This is by far the hardest game to set up on Linux that I've encountered.
In the past, many people set this game up using ALSA, which resulted in distorted sound coming from the input and high delay. Some people figured out how to route it from JACK all the way to RS_ASIO, which produced much better results. I've used this information, created a guide and have been updating it regularly. It's pretty long, so it's published like this now:
TL/DR: there you go.
