Hi,
I don’t really understand the problematics of your issue, but in my
config I just delete pulseaudio from %desktop-services and add pipewire
in my home-services.
pw-jack and pulseaudio apps work fine for me this way.
config.scm:
(modify-services %desktop-services
(delete pulseaudio-service-type)
(delete alsa-service-type))
home-configuration.scm:
(service home-pipewire-service-type)
Specifically, I don’t understand why you try to start jackd through
pw-jack, you just need to start your app directly like the example in
the manual:
pw-jack mpv -ao=jack sound-file.wav
In hope that helps,
Noé
