Modified:
   trunk/README
   trunk/code/client/snd_openal.c
Log:
- I accidentally committed patch by slacker from (#4915) in r1916. Patch adds input device selection support
- Add check for ALC_ENUMERATE_ALL_EXT before using ALC_ALL_DEVICES_SPECIFIER in device enumeration
- Patch readme for new cvars by Zack Middleton
