When playing bluetooth audio pipewire stutters

[Arief Mulya Utama]

Using bluetooth headset, pipewire stutters alot.

Stutters condition:
- When system is busy
- When there are intereference from others, possibly things like: Mouse bluetooth, mouse usb 2.4GHz, or Wifi 2.4GHz

Using wireplumber here, all pipewire and wireplumber already on High priority process setting.

Using this command to set the quant seems to fixed it / make it work lot better, almost no stuttering:

pw-metadata -n settings 0 clock.force-quantum 2048

Found it somewhere on the web.

Maybe we can put it as default value.

Has not yet test if using higher value makes them lot better.

Thank you for your bug report, could you submit the issue directly upstream on https://gitlab.freedesktop.org/pipewire/pipewire/ ?

Status changed to 'Confirmed' because the bug affects multiple users.

Note also that audio over PipeWire is not supported in 22.04. It should be supported by 22.10.
