--- Comment #7 from YAOMTC emailofchris@gmail.com --- Okay, after a restart, the problem came back, and I realized... I had downloaded it, but forgot to actually build and install it. Oops, I don't even know how I thought I had installed it... Anyway, I installed it for real just now (wow that took ages to compile), and... the problem persists.
So that wasn't the solution after all. I must have forgotten to restart PulseAudio after updating, and was still using the old version...
So, the problem is NOT solved with wine-multimedia. Sorry, my mistake.
