I have now tried the issue with the latest nightly builds of Takashi + 
PA 0.9.13.
I started kaffeine and after a while I paused the playback:


I: protocol-native.c: Requested tlength=250,00 ms, minreq=20,00 ms
I: protocol-native.c: Final latency 460,00 ms = 210,00 ms + 2*20,00 ms + 
210,00 ms
I: module-suspend-on-idle.c: Sink 
alsa_output.pci_10de_26c_sound_card_0_alsa_playback_0 idle for too long, 
suspending ...
I: module-alsa-sink.c: Device suspended...

Waited for a couple of seconds and clicked play in Kaffeine:

I: module-alsa-sink.c: Trying resume...
I: module-alsa-sink.c: Resumed successfully...
I: module-alsa-sink.c: Starting playback.
I: module-alsa-sink.c: Underrun!
N: module-alsa-sink.c: Increasing wakeup watermark to 40,00 ms

And the playback doesn't even continue. Sometimes it continues with a 
lot of glitching, sometimes it hangs.

Any other suggestions?
