Hi Dominique,

thank you for your reply and the link :)


I configured jack with patchage. Since it is jackdbus (not jackd) it
is - as to my knowledge - not compatible with qjackctl any more...

I will see, how to disable the not wanted audio chips to only use the
one on the motherboard.

Later I will post again, whether I had success or not...fingers
crossed ;)

Best regards,
mcc
