Sound system looks OK but no sound from speaker
« on: June 28, 2008, 03:36:33 pm »

I've just installed VL on a ageing notebook (Gateway SOLO 2150).  I've used alsaconf to set up the sound card and all looks OK.  However when I try commands such as "play /usr/share/sounds/alsa/Noise.wav" no sound comes out of the speaker.  Ditto if I try to play a CD using xine.  I have checked that the sound is unmuted in using the "alsamixer" command.

some tech details:

Which version of Vector did you install?
if it's SOHO (KDE) Check and make sure the volume is turned up and not muted in the mixer.

if it's vl 5.9 Standard run alsamixer and check to make sure volumes set ok.

Its 5.9 (standard).  Yes - I have run alsamixer and the controls aren't muted. Also the volume is turned up.

Its a tough one this.

If I put headphones on I hear a "click" when the ALSA daemon starts.  Hmmmm.

The sound card has several posts of problems. Not many solutions

I noticed from lsmod that you have the AC97 modules loaded, which maybe
creating a conflict. So remove those and test again.

There was a post that some had luck changing from ALSA to OSS sound server.

Thanks.

I've tried downloading the closed source oss drivers.  Installed kernel-headers, kernel-source, gcc, make etc.  Get lots of errors and module won't build.  Also chewed up my alsa modules  :'(

Any other ideas?

I have been googling for a couple hours. No real
success. I found this might work:
