A bridge with Zoom?

[ve3meo]

Has anyone installed Zoom on JamBox and bridged its audio i/o with the Jamulus client i/o? No audio adapter needed but might be nice for monitoring.

I looked at PiKiss for possible installation of Zoom but it installs an X86 emulator and that version of Zoom so I'm guessing that would be a lot of overhead and present routing problems.

As of Zoom 5.5, the Linux version supports stereo so I'm hoping to make a stereo bridge. My case needs no camera and the Zoom screen can be minimised so the video processing burden should be minimised. If there is a headless version of Zoom, even better.

My advice is: Run Zoom on another device, probably the same one you use for the web browser UI (I use an iPad).
We don't run any audio through zoom at all, it's just so we can see each other.
If you really want to send audio to a zoom participant, and listening via Jamulus is not an option, run a wire from jamulus out to the device running Zoom.

Zoom audio is severely delayed. Also There is no Zoom arm client available. Some people have reported getting Zoom chromium plugin to work on RPI. For that you would need to enable the vc4-fkms-v3d overlay driver:

sudo sed -i "s|^#dtoverlay=vc4-fkms-v3d|dtoverlay=vc4-fkms-v3d|" /boot/config.txt

I have this driver disabled by default because it introduces overhead that can affect jamming apps, also it appears to have some bugs that can cause instability.

If you get Zoom browser plugin working, you'd then need to get the audio mixed in (might be able to do it with Patchage). And Zoom would likely degrade Jamulus/SonoBus performance.

My use case involves meetings/rehearsals that include participants on Zoom only who need to be able to talk with those using Jamulus audio (also on Zoom for video). I've been using two Win 10 PCs bridged by audio cables to do that, joining the audio from Jamulus with my personal video which means my camera is highlighted for everyone on Zoom no matter who on Jamulus is the active speaker. I thought I might do the bridging on JamBox or even normal Raspbian with a no-camera Zoom client. I didn't realise that there is no Zoom client for the Pi, just the Chrome extension. Given your caveats, maybe I'll just pursue it on my 11-yr old secondary laptop although I've had no success yet trying to do so with ASIOLinkPro, Reaper, Jack or Synchronous Audio Router.

Ve3meo, Not sure this is the right place, but I thought I would respond quickly as Kevin has been so helpful to me. You can use a program like voice meeter banana to route the audio from Jamulus to zoom on a pc. You need to set up virtual sound devices in banana that can be selected as audio inputs and outputs in zoom. I use “TO ZOOM” (Jamulus selected as a source) as a mic input and “FROM ZOOM” (zoom selected as a source) as an output. As Kevin mentioned, anything extra you try to do on the Pi will wreck the sound quality and performance of Jamulus. PC set-up: You need to run two simultaneous instances of Jamulus, one with “TO ZOOM” selected as both the input and output under input channel mapping and the second instance with “FROM ZOOM” selected as both the input and output under input channel mapping. Change the personal mix profile ID or alias to “TO ZOOM” and “FROM ZOOM” on both instances of Jamulus so that you can tell them apart. Change Jamulus settings for both instances to 10.67 buffers, uncheck “auto jitter buffer” and move both sliders up to 20. I use mono in, stereo out and shift the audio quality to “high.” Click the “mute myself” checkbox for the “TO JAMULUS” instance only. Connect to your Jamulus server on both instances to get things running. Click the mute buttons on the personal mix tab for “TO ZOOM” and “FROM ZOOM” on both instances, 4 times total. As other performers begin to join your server, make sure to check the mute button on the personal mix tab for each of them on the “FROM ZOOM” instance only. This will keep them from hearing an echo. Adjust the performer sliders on “TO ZOOM” to get a balanced audio feed sent to folks on zoom. This set-up as described will allow anyone on Zoom to hear Jamulus performers and it will also allow Jamulus performers to hear folks on zoom (applause, questions, etc) Hope this helps,

Thanks @yoyomatt4cello. Yes, we won't continue discussing Windows solutions here.
