You will need to modify the device ID. pw-cli list-objects will show everything

You *may* need to modify the index value to turn the setting to off

Thanks for the input, @christoph!

It doesn't have to be persistent… In fact, it would be nicer to just enter a command and exclude the device just for the session… Any hints?

hi Mitsch,
recently, i have disabled the onboard soundcard of my laptop using pipewire on arch linux with this:
https://wiki.archlinux.org/title/WirePlumber#Disable_a_device/node

i want the system to just use usb soundcards. and the system always automatically connected the onboard card to the first ins/outs which i didn't want.

it worked like a charm.
viele grüße!

Hi!

I'm using Linux-Show-Player (LiSP). LiSP allows you to make use of any audio port there is with the jack-output-plugin but, unfortunately, under pipewire it just doesn't. (There seems to be a bug in gstreamer-jack.) So, I have to switch to jack, from time to time.

There is a cool configuration-script in Ubuntu-Studio on my main multimedia-workstation, which allows switching from pipewire to another config where I can start jackd - and going back without any hassle. But on my laptop I'm running Debian.

It's said that pipewire works great with jackd. Unfortunately, it's not self-explaining…
Under Gnome - what steps do I need to take without de- and reinstalling anything… Keeping pipewire alive, but excluding a sound device, f.e. the one that I normally plug on the USB bus and then starting jackd on it.

Should not be too hard, is it?

Greets!
