Pipewire or Wireplumber using 100% CPU after using Bluetooth microphone

[murilosr]

I saw the issue #3, but I think this is a different issue. Something changed in the last days (I started noticing on July 21st).

After I use the bluetooth microphone on Microsoft Teams (I tested with others softwares, like Google Meet on Google Chrome, but I coudn't reproduce) it changes the Headset Profile to Handsfree HSP/HFB codec mSBC (as it always had changed, and it wasn't bugging). When the call ended, the headset loses the connection and wireplumber starts to use 100% of CPU (I noticed because my notebook turned on all its coolers).

When I reset the services, the CPU normalize.
Command used to restart:
systemctl --user restart wireplumber pipewire pipewire-pulse

May be worth reporting the issue to https://gitlab.freedesktop.org/pipewire/wireplumber
We're keeping in sync with upstream releases and debian packaging.

I've linked a pull request that might fix it. It would be useful if you could test it to see if it works. When the package has been built, you can add the testing repository with

git clone https://github.com/pop-os/pop
./pop/scripts/apt add wireplumber

Remove the testing repository after the PR is merged or closed with

./pop/scripts/apt remove wireplumber

And log out after updating/downgrading the wireplumber packages.
