Some applications keeps accessing /dev/dsp.
You can run the following command to see what application is opening
/dev/dsp:
fuser /dev/dsp*
Read: man fuser.
Run also:
lsof -p ###
Where ### es the process number of an application
Read: man lsof

When I use play, it plays the soundfile, but afterward, I can't open any programs that would use my soundcard (some open but say it can't find the device or that the device is in use). When I run "ps aux" there's no indication of play being there. However, when I run play and it gets to the end of the soundfile, I hear what sounds like an amp clip, and I get this:

Is there something in that line (or the rest of the program) that I should change to get it to work with my hdsp? I have an onboard nVidia soundcard that works with play just fine, and aplay works fine with both cards. Is it a problem in the play program, or maybe the alsa hdsp driver I'm using? Another thing I noticed is that when I use play, the signal is being sent to all the channels on the hdspmixer, whereas when I use aplay, it sends it just to the first two. What gives?
