Posted: Sun Jan 14, 2007 8:36 pm Post subject: alsa and oss issues [SOLVED]

Hello,

I can't get oss work using alsa.

I first installed alsa by emerging alsa-driver and alsa-oss with the "oss" use flag set, but I got "invalid module format" messages on alsasound start for all the oss modules. Installing alsa without oss support just worked fine.

So, I decided to compile alsa module into the kernel, I unmerged alsa-driver and alsa-oss and manually deleted the /lib/modules/{uname -r}/alsa-driver folder.

And now I got these error messages :

Code:

[ root:/lib/modules ]$ /etc/init.d/alsasound start [2007-01-14 15:11:06]

with the dmesg output :

I know the issue is described on the gentoo alsa guide (http://www.gentoo.org/doc/en/alsa-guide.xml#doc_chap3) but trying to do wat they say didn't solved it.

I tried to completely uninstall alsa from my system (both in kernel and alsa-driver modules), cleaning modules.conf, but I still had these messages on boot :

Code:

ALSA /var/tmp/portage/alsa-driver-1.0.14_rc1/work/alsa-driver-1.0.14rc1/pci/ac97/ac97_codec.c:2041: AC'97 0 does not respond - RESET
ALSA /var/tmp/portage/alsa-driver-1.0.14_rc1/work/alsa-driver-1.0.14rc1/pci/ac97/ac97_codec.c:2050: AC'97 0 access is not valid [0x0], removing mixer.
VIA 82xx Audio: probe of 0000:00:07.5 failed with error -5

I tried to find a solution on the web, and every time people solved the problem and says "ok, I found the solution, everything was mixed up and I can't explain".

It seems a person here had the same problem as me : http://forums.kororaa.org/viewtopic.php?t=271&postdays=0&postorder=asc&start=0&sid=072e30afb2f89357a8d26ad7b9fc1df9

So, two (linked) questions :

1) does anyone knows how the hell you can totally uninstall alsa-driver ?
2) does someone see what's my problem with oss in alsa ?

Thank you a lot for your help.

yeah, that's exatly what I did, but that's what I get now :

Code:

[ root:/lib/modules ]$ modprobe snd-via82xx
WARNING: Error inserting soundcore (/lib/modules/2.6.18-suspend2-r1/kernel/sound/soundcore.ko): Invalid module format

So I think some alsa-driver things are still hidden somewhere.

Ok, I fixed half of the problem by doing a little "make mrproper" in /usr/src/linux ...

.. but, oss still isn't working :

Code:

$ /etc/init.d/alsasound start
* Loading ALSA modules ...
* Loading: snd-card-0 ... [ ok ]
* Loading: snd-pcm-oss ...

* Restoring Mixer Levels ...

with always this very strange dmesg error :

Code:

CPI: PCI Interrupt 0000:00:07.5[C] -> Link [LNKC] -> GSI 5 (level, low) -> IRQ 5
PCI: Setting latency timer of device 0000:00:07.5 to 64

I don't understand why it try to lad something from /var/tmp/portage/alsa-driver : frist of all this directory no longer exists, and alsa-driver had been unmerged ...

use kernel drivers instead alsa-driver package. it's a better choice!

Okm I finnaly got it working !

This [censored] alsa-driver package does'nt uninstal well, it let a repository "/lib/modules/{uname -r}/misc" with its compiled module, and apparently these modules are choosen in place of those compiled with the kernel.

So if you experience the same problem as me, juste

Code:

$ rm -rf /lib/modules/{uname -r}/misc
$ cd /usr/src/linux
$ make && make modules_install

it should work.

Its not a big deal if your running kernel is compiled to have its config accessible online in /proc/config.gz
