All the channels should now be available. Go to the Configuration tab, click on the Profile drop-down menu under your card, select Pro Audio and you should be good to go. I haven’t figured out how to do this on the command line yet, but it’s very easy to do this in PulseAudio Volume Control (PAVU). The remedy is to activate the pro profile. If you invested big money in 18 channels I/O this seems a bit sad. The default configuration is of the consumer kind, which means stereo in and stereo out. More details on configuration can be found here Access All Your I/Os So, in short: set the samplerate globally, mess around with buffer sizes per application. Pipewire will resample audio as required to get PulseAudio, jack and ALSA working together. … you will end up with a buffer size of 128 and a samplerate of 48k. PIPEWIRE_LATENCY =256/96000 your_application Currently the samplerate of pipewire is fixed globally, and can be set in /etc/pipewire/nf. There is very little need for any specific configuration, which was almost shocking for a long-time Linux musician. I might have gotten a bit more xruns than I would normally gotten, but not show-stoppingly so. No fiddling around with custom-made scripts to switch between internal and external interfaces. Also: For the first time since I abandoned macOS for Linux my computer automatically swapped sound card when I plugged in my Fireface UCX. pipewire emulates jack whenever a jack client is launched. If you, like me, run jack on login, then make sure to disable whatever script you’re currently running. Replace paru with your preferred AUR helper. However, if you prefer, you could simply remove your existing jack/jack2 packages instead of installing the dropin. Paru -S pipewire pipewire- Īll the packages except pipewire-jack-dropin are in the extra repo. Here’s a preliminary tour of what I found out: Installation Last week I decided it was time to check out this fabulous new invention, and so I set about making it work for me. Now you should be able to just run your application, and sound will magically appear from your speakers. No more worrying about whether your application supports jack, PulseAudio or both. The pipewire promise is one of easy, plug-and-play configuration of all your audio devices. Now, however, Wim Taymans at Red Hat is working on something that might just bring us from the dark ages into an era of enlightenment, at least as far as the end user is concerned: pipewire. Getting ALSA to work together with Jack to work together with PulseAudio is an esoteric business worthy of the deepest forms of black magic. At least, this used to be the predicament. Or, alternatively: Good luck getting professional audio properly configured on Linux. Setting External Audio Interface as Default.
