I am sorry, I should've specified -- its not as if there is silence, I hear some weird buzzing noises on the cat command.
Oh, that's VERY different. You are getting sound, just not the sound you want to get. The "cat" approach is not a good way to try to play music files, not even .wav files ... the exact output you'll get is a bit unpredictable ... but "weird buzzing noises" are a definite possibility, even from a working system.
See the next set of comments below.
Other things are that trying to play mp3 files via xmms gives a dialog box asking me to check: That the soundcard is configured alright The correct output plugin is selected No other program is accessing the soundcard
What userid are you using to run xmms? It needs either to be root or some userid that is a member of group "audio", based on this part of your response (deleted above):
# ls -lF /dev/dsp crw-rw---- 1 root audio 14, 3 Mar 14 2002 /dev/dsp
If it isn't, you'll get the message from xmms that you report (it's a bit misleading, but it really is the one you get ... I had this exact problem on a new system last week), since xmms is running under a userid that does not have permission to write to /dev/dsp . Since (I think) your system has you as the only real user, you can select the easy fix of
chmod 666 /dev/dsp
to avoid this problem. Or try running (say) mpg123 as root. Or add your preferred userid to the audio group (edit /etc/group, then do a brand new login using the userid) and try xmms again.
I started with the first suggestion -- the output plugin selected is the OSS driver, and I don't think there are any other applications trying to access the soundcard.
