Now for a > little backgroung and some more details. Try doing a fstat /dev/dsp0 when you get the "Device busy" message. If it doesn't list anything, fstat /dev/audio0 and /dev/dspW0, if you have that one; and any other sound devices, to see if there is really something locking the card. You should be able to get a complete list of your sound device names by doing ls -l /dev/dsp0 noting the major device number (the one before the comma), then doing something like this (replace "128," with the number you see, with the comma): ls -l /dev |grep "128," If any of those fstat commands show a process, that's probably the problem. Otherwise, I'm not sure what to suggest. Notice, btw, that I'm having you fstat /dev/dsp0, not /dev/dsp. /dev/dsp is a symlink to /dev/dsp0, and nothing will be holding that open. Also, if a fstat shows a process, the R/W column will tell you if it's trying to play sound (W) or record sound (R). One more idea below... > Just purchased the sound blaster 16 pci card.

Is this a problem? Is this true both when you do get sound and when you don't? That strikes me as odd...but so does the fact that your card is being recognized as something other than SoundBlaster. The PCM and SBC drivers say they support ESS-based cards also, but I note that there's an snd_ess.ko kernel module...wonder what that's for...
