pipewire and Komplete Audio 6

Hi *, among others I have a Native Instruments Komplete Audio 6 device plugged in one of my machines. Since Tumbleweed moved from pulseaudio to pipewire/pipewire-pulse, I sometimes have problems to switch to that device for output; it simply doesn't play anything. Switching back and forth in most cases cures the problem. Besides that I can't select some of the input and output connectors of the device. So does anyone know how to configure that device correctly? For pulseaudio I had to provide a special /usr/share/pulseaudio/alsa-mixer/ profile-sets/native-instruments-komplete-audio6.conf, which I found somewhere on the internet back in 2015, but I couldn't find anything on how to do it for pipewire. TIA. Bye. Michael.
