Unfortunately your perf doesn't have support for debuginfod, so we don't
have any symbols to go off in that perf report.

You can try installing the debug symbol packages manually. Details are
in https://wiki.ubuntu.com/DebuggingProgramCrash but for me the
following worked,

$ echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee -a /etc/apt/sources.list.d/ddebs.list
$ sudo apt update

Now find the version of pipewire installed,

$ apt-cache policy pipewire
pipewire:
  Installed: 1.4.5-1ubuntu2
  Candidate: 1.4.5-1ubuntu2
  Version table:
 *** 1.4.5-1ubuntu2 1001
       1001 http://mirror.mythic-beasts.com/ubuntu questing/main amd64 Packages
        100 /var/lib/dpkg/status

Then for me, the dbgsym packages to install are,

$ sudo apt-get install pipewire-bin-dbgsym=1.4.5-1ubuntu2
$ sudo apt-get install libspa-0.2-modules-dbgsym=1.4.5-1ubuntu2

Now you can try the perf record again, or if that's still not being
symbolic for whatever reason, try attaching to the pipewire process with
`gdb -p <pidof /usr/bin/pipewire>` and run `bt` at the gdb prompt. It
should statistically show the stack that is spinning.

Title:
  Pipewire uses 100% of a CPU core. Can not connect to pulseaudio.

Status in pipewire package in Ubuntu:
  Incomplete

Bug description:
  pactl commands freeze and don't display anything. pavucontrol tells
  "Establishing connection to PulseAudio. Please wait...". Audio does
  not work in system. This issue is reproduceable sometimes. I don't
  have information on how to give first-aid in this case. I'll just kill
  the process and try to restart pulseaudio.
