No sound (`module-vchan-sink` crashing) in Xenial TemplateVMs

[SaswatPadhi]

Qubes OS version:

Qubes release 4.0 (R4.0)

Affected component(s):

Xenial TemplateVMs

Steps to reproduce the behavior:

Build a new Debian-based TemplateVM with Ubuntu Xenial

Expected behavior:

Sound works out of the box

Actual behavior:

pulseaudio fails to start because module-vchan-sink cannot be loaded:

What pulseaudio version you have there?

It's 8.0 (the default with Xenial).

I am experiencing the same issue (pulseaudio-qubes module not starting on Debian VMs) since pulseaudio went from 10.0-1+deb9u1 to 11.1-5. It was working fine during 9.0 to 10.0 (with the required re-link of the module into the proper directory).

Confirmed that sound works again after downgrading back to 10.0.-1

Artful (pulseaudio 10.0) and bionic (pulseaudio 11.1) have sound working out the box.
