I've seen this error too. As you mentioned, it only seems to happen between 
certain applications.

envy24 uses hardware mixing for playing multiple audio streams at the same 
time. I don't know if vchans is even used -- you might try if disabling 
vchans makes any difference.

Unfortunately I can't help to solve the problem but I can do some testing if 
someone comes up with a patch.
