Commercial-OSS-on-Solaris patch... --ryan. Date: Sun, 14 Aug 2005 23:06:40 -0500 From: Shawn Walker <binarycrusader@gmail.com> To: sdl@libsdl.org 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: http://icculus.org/~eviltypeguy/SDL_audiodev.patch I'm sure there may be a better way to do it, but the above patch is what worked for me. --=20 Shawn Walker, Software and Systems Analyst binarycrusader@gmail.com - http://binarycrusader.blogspot.com/
