I don’t know if this goes in Multimedia, or Applications, but I’m a newbie, so here it is.
I’ve got a clean install of EOS, and it’s running PipeWire with PipeWire-Jack. My goal is to get JACK Meterbridge to work with it. In case you’re not familiar with it, Meterbridge allows you to display a variety of audio-level meters using input from Jack. The plugin page for Meterbridge says, “The jack library and headers must be installed.” I’m hoping that PipeWire-Jack will work, but I haven’t been able to find any documentation that supports that yet.
Meterbridge is in the Arch repos, so I installed it using pacman without any problems.
I can get it to display a pair of Vu meters with the following command in Console:
$ meterbridge -t vu alsa_pcm:playback_0 alsa_pcm:playback_1
Registering as bridge-16322
Initialising OpenGL system
Can't find port 'alsa_pcm:playback_0'
Can't find port 'alsa_pcm:playback_1'
As you can see, Meterbridge can’t find the ports as I’ve identified them.
I used the PipeWire cli tool (pw-cli) to list my ports:
