Hi,

There is no sound from my ac97. I've installed Kaffeine and it shows that it's playing a file but no sound comes out of the speakers. The speakers are connected fine and are not muted. The drivers all appear to be there. I'm on FC4. The problem looked like it was here:

Desc: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller
Driver: snd-via82xx
Device: None

However on a working system it gave me 'Device: None' as well but everything worked there.

I've tried:

artsd -F 10 -S 4096 -d -b 16 -s 5 -m artsmessage -c drkonqi -l 3

without the '-f' option but that did not print anything usefull to the screen.

Thanks,
Dev

What Kernel are you using?

From above his module list:

I have no idea what's wrong but on my Slackware based system, I have to run gmix in order to hear audio. Perhaps you need to do something similar? Run some kind of "mixer" app?

Peace...

Well the reason I was asking is because I know that some Slackware Kernel (dont remeber which one, all I know is that it's the one default in Slack 10.1) doesnt have support for AC97....

But when I was having thesame problem as you have I just updated my kernel using my slack cd...

Hi,

I tried using Kmix and changing settings but it didn't do anything (I've put the settings back). Are there utilities I could try to use to debug my sound? Something that would tell me where is it stopping and if I'm missing anything would be great. There's '/root/scsound.log' and other logs in '/var/log' but checking them, I can't see anything that would cause this type of problem.

Regards,
Dev
