fyi I've opened [1] on the rhythmbox freezes issue.  I've got a few backtraces 
up though I'm unsure how useful they are in this situation with streaming media.

In about 5 tries I got rhythmbox to freeze after vt switch, the latest comment 
has the backtrace of that specifically.  pactl does not show SUSPENDED as a flag 
on any sink (I have two sound cards, though only one is being used at that 
time), and the acls seem to have access for my user (that is attached to the bug).
