This is probably not closed yet. 105681 was closed because of previous underruns. This bug is about causing underruns. :(

Depending on the timing of when a FIFO underrun is detected, you get either this message or the one in 105681. I'm marking this as a duplicate because both have the same underlying cause, and the other triggers more. *** This bug has been marked as a duplicate of bug 105681 ***
