snd_dsp_optimization 1 (optimizes DSP effects, same purpose as above)
snd_obstruction_enable 1 (it muffles sounds that are obstructed by physical objects, extra realism)
snd_mix_soundchar_enabled 1 (Turns sound char on for mixing)
snd_async_fullyasync 0 (Sound doesn't play until data arrives)
snd_mixahead 0.05 (The amount of seconds the mixing operates ahead of time, the less the more instant the sounds come)
snd_mix_async 1 (Enables usage of above)
snd_legacy_surround 1 (When set to 1, it uses the old way of producing surround sound, this reduces channel exclusivity slightly, and sounds more natural)
dsp_enhance_stereo 1 (Part of the DSP effects, as it describes, enhances stereo effects. But I personally don't notice any difference.
