I have Mythbuntu installed on a Jetway J7F2 miniITX mobo. It used the Via 8372 audio chip and after booting works for several minutes.

Sound then craps out and requires a reboot to bring it back. You might occasionaly get the odd burst of corrupted staticy vaguely recognisable sound but VERY occasionaly. Restarting X has no effect.

There are no messages in dmesg, there are no relevant messages in /var/log/messages. You can open amixer and play with settings nothing complains about any problem, just no sound.

If I boot from the CD, mount the harddrive and play music that way it works for hours. Boot from HD and it dies adter several minutes. Playing video's causes the same problem, sound dies, same symptoms. Why should it work booted from CD but not from the install from the same CD?

I found a post on a similar, not the same, problem and followed intructions there on downloading and compiling the latest ALSA drivers which I think are 1.0.16. This made not one jot of difference.

I then did away with X and just tested from the from the command line, if I do "aplay test.wav" I get about 10 seconds of audio before it cuts out.

rmmod and modprobe on snd_via82xx brings the sound back. "speaker-test" plays for at least an hour which is as long as I've left it so far. aplay on my test.wav file kills it again in seconds.

I can repeat it at will. still no sign in dmesg or /var/log/messages that anything is amiss.

Can anybody suggest where I might look next?

Cheers

Pete

As soon as the sounds goes, have an X-term (command line) standing by and pipe dmesg off to a file, and then

sudo tail /var/log/messages > some_file_name_1
sudo tail /var/log/syslog > some_other_file_name_2

Any progress on this problem?

It seems that I have the same problem; and cannot solve it so far.

Thanks,

Zoilo.

In fact, I already entered a description at http://article.gmane.org/gmane.linux.alsa.user/30026.

TIA,

Zoilo.

No, no progress. Haven't had a chance to do anything with it. Someone on the ubuntu forum suggested trying the OSS driver which goes by the name of via82cxxx_audio which might be worth a go. When I get a minute I'll try and install it to se if it helps.

Was going to say that its nice to hear that someone else is having the same problem, but its not nice for you is it?!

Cheers
