That's not the fault of our audio driver, it is because of linux doing
bad things with i/o scheduling. For whatever reason as soon as a wine
blocks on i/o all other threads get cpu starved. This is not a wine bug,
but a linux bug.
I'm not in favor for yet another half supported sound system, I would
rather have our own sound systems working better. Can't you just use
forwarding from JACK or something?
