> It would help if you want to see a backport to describe the impact /
include a testcase since that's a pre-require to issue a stable update
(https://wiki.ubuntu.com/StableReleaseUpdates)

ubuntu switched the *server* part of pulseaudio to pipewire-pulse. the
bug affects libpulse, which is pulled into applications which then
connect to either pulseaudio or pipewire-pulse. so even if the
pulseaudio (as in: the server application) is not used, pulseaudio (as
in libpulse) is requires these bugfixes

Title:
  pulseaudio: request backporting of upstream patch

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  i've been investigating bugs of the gstreamer backend of qt
  (QTBUG-122424, QTBUG-122423). it seems that we run into a pulseaudio
  bug that has been fixed in pulseaudio-17.

  what would it take to backport the corresponding fix?
  https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/745
  (i've verified that a local build of pulseaudio with that patch fixes
  the issue).

  edit: a very similar class of bugs requires
  https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/764
  to be backported
