[Jackaudio] Trying to use Jack to play wav from Windows to Linux

by James Lehman

Hello everyone. I have been trying to get this for many weeks. I want to use a Pi (any Pi) with a sound device on a private wired network as an output device (with a sound device attached). It has been very confusing trying to figure out what to use, considering that now PipeWire seems to have taken over everything and it seems to emulate the behavior of Jack2 and PulseAudio. I can get it working as long as everything is Linux, but that seems to be only when PipeWire emulates PulseAudio. When I try to put Windows into the mix, I find that there is really no support for PulseAudio in Windows. So I fall back to trying to use Jack2. It looks like it should be so simple, but I'm not getting anywhere. I am able to setup what looks like a connection by running jackd on the Pi as: #Server jackd -d alsa -d hw:3 -r48000 -S & jack_load netmanager -i"-a 10.1.1.10 -p 19000" And jackd on the Windows machine as: #Client jackd -R -P 70 -d net -a 10.1.1.10 -p 19000 When I open the Graph in qjackctl on the Pi, I can see the Windows client device objects when the jackd server is running on the Windows machine. I have no idea how to play a wav file from Windows into this connection. Any help would be greatly appreciated! Thanks! James.

[Jackaudio] Help with blocked USB keyboard devices on RPi 4B

by Hanns Holger Rutz

Hi there, I'm a bit frustrated, because I am setting up a sound installation out of reach, and need a remote shutdown key. I had a Logitech R400 presenter lying around, so I tried that. It works fine on my laptop (Debian 12), using KeyState UGen in SuperCollider. But on th RPi 4B (Raspbian 11, for reasons) as soon as jackd is started, the keyboard input is blocked and doesn't register. I first thought, it might be that the Logitech uses bluetooth or something similar, so I got a Flirc USB dongle. The same behaviour: works fine on the desktop, but on the Pi, as soon as jackd starts, input is no longer received. If I kill jackd, keyboard input comes back immediately. I tried to use different USB ports, makes no difference. The audio device in a trusty Logilink UA0099 class compliant USB interface. (To reiterate, using this same setup on my laptop has no issues). Any help is appreciated. Best, .h.h.

[Jackaudio] Re: JACK suddenly doesn't work with Reaper anymore

by Christian Alpen

Btw. I got this fixed. Had to "Run JACK as Admin", now all applications can connect again.
