Hi,
I have switched from 2.2.17 to 2.4.2 and now the sound is no longer working
on my Toshiba Tecra 8000 Notebook. In 2.2.17 I used the following modules:
mpu401
ad1848
opl3sa2 io=0x538 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0
opl3 io=0x388
This was working perfectly. I was able to control all mixer settings, the
microphone was working and xmms was able to play nice sounds.
Then I have switched to kernel 2.4.2 and now the kernel says:
2001-03-29 10:02:50.054774500 {kern|info} kernel: ad1848/cs4248 codec driver
Copyright (C) by Hannu Savolainen 1993-1996
2001-03-29 10:02:50.070692500 {kern|notice} kernel: opl3sa2: No cards found
2001-03-29 10:02:50.070703500 {kern|notice} kernel: opl3sa2: 0 PnP card(s)
found.
I have nothing changed in the BIOS of the Notebook. I have set up a dual boot
so I can switch back to kernel 2.2.17 and the sound is still working there.
I was able to enable the 8 Bit Soundblaster emulation of the Tecra with these
modules:
uart401
sb io=0x220 irq=5 dma=0 mpu_io=0x330
opl3 io=0x388
But this is very ugly. I can't control all mixer settings, the microphone is
not working and xmms is playing scratching noise (mpg123 is working)
What happened to the kernel? How can I use the opl3sa2 driver in kernel 2.4?

Add 'isapnp=0' to the end of the options in your modules.conf.
I *believe* this is fixed in a later kernel (2.4.3pre or 2.4.2ac).

If I am doing this, I can't even load the module and I get the following
message in syslog:
2001-03-29 18:13:14.184156500 {kern|err} kernel: opl3sa2: Control I/O port
0x0 not free
What is that "control i/o port"? Is this normally 0x100? What is the module
parameter to specify this io port? The documentation only mentions "io",
"mpu_io" and "mss_io" but I have specified these parameters already:
modprobe opl3sa2 io=0x538 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0
isapnp=0

I believe it can be, but I remember it usually being something
like 0x370 or so.

It would be what you put in the io= parameter. 0x538 does *not* look
right.

These are the sound-settings in the BIOS:
WSS I/O: 0x530
SBPro I/O: 0x220
Synth I/O: 0x388
IRQ: 5
WSS (Play) DMA: 1
WSS (Rec) DMA & SBPro-DMA: 0
Control I/O: 0x538
MPU I/O: 0x330
The BIOS does not let me modify the I/O settings for Synth, Control and MPU.
And as I said: The opl3sa2 module was working perfectly in kernel 2.2.17 with
these settings. And I wonder why the message in syslog says "0x0", no matter
what I/O address I have specified with the io= parameter.

Hm, OK, then never mind. :) I don't have an opl3sa2 here to test
how well the current driver works.

I have the feeling that there is going something wrong with the parameters. I
modified the opl3sa2 driver and manually set the hw_config->io_base variable
to 0x538 and now THIS part of the sound card initialization is working. But
now it says that there is an I/O conflict with MSS. Maybe this parameter is
also 0x0 and not 0x530 as I specified with the mss_io parameter... I will
investigate further...

Hm... I found this somewhere near line 920 in opl3sa2.c. I am not a kernel
hacker and this is first time I took a look into a kernel source code but
this first "if" statement is not looking right to me. The initialization of
the cfg[card] struct is what I need to be executed, but it is never executed
because the variable "io" is never -1. I have removed the io == -1 condition
from the first if-statement and now the driver is working. But it's still not
the same quality as the one in kernel 2.2.17: I have no access to the mixer
settings "bass" and "treble". But better than nothing and better than the
8Bit-Soundblaster emulation. I hope this is working better in the next
release.
if(!isapnp && io == -1 ) {
if(io == -1 || irq == -1 || dma == -1 ||
dma2 == -1 || mss_io == -1) {
printk(KERN_ERR
"opl3sa2: io, mss_io, irq, dma, [...]
return -EINVAL;
}
cfg[card].io_base = io;
cfg[card].irq = 0;
cfg[card].dma = -1;
cfg[card].dma2 = -1;
[....]

The same problem exists for the Toshiba 4000CDS. I think it is because
the OPL3SA2 in these machines is not using PNP.
Probably the support for non-PNP chips broke during the recent update of
the driver (2.4.0 works perfectly).

Tried to post this from another account yesterday but it
seemed to go awol :)
I had a similar problem when I moved from 2.4.1 to 2.4.2
with a tecra 8000.
The solution was to use 2.4.2ac20 which appears to solve
the problem. The opl3 code changed between kernel
versions.No BIOS or modules.conf were harmed....
Rgds,
Alan
