Reproducible: Sometimes

Steps to Reproduce:
1.Boot
2.Suspend
3.Resume
4.Suspend again
Actual Results:  
alsactl wireplumber Freezing user space processes failed

Expected Results:  
Suspend just worksTM

Might have to do with suspending/resuming multiple times sometimes docked sometimes undocked. Regular Lenovo docking station with sideways sliding double USB-C/Ethernet connector. BTW: Lenovo ThinkPad T14 Gen 1 AMD, model 20UES1Y600.
