Hello,

I'm now running latest kernel 3.19 from vivid:

Linux dali 3.19.0-16-generic #16-Ubuntu SMP Thu Apr 30 16:09:58 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux

And this issue is still present for me. I grabbed debug pulseaudio logs
again, see attachment. Audio was completely lost when messages such as
this started to show up in logs:
