I have the same problem (for a similar reason, I'd like to play Starcraft 2 and listen to some music) and I'm glad that there already is a thread for this. But I don't really understand what you want to tell Lishy with the links. Sorry, I don't have the insight into the Linux systems yet and don't understand how the sound is managed. I googled a bit about this problem myself but had trouble understanding most of my results. Do you want to say that this is a known problem and hard to fix or that one should follow the "WineAndPulseaudio" guide? That one frightened me off a bit, because it states that it might break all but the most simple setups.
