Device 88:C9:E8:CF:1C:36 WH-1000XM5
Device F0:AE:66:9A:EE:25 soundcore P20i
Description of Problem:
Bluetooth audio started to stutter frequently a few weeks ago (was perfect before). Tested 2 headsets (Soundcore P20, Sony WH-1000XM5) with BT various codecs (SBC, AAC, LDAC).
Does not happen in "hands free" mode or when playing to the internal speakers.
During playing CPUs seems in low levels and the system is not under any load
RTkit installed and seems to work (set pipewire and wireplumber processed to -11)
Tried to change various params (clock rate, allowed rates...) with no improvment.
How Reproducible:
Happens almost all the time. Simply start playing audio file locally or from the internet (Youtube, Soundcloud, etc...)
Actual Results:
Frequent stutter of the audio
Expected Results:
Should play smooth without interruptions.
