[Pkg-utopia-maintainers] Bug#1055825: pipewire v0.3.84 breaks HDMI audio

Until pipewire v0.3.83, I had some mixture of pipewire and pulseaudio
installed;
it was then possible to switch the output of a playing audio stream between the
external speakers and the TV, with the "pavucontrol" utility.

pipewire v0.3.84 broke that. It forced the removal of pulseaudio (except some
libraries),
and disabled HDMI audio completely. HDMI output can still be selected in
"pavucontrol",
and the amplitude indicator wiggles appropriately, but absolutely nothing comes
out of the
TV speakers. Switching the stream back to the analog speakers works properly;
switching
to HDMI produces silence.

I have now downgraded pipewire to v0.3.65/stable, and everything works properly
again.
A playing stream can be switched back and forth repeatedly between speakers and
TV,
with no problems. pipewire v0.3.83 is no longer available in the archive for
testing,
but something between v0.3.65 and v0.3.84 broke HDMI audio completely, at least
with this
hardware configuration, which doesn't seem particularly unusual.

Here are the relevant package versions (for working configuration);
everything else, including Linux kernel, is current Debian-testing.
