I've been struggling with this bug and pulling my hair out trying to fix it.
Sorry to hear that. Ideally it would just work without having to set environment variables. Can you give us a little more information? Specifically, what PulseAudio version are you using? What sound hardware do you have: built-in motherboard audio, USB audio device, something else? Can you get us a log demonstrating the problem with the channels from https://wiki.winehq.org/Sound?
