Hi all,
Could anyone make T61P's ICH8 sound controller to work properly?
Here's lspci |grep -i audio:
Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
Running linux-2.6.24 stable. If there's a know bug, I could try to dig
more on it and get more info.
Attached is my .config and dmesg output

ooh, a fellow t61p owner. How's suspend and resume working?

It works for me. http://userweb.kernel.org/~akpm/config-t61p.txt

If it's still busted please cc the "SOUND" developers (from ./MAINTAINERS)
on the reply, thanks.

Well it sort-of works. I started kde (fc8 install) and ran
play /usr/share/sounds/KDE_Close_Window.wav
and a prompt appeared titled "Error - artsmessage" with content "Sound
server fatal error: cpu overload, aborting".
After OKing that, the `play' command still works.
What could cause such a thing??

No idea yet. Does this happen after the kernel update, i.e. a
regression?

I'm also a T61p owner, and for me suspend is working. I'm using Linux
2.6.24 (32 bit version) and the newest driver from NVidia (yes, I know I
should be using the opensource driver, but it didn't work when I got my
laptop).
I haven't got hibernation working yet, but I haven't yet tried without
the NVidia module loaded (and as suspend works, hibernation isn't that
important for me).

This is actually fixed by upgrading to the newest version of the BIOS.
I'm currently running version 7LETA7WW (2.07), and haven't seen the
problem since I upgraded.

32-bit kernel? hm.
I use the xorg X11 driver. It's slow but that's OK.

suspend-to-disk works for me but suspend-to-ram fails in various different
ways depending on which kernel I'm running.

Interesting. Maybe that'll change suspend-to-ram behaviour as well.

Good that there's a lot of people using T61p, it's a good machine.
About suspend/hibernate I didn't try yet cuz I'm using a crytofs due
to work needs :-p ehehehe
I'll upgrade my BIOS and try again the crappy sound.
BTW, I'm using T61p Type 6458 Model DE9.

I have just bought X61s, and it seems to have the very same soundcard as
your T61p does:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
Subsystem: Lenovo Lenovo Thinkpad T61
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at fe220000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [50] Power Management version 2
Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
Capabilities: [70] Express Unknown type IRQ 0
Capabilities: [100] Virtual Channel
Capabilities: [130] Unknown (5)
The sound also doesn't work with 2.6.24 (tried modprobing the
snd-hda-intel with 'model=thinkpad', didn't make any difference). The
mixer settings seem to be correct, but there is no sound.
Two strange things in alsamixer:
- it is possible to change volume of the "PCM" toggle, but it is missing
the possibility to mute/unmute (the box with "MM"/"OO" simply isn't
there)
- the "Headphone" toggle has "OO" as it is unmuted, but there is no
possibility to change its volume, the volume box is completely missing
Takashi, if you need any other information which would help resolving
this, please let me know.
Thanks,

Hmm.. sound works just fine for me on my X61s (model #7668-CTO)
running 2.6.24.
I do have this private patch applied --- maybe it makes a difference
for you? I don't think it should make a difference, but....

commit c9001b03378048cad0f5c4f87dbb97fff1f80c51
Author: Theodore Ts'o <[email protected]>

hda_intel suspend latency: shorten codec read
not sleeping for every codec read/write but doing a short udelay and
a conditional reschedule has cut suspend+resume latency by about 1
second on my T60.
The patch also fixes the unexpected codec-connection errors that
happen more often in the new power-save mode:

These are intentional. There is no proper widgets (in HD-audio term,
corresponding to registers) to behave for these purposes.
On 2.6.25, you have additional "Master" volume and switch so that
these won't matter much, I hope.
> Takashi, if you need any other information which would help resolving

First, make sure that you unmuted the hardware volume / mute via
laptop keyboards.
If everything looks OK ("PCM" adjusted, "Headphone" and "Speaker"
unmuted) but still it doesn't work, it can be a driver problem.
If you set CONFIG_SND_HDA_POWER_SAVE, try to undefine it.
Or, try Ingo's patch Ted suggested. (To be noted, this couldn't get
in to the mainline because this causes problems on other devices.
2.6.24-git already inclues this patch but with some workarounds.)

I have also seen sound working flawlessly on another X61s. Maybe they
changed some chipset revisions on the fly, or whatever.
What does lspci -v show for your soundcard please?

I will give it a try, thanks.

Hmm, after flashing the newest BIOS update, everything seems to work now.
Felipe, that is probably your case too.

Thanks. As I have already written elsewhere in this thread, the problem
went away after I updated the BIOS to the latest version. So it was Lenovo
who was to blame, and I was just unlucky enough to hit the series with
broken BIOS.

BIOS upgraded, now the sound works on consoles (beeps) but not even
alsaplayer can play sounds.
I'll keep trying.
In any case, I have other issues: Serial port is really laggy (on Dock
of course), even if I use a usb-serial converter, still laggy (laptop
or dock).
USB is taking ages to enumerate.
If anyone has any clue about these... please shoot me :-p

I spent days getting it to work. I'm not an expert and don't know if made
any poor decisions, I tested suspend to ram in a bunch of configurations and
finally got it to work consistently. I think I have to restart the network
after resume, but I'm okay with that. Some things that may be of interest:
2.6.18-53.1.4.e15.centos.plus with native nvidia drivers
in /etc/grub.conf:
kernel /vmlinuz-2.6.18-53.1.4.el5.centos.plus ro agp=off
root=/dev/VolGroup00/LogVol00 rhgb quiet
in /ext/X11/xorg.conf:
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
EndSection
Section "Screen"

suspend to ram is working perfectly here:
s2ram -f -a 3
suspend to disk is perfect just issuing:
s2disk
;-)
PS: Stupid laptop, it works differently for everybody in this list :-p

Hello,
I have T61 and have no problem with sound. No sound problem could arise from
hw mute that is controlled via volume buttons. Volume mute does just mute (*no
unmute*!), buttons volume up/down unmutes volume.
There is bar "Speaker" in alsa mixer, must not be muted.
