no audio from Zoom participants #366

I'm using version 5.13.4.711 of the Flatpak on Fedora 37 KDE Spin. Zoom meeting links open in Firefox then launch the Zoom flatpak.

I see the other participants in the meeting, chat works, but I don't hear any audio. The Zoom [Join Audio] button appears but clicking it does nothing. There are no error messages in journalctl.

The Zoom "Test speakers and microphone" dialog that appears before you join works fine, which suggests the flatpak can access sound. The KDE Skrooge flatpak makes sounds fine.

Other bugs, mostly closed, indicate that Zoom depends on pulseaudio. Fedora 37 uses Pipewire which provides the pulseaudio API. I started a --devel instance of zoom to try to debug this; I ran a plausible /app/extra/zoom/ZoomLauncher command I saw in ps output; this started Zoom and I was able to join the meeting, but still no sound from meeting participants. There were no console errors. In this --devel instance I typed paplay /app/extra/zoom/sip/Hangup.WAV and it made the sound. I also ran pactl info

  [📦 us.zoom.Zoom ~]$ pactl info

so audio seems set up in the flatpak, but whatever Zoom is doing to play meeting audio, it's not working.

What else can I do to debug this?

Of course, you should double check all of your audio related settings in zoom's settings menu. I don't personally use the desktop client, so maybe there is some sort of participent-specific volume adjustment (similar to discord) that got messed up?

Additionally, you could try uninstalling zoom with flatpak remove --delete-data us.zoom.Zoom, then reinstalling, to see if starting with a blank configuration helps.

The troubleshooting you have already done makes sense (very nicely explained), and to me confirms that the issue is internal to zoom.
