Subject: [SDL] [PATCH] Audio Detection Bug
When using the OSS commercial drivers under Solaris 10, SDL will not
properly initialise OSS audio support (dsp) if /dev/sound exists.
Under Solaris (as far as I understand) /dev/sound is provided as a
means of accessing a BSD style audio device, not the OSS device.
SDL assumes that if /dev/sound exists, then it must be running on a
Linux 2.4 system and should make the dsp device path /dev/sound/dsp.
This is wrong. When using the OSS commercial drivers under Solaris,
the dsp device is always referenced as /dev/dsp normally.
My proposed fix is to stat the dsp device in /dev/sound to make sure
it exists, before assuming /dev/sound/dsp as the audio device:

I'm sure there may be a better way to do it, but the above patch is
what worked for me.
