Quake2Forge sound
=================
Quake2Forge supports several sound output APIs.
To set your sound output driver, set the snddriver cvar, like so:
quake2 +set snddriver oss
The currently supported list of drivers are:
oss -- OSS from Linux 2.4 and earlier, and some BSDs
alsa -- ALSA 0.9 from Linux 2.6 onwards
ao -- libao audio output library
Each driver uses the snddevice cvar in different ways:
oss uses the device node for the sound card, e.g. /dev/dsp
alsa uses the pcm name, e.g. default or plughw:0,0
ao uses the name of the backend, e.g. oss or alsa09
e.g.:
quake2 +set snddriver oss +set snddevice /dev/dsp
quake2 +set snddriver alsa +set snddevice default
quake2 +set snddriver ao +set snddevice oss
Unexpected behaviour can usually be attributed to a snddevice setting from
a previous snddriver.
The sound driver can be changed at run time from within the console by
setting the two cvars above and calling 'snd_restart':
]set snddriver ao
]set snddevice oss
]snd_restart
