sound problems on debian

["Arvind Marathe" <arvind@mbu.iisc.ernet.in>]

Hi all,
i just cannot get sound working on my machine. I have installed alsa and
run alsaconf. But if i try 'speaker-test' or 'cat /dev/urandom >
/dev/audio', i just don't get any sound. I have attached several outputs
below so that somebody else might be able to figure out what is wrong.
Anything i need to do?

thanks and regards,
Arvind
