<pre>From your log:
( 0.118| 0.000) D: [pulseaudio] alsa-mixer.c: Checking for playback on
Digital Stereo (HDMI) (hdmi-stereo)
( 0.118| 0.000) D: [pulseaudio] alsa-util.c: Trying hdmi:2 with
SND_PCM_NO_AUTO_FORMAT ...
( 53.036| 0.011) D: [pulseaudio] alsa-util.c: Managed to open hdmi:2
( 53.036| 0.000) D: [pulseaudio] alsa-util.c: Maximum hw buffer size is 371
ms
( 53.041| 0.004) D: [pulseaudio] alsa-util.c: Set buffer size first (to 3528
samples), period size second (to 441 samples).
It takes 52 seconds to just open the ALSA device "hdmi:2". I assume this is
what you mean with "the sound system hangs". And it is most definitely a kernel
problem, nothing we can do about that in PulseAudio.</pre>
