[Bug 489210] Re: AC97 sound board does not work properly.

Wed Apr 28 12:54:13 UTC 2010

Hi!

It is not an issue anymore. I fixed the problem. But 
the problem was a little more complex.

It seems at that time some ALSA drivers lock the 
mixer or the audio input, but I didn't try enough 
to know what drivers exactly do this or what exactly 
is happening. 

I removed some drivers by hand, save the alsa configuration 
(using "alsactl store") then alsa began to work properly 
with pulseaudio. 

I don't know if it can happen now. To find this I have to play 
around with all the alsa drivers (what at this moment I don't 
have time to do). 

The script I did to remove the drivers that fixed the problem 
is this:

-------------------------------
#!/bin/sh
rmmod snd_cs4236
rmmod snd_hwdep
rmmod snd_wavefront
rmmod snd_cs4236
rmmod snd_hwdep
rmmod snd_mpu401
rmmod snd_mpu401_uart
rmmod snd_opl3_lib
rmmod snd_wss_lib
-------------------------------

What driver in particular cause the mixer or audio input/output 
to lock I have no idea. Perhaps the opl3_lib or wss_lib but I 
really don't know. 

Hope it help.

Thanks for the atention and sorry for not posting this info before.

Hugs!
Ric

Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .  Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag.  This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.  Please let us know your results.
