Installed qpwgraph from Flatpak now Pulse applications have no Audio Interface

Post by SmoothMountain »

Greetings.

I'm on Ubuntu 22.04. PipwWire is not the default. I installed PipeWire and WirePlumber, and disabled (but not uninstalled) ALSA ald Pulse. Everything worked. I wanted a GUI, but the only options for qpwgraph were to build from source, or install from FLatPak. I used FlatPak. That broke all PW-Pulse connections.

In Display Settings > Sound the only output device is "Dummy Output"...

  • no on-board audio
  • no USB audio
    :shock:

So I uninstalled PipeWire, WirePlumber, and qpwgraph, and re-enables ALSA and Pulse. Still not output devices.
I removed and re-installed Pulse. Still not output devices.
I tried editing /etc/pulse/default.pa as described in this link:
https://9to5answer.com/usb-audio-interf ... pulseaudio
Still no output devices.

I'm running Reaper through a Focusrite 18i20. It works, with a few hopefully minor issues. I want to use PipeWire/WirePlumber, but I need to figure out why the apps that use Pulse Audio don't see any audio outputs.

Please help!

You don't need to use a flatpak or compile it. Add Rui's PPA, install qpwgraph from there

Some Focal / 20.04 audio packages and resources https://midistudio.groups.io/g/linuxaudio
