Hi,
I can not get working jack audio server on my G5 under Bookworm PPC64 with kernel 5.15.0-2.
Qjakctl starts itself with this message:
>>>>>
17:11:51.606 Statistics reset.
17:11:51.651 ALSA connection change.
Cannot connect to server socket err = No such file or directory

qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), sequence: 201, resource id: 18, major code: 131 (Unknown), minor code: 46

and when trying start jack server from there it wont start:

Starting from the shell gives the same results.
Changing hardware/outputs (I have a few) turning realtime mode off also does not help.
