i/o can be problem with sound


Just a question concerning sound output.

I have sound playing cd and that's all.

Can it be any trouble with system don't finding sound output ??

Alsa is ok ( i can hear a cd without any trouble and sound is fine ).

All mixers are 100 % so i don't believe there is any problem is this area.

I cannot hear any sound even as root, so i think there is no chmod trouble.

arts is off ( i had troubles with it and don't get any sound when on anyway)

The problem is where to advise linux i'm using Alsa ?? ( when arts is out i cannot select any other output )... when is on and i select Alsa i get in troubles ( but don't get any sound ).

I cannot hear any wav sound ( even linux ones ) and games are silent too.

Any idea ??

Having a CD play doesn't necessarily mean your sound drivers are working - AFAIK, most CD-ROM drives have a cable that connects them directly to the sound card in order to play cd audio without the need for software intervention.

So unfortunately, it probably is a problem with ALSA and/or arts.

I'm in the same boat - having trouble getting sound up and running.

Do you get any error messages at any point? If not, it must be either a muted or 0 volumed channel... or else everything's REALLY messed.

Post any errors you get, as well as the output of lsmod.
trying alsaconf couldn't hurt, either.

If you see something wrong let me know.

I have no error message and all mixers are at 100%.

But Arts is off by now ( was not doing much good ).

Via82xx is detected ok ( i changed modules to match Alsa requirements ).

Let me know if something new is coming to you.
