My sound card doesn't play any sound.

Play program returns the following message:

sox: Sound card appears to only support 2 channels. Overriding format

but it doesn't exit at once. It plays the song but I can't hear anything.

Audio Player doesn't return any message as well. It plays the song but I
can't hear anything as well.

I have the speakers pluged into the proper socket and Sound Mixer isn't
turned off.

I have RH9 with standard kernel 2.4.20-8. I didn't configure or remove
any functionality from the kernel.
sndconfig and Sound Detection from KDE claims that finds the following card:
Model: 82801BA/BAM AC'97 Audio
Module: i810_audio

The following is what system reports:
