This weeks update installed a new program pipewire on machines with bluetooth - I do not see it on machines without bluetooth.
On most machines it is in sleep state.
On Dell E7440 it is in running with a -11 nice. kill -9 just causes it to reload.
Since I cannot see any reason for it to be be loaded - I did a zypper rm pipewire* and removed it.
I suspect it connects pulseaudio to bluetooth and since I don’t use bluetooth I removed it.
