Thanks. So the most disturbing in the first log is:

( 262.115| 0.000) D: [alsa-sink] alsa-sink.c: Waking up in 43.01ms (system clock).
( 270.521| 8.405) E: [alsa-sink] alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 1822684 bytes (10332 ms).

This was probably where it started to be completely broken.

So - what happened during this 8 seconds, that was running at a higher priority than PulseAudio? PulseAudio should have woken up in 43 ms, but it was 8 seconds until it actually woke up - and then PulseAudio is quite bad at recovering from that situation unfortunately.
Did you notice any sudden 8 second hang of your computer?
