At dom0 pulseaudio proccess always eat 100% of CPU. If I kill it,

to disable pulseaudio start after kill.

Same problem here, only by updating though.

Had similar symptoms on Qubes 3.1. If you have multiple audio
adapters (ie Onboard + HDMI), disable one. (On KDE, it was
PulseAudio Volume Control > Configuration. Don't know XFCE.)

I also have multiple (incl. external). Disconnecting the external one
does not appear to help though.

Pulseaudio child processes constantly die and get started again, i.e.
the PID is changing every 1-2s. I guess that's not normal? Sound in
VMs is stuttering.

rsyslogd also eats quite a lot of CPU, but I bet it's due to the
pulse logs.

Sample log and /etc/pulse/default.pa attached.

Anyone got an idea?

In my case, the Onboard and HDMI adapters kept trying to connect, kicking out 
the other adapter. The machine would basically lock up every few seconds and 
CPU would max out. Same symptoms as you describe with the PIDs.

What I did specifically was go to Configuration tab and set Profile to 'Off'. 
One of the dom0 updates caused this setting to revert to its default. Perhaps 
you've got another adapter besides the USB, or the machine keeps looking for 
the disconnected adapter?

You were 100% right.

In my case I had connected a new GPU which had registered itself as new audio output device (HDMI) and apparently kept pulseaudio busy.

For reference:
Non-KDE users can pop up a dom0 console and use the "systemsettings" command to get into the GUI. There you can go to Multimedia -> Audio Hardware setup and switch the unneeded sound cards off (Profile = off).
