Comment 9 for bug 366708

You guys,

what's the state of this one? What's STILL happening SINCE JAUNTY is that if i don't kill pulse right before starting playback, it will not work and just throw tons of "D: protocol-native.c: Requesting rewind due to end of underrun." errors. Same results when stopping and resuming playback.

I noticed that this only happens after pulse suspends the output (whatever that means...). If i (re-)start playback before pulse suspends my playback (usb) outputs, it will happily play back with just a few (1-4) lines of "...underrun." and no audible glitches whatsoever. Notice that this only affects my USB sound card (E-MU 0202USB).

So next i'll look into this suspending thing and what it means...

Output of "pulseaudio -vv" with hundreds of "Requesting rewind..." at the end removed:
