7180

Vegard - your HD bus enumeration looks similar and I'd bet the vendor
followed the same Realtek application note, so can you give this a
shot too? If not, try mixer node 20h.

My motherboard (Asus P5E-VM HDMI) has front-panel HD-audio (selectable
as legacy in the BIOS) connectors, but I've never been able to get
them working, so left the cables disconnected...surely not a board
design issue, as default pin configuration wouldn't explain the
offset?

Thanks,
Daniel

Using your dumped config and
ftp://202.65.194.211/pc/audio/ALC268_DataSheet_1.3.pdf page 42, your
front mic pin complex is at node 19h; the mixers connecting to it are
at nodes 0Bh, 22h and 23h, all at the second input index, so one of
these should work:

# ./hda-verb /dev/snd/hwC0D0 0x0b SET_AMP_GAIN_MUTE 0x7280
# ./hda-verb /dev/snd/hwC0D0 0x22 SET_AMP_GAIN_MUTE 0x7280
# ./hda-verb /dev/snd/hwC0D0 0x23 SET_AMP_GAIN_MUTE 0x7280

On my ALC883, we need to mute the first input instead, thus 0x7180.
Can you see if the above helps you out?

Thanks,
Daniel

Thanks for helping out!

Unfortunately, none of these commands (with either 0x7180 or 0x7280)
seems to make any difference at all. (I tried various combinations,
with reloading the driver in-between to undo the trial attempts.)

I made a mistake - the second input is selected by 0x7180, as the
first is 0x7080...perhaps retry this with nodes 0Bh, 22h and 23h?

Failing that, these are the steps I'd try:
1. setup audio so as to reproduce input DC offset
2. start recording in audacity and observe DC offset
3. for each input of each mixer:
3.1 mute until you see the DC offset disappear

ie for ALC268, mixer input amps at nodes (# inputs): 0Eh(1) 0Fh(2)
10h(3) 18h(1) 19h(1) 1Ah(1)
ie:

# ./hda-verb /dev/snd/hwC0D0 0x0e SET_AMP_GAIN_MUTE 0x7080
# ./hda-verb /dev/snd/hwC0D0 0x0f SET_AMP_GAIN_MUTE 0x7080
# ./hda-verb /dev/snd/hwC0D0 0x0f SET_AMP_GAIN_MUTE 0x7180
# ./hda-verb /dev/snd/hwC0D0 0x10 SET_AMP_GAIN_MUTE 0x7080
# ./hda-verb /dev/snd/hwC0D0 0x10 SET_AMP_GAIN_MUTE 0x7180
# ./hda-verb /dev/snd/hwC0D0 0x10 SET_AMP_GAIN_MUTE 0x7280
# ./hda-verb /dev/snd/hwC0D0 0x18 SET_AMP_GAIN_MUTE 0x7080
# ./hda-verb /dev/snd/hwC0D0 0x19 SET_AMP_GAIN_MUTE 0x7080
# ./hda-verb /dev/snd/hwC0D0 0x1a SET_AMP_GAIN_MUTE 0x7080

Changes are real-time, so no need to restart anything. Once you've
found which mixer input amp and input index stops the DC offset, reset
the HD codec (eg reboot) and try just that one! I'm interested in
hearing if this finds the issue...

The only result was the muting of playback.

But thanks for the hints, I'll try to look for other combinations that
might help too. If you have other ideas too, I'll be happy to try them
out!

I tried all this, to no avail. At some point input stopped recording
sound, it has just offset, but I can't say which one was... if it's a
useful data, I can retry it.

And... I have almost never booted it, but I have a Vista installed in
this laptop. If you explain me how to do (in windows I am a dumb user) I
can try to search thing. What I know is that the sound in windows is
quite louder, and that recording works better. There is a button with
"offset correction" default on, if I remember correctly.

That'll be the software 'fix' the Realtek guys mentioned to Takashi.

It's clear the issue with the ALC268 is different than the ALC883
offset issue that I'm seeing, which seems to be a bug as ALSA isn't
muting the mixer inputs which aren't intended.

Hi Takashi,

I am still finding this recording +ve saturation on my ALC883 Intel
HDA sound device with 2.6.27-rc3 (ie ALSA 1.0.17 drivers) and ALSA
1.0.16-1 libraries on Ubuntu Intrepid.

The previous workaround still 'gets us out of jail':

# ./hda-verb /dev/snd/hwC0D0 0x23 SET_AMP_GAIN_MUTE 0x7180
nid = 0x23, verb = 0x300, param = 0x7180
value = 0x0

Note, we see this message "hda_codec: Unknown model for ALC883, trying
auto-probe from BIOS..." as before on this Asus P5E-VM HDMI
motherboard with current BIOS.

How can we improve the situation, as out the box, the front/rear mic
inputs are (still) useless?

Many thanks,
Daniel

Could you try the patch below? With this patch, unused connections
will be disabled. Let me know if it really works so that I can merge

There were a couple of issues: getting the mute logic right from
moving the assignment and increasing the number of inputs beyond the
11 required here to avoid the 'Too many connections' message and
fixing the last input being skipped.

With the updated patch, the problem is fully addressed; no resulting
DC offset, so recording quality is great. This seems logically safe
and a hopeful for 2.6.27-rc4...

The updated patch is against 2.6.27-rc3.

Thanks once again,
Daniel

Oh I should have more carefully checked.

Thanks. There is another problem in the current patch.
It should use snd_hda_codec_write() without caching. Otherwise
it breaks the suspend/resume.

The revised patch is below. Please test and report back if it works
so that I can push it to the upstream.

thanks,

Takashi

ALSA: hda - Fix capture source widgets on ALC codecs

On some Realtek codecs like ALC882 or ALC883, the capture source is
no mux but sum widget. We have to initialize all channels properly
for this type, otherwise noises may come in from the unused route.

The patch assures to mute unused routes, and unmute the currently
selected route.

This patch is first one you sent, except differing line numbers
(rediffed against 2.6.27-rc3?).

You could try attaching the patch to the mail too, to avoid the line
wrapping, silent whitespace conversion and any gmail/mailer 'hide
quoted text' mangling...

Thanks,
Daniel

Oops, I forgot to refresh it. Below is the right one.

On LKML, the patches should be inlined.
And, you can save a raw file even via gmail, too...

[PATCH] ALSA: hda - Fix capture source widgets on ALC codecs

On some Realtek codecs like ALC882 or ALC883, the capture source is
no mux but sum widget. We have to initialize all channels properly
for this type, otherwise noises may come in from the unused route.

The patch assures to mute unused routes, and unmute the currently
selected route.
