Dear Maintainer,

After an update last week I have issues related to audio in Telegram-desktop.
  - It hangs for 30sec a launch.
  - It hangs for 30sec when trying to read or record an audio message. And it
does not execute the task. Same for Audio calls.
  - It hangs for 30 sec when trying to open the call advanced settings panel in
Telegram.

I tried to read the logs and install other versions of the package.
  - v3.52 from the Testing repo.
  - v3.60 from the unstable repo.
  - v3.50 and v3.52 from the official github releases.

The definition of the errors changed a little in the logs but the issues
stayed.

I update APT with a mix of Bullseye, Testing and Unstable every week.
Before this update last week I could read and record audio messages, have audio
calls. And no hanging.

Logs at launch (it hangs 30sec before the "cannot open" errors) :

I found that this issue is related to wireplumber and is being treated currently
here :

https://salsa.debian.org/utopia-team/wireplumber/-/commit/a70f692eb5bacda64b54a93f5445f8ff8efaaa69

They will probably release to unstable this week.

I tried to apply the patch for Wireplumber, but it was not the issue for me.

But it gave me a lead. In fact wireplumber is conflicting with pipewire-session-
manager. Wireplumber is replacing it but pipewire-session-manager was still
installed by APT and the systemd service was not replaced by wireplumber.

I removed pipewire-session-manager, wireplumber and pipewire-pulse. Then
reinstalled them, and there is no more issue with Telegram.
