f12 audio video issues

[Skunk Worx]

I am using a variety of closed source -- nvidia, gstreamer-ugly plugins, 
vlc etc. Sorry.

About 3 weeks ago I could play media of all types fine on f12. Some 
updates a couple of weeks ago have apparently caused a variety of 
clicks, pops and stutters in videos.

I see this popup in the movie player and it hangs :

pa_stream_writable_size() failed: Connection terminated

And this in the var log messages :

Jan  8 18:35:36 localhost kernel: ALSA sound/pci/hda/hda_intel.c:691: 
azx_get_response timeout, switching to polling mode: last cmd=0x018f000c
Jan  8 18:44:08 localhost pulseaudio[1490]: alsa-sink.c: ALSA woke us up 
to write new data to the device, but there was actually nothing to write!
Jan  8 18:44:08 localhost pulseaudio[1490]: alsa-sink.c: Most likely 
this is a bug in the ALSA driver 'snd_hda_intel'. Please report this 
issue to the ALSA developers.
Jan  8 18:44:08 localhost pulseaudio[1490]: alsa-sink.c: We were woken 
up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 
or another value < min_avail.

This looks a lot like a couple BZs for F11 that were closed a few months 
ago :

https://bugzilla.redhat.com/show_bug.cgi?id=506075
https://bugzilla.redhat.com/show_bug.cgi?id=520230

Sounds like a tough one with a lot of tail-chasing.

Anyway, I thought I'd mention it.

Smolt (needs updating -- still shows f11) :
