I also had this issue. This was greatly improved since May and I am now
using it instead of PulseAudio. Check that you have rtkit-daemon
installed. It helps.

wireplumber (up-to-date sid) on an armhf laptop:
- same problem as above (even with rtkit + force-quantum) which wasn't the case with pulseaudio
- micro no longer recognized
- hdmi audio jack no longer recognized
- headphones have no sound
This laptop have a rockchip alsa ucm2 profile, alsa sees speakers, micro, headphones, hdmi,
but not pipewire apparently.
