From b4d7cbeb34a1a430ab145c0b446eac4f3795f4ca Mon Sep 17 00:00:00 2001
From: molivier <molivier@d7cf8633-e32d-0410-b094-e92efae38249>
Date: Wed, 8 Jun 2005 06:06:44 +0000
Subject: [PATCH] Changed default sound module for linux to ALSA. Modified
 makefiles to allow people to choose the sound module easily at compile time
 (ex: "make DP_SOUND_API=OSS release" compiles release binaries with OSS sound
 output). Available sound modules are: NULL, OSS, ALSA, BSD, WIN, and
 COREAUDIO (not functional yet).
