I did that too.

It works for me with .wav and DVD files.

I never tried playing sound as user before but when I checked I had the 
same problem, with both 'play' (sox) and mplayer.
play *.wav:  Can't open output file '/dev/dsp':  Permission denied
ls -l /dev/dsp shows that user has read and execute permission.

mplayer -ao oss *.wav:  Can't open audio device /dev/dsp:  Permission 
denied.

mplayer is also r-x for user.

(If I don't specify -ao oss on the command line:  Unable to open audio. 
No available audio device.  oss must not be on a list of available 
devices, unlike svga for video).

Can you get mplayer to play oss sound by putting that in 
/root/.mplayer/config (as ao=oss)?

drvmidi (for awe32 midi playing) as user 'cannot open sequencer device'.
It works fine for root.  So yes, this is a systemic problem with sound.

I did not see anything obvious in /root that would affect sound except 
.aumixrc, and copying that to /home/user did not help.

Why do you want to be user instead of root?

I can't even get it to install without a segfault except on one computer.
