Comment # 2 on bug 1208783 from Scott Bahling

When I start up my X session, pulseaudio is usually running and jackdbus, but
neither connected to the hardware. I usually see the issue when I run
"jack_control start" to start jack (which then bridges to pulse audio). Or if I
stop the jack server or kill jackdbus (which sometimes hangs).

What I just noticed is that pipewire was also running in the background. I was
not even aware that I had it running on this system and strange because usually
pipewire and pulse do not play well together. I have disabled the pipewire
service now and will see if the issue seems to go away.

But if you need me to reproduce let me know.
