Qubes OS version:

R4.0-rc2

Steps to reproduce the behavior:

  1. Start some applications in VMs
  2. Log off
  3. Log in

Expected behavior:

All applications reappear and audio works in VMs since GUI daemons are restarted.

Actual behavior:

GUI daemons don't restart automatically.

If restarted manually, by deleting /run/qubes/guid-* and running qvm-start-gui --all, then audio doesn't work since pacat-simple-vchan seems to hang before connecting to PulseAudio.

If restarted manually, by deleting /run/qubes/guid-* and running qvm-start-gui --all, then audio doesn't work since pacat-simple-vchan seems to hang before connecting to PulseAudio.

This issue is present also on 3.2. Can be workarounded by reloading module-vchan-sink in the VM:

pacat unload-module module-vchan-sink
pacat load-module module-vchan-sink

GUI daemons don't restart automatically.

This is a duplicate of #3147

Indeed, reloading module-vchan-sink now seems to work for me.

It's a bit strange because I tried doing exactly that before filing the bug and it didn't seem to work, but maybe I had the system in a somewhat strange state as I was trying a bunch of things (perhaps pacat-simple-vchan not running or no audio devices)

Is there a workaround/fix for Qubes R4?

pulseaudio: support reconnecting
22e6859 
Recreate vchan servers (libvchan_server_init()) on disconnection.

This fixes audio in the case of Xorg crash (see
QubesOS/qubes-issues#5273), and any kind of GUI restart.
