I don't know your level but there is an interesting post here about what is Pulse Audio and sound in linux: But with your current error, it means the expected oss output doesn't even exist. Code: alsa-base alsa-utils libesd-alsa0 linux-sound-base libsdl1.2debian-oss libasound2-plugins libpt2.6.5-plugins pulseaudio pulseaudio-pluginsAs the default ouput sound for quake3 is not available or busy, instead of hacking or changing manually the sound settings, with the script we redirect the expected oss output to sdl.
