Pipewire audio server unusable

Description

GNOME 40 introduces a new sound server, Pipewire, to replace pulseaudio to control sound under Linux.

Fedora 34 makes Pipewire as default, while it has a pulseaudio module to maintain compatibility, VirtualBox can't play sound with Pipewire, and it affects video playback as well.

Under GNOME settings, there is a testing option under sound preferences, no sound is available in the test.

If there is a video in a web page, like YouTube, sometimes sound can play 2-3 seconds but then the video will be muted, and frames are freezed as well, not only sound is unavailable but the video is affcted as well.

I tried to remove Pipewire and install Pulseaudio, everything is ok and back to normal again.

As Pipewire introduces many new features and better integration in future Linux development, it would be important to fix this issue before pulseaudio is completely phased out (it may take 2-3 years though...).

I had similar issue with "Intel HD Audio" emulated inside the VM. Looks like switching to "ICH AC97" does the trick for me.

Until virtualbox support pipewire directly, one workaround would be to see if it can use the pulseaudio/alsa bridges.

If a user is

  • logged into GDM/GUI as unprivileged user
  • started a terminal window, in which, a sudo root shell is started
  • and from the root shell a root process VirtualBox Manager is started

Then one might need to set XDG_RUNTIME_DIR environment variable for the root Virtualbox manager process and its child processes to access pipewire-pulse sound bridge server.

I heard/got sound from inside VM only once among serveral reboots, with intel-HDA, so not sure if that is sufficient.

That said F35 still in beta, not exactly sure if there are chinks to be fixed.
