I'm using the kernel alsa drivers with the 2.6.15-suspend2-r6 kernel 
with alsa-lib 1.0.11_rc3 and alsa-headers 1.0.11_rc3.

This is where it's kinda weird.  If I use vo=alsa then the .wav files 
won't play at all.  If I use ao=arts, then they work, but skipping 
around, like fast forwarding or rewinding lags.  Like, I'll press the 
left or right button and then about a second later it will actually 
rewind or forward.  Before I migrated to the modular xorg, when I used 
the alsa driver it worked fine and it responded immediately when I 
skipped around.

I seem to get that error regardless of what I'm playing.  I can play 
some files, like mp3s with the ao=alsa and that message will still 
appear, but it plays anyway.

Also, if I do the 'lsof /dev/dsp' command as you suggested, it only goes 
to a newline and then just sits there.  It seems to do that for any file 
i use it on.  The man page for that program is like a mile long and I 
don't have time to read through it right now.  I'll read it later though.

Also, I don't know if it's worth mentioning or not, but the whole reason 
I upgraded to the modular xorg is because it was the only way I could 
get my mobile intel video card to work with the i810 driver and dri 
rendering.
