(Please don't top post)
The first possibility that I can think of is that this application
doesn't support ALSA and your OSS emulation isn't working.
This leads to a complicated question. Is ALSA built into your Kernel or
installed as modules? If installed it is modules, they should be in:
If modules check for the directory:
which should contain a few files (mine has 2).
If installed as modules, you must have the correct configuration
information in /etc/modules.conf. Presuming that you have only one
sound card, this should be:
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
If ALSA is built into the Kernal, the most likely problem would be that
something was missing from the Kernal.
