PulseAudio Connection Terminated

[entr0py]

On a freshly rebooted Qubes 3.1, dom0 pulseaudio process consumes 100% cpu every 5 secs. Pulseaudio Manager shows a connection to server for a split second before announcing `Failure: Connection terminated`. This cycles continuously.

Not sure what triggered this issue. May have been recent updates and/or "Attaching audio-input to VM". Have not experienced this in the prior year of using Qubes. "Detaching audio-input" does not work.

Tips to troubleshoot? TIA.

1. Deleting config files `~/.pulse`, `~/.config/pulse` did not resolve.

2. PulseAudio Manager Client Information says:
Linked to Library 5.0.0
Compiled with Library 4.0.0
Is that a problem?

3. pulseaudio -vvvv:

No kernel error messages.
Machine has 16GB RAM - dom0 has 4GB.
No changes in hardware since last successful boot.

Really need some help with this.
Machine is locking up every 5 secs. Plus I need audio.
Thanks!

(For a few minutes I thought the issue might have resolved itself, but when I launched PulseAudio Volume Control, it went haywire again. No idea if those events are related.)

Maybe it is related to HDMI audio output? Try to disable it (for example
unload snd-hda-codec-hdmi kernel module).
