sonobus VS elkpi-sdk

Sounds like you could use https://sonobus.net/ and possibly https://vdo.ninja/ but you might have that already covered with jitsi.

Our collaboration software might look something like Sonobus and vdo.ninja for live jamming (if we're close enough), Discord or Whatsapp for chatting, maybe Area for reviewing mix-downs, and Bandlab for stem-sharing (Reaper too, if you've got it). I'm open to all suggestions. I'm also interested in learning how to use something like Sonic Sound Picture to do visualisations, or maybe creating AI generated animations, if deciding to upload anything to YT.

If you're in a 2000km of each other and have good wired connections, Sonobus is absolutely amazing, especially in conjunction with video.ninja.

There's a plugin out there for this. https://sonobus.net

Most of these Android TV boxes can pair with bluetooth speakers, head phones and ear buds, however most mobile phones can't receive audio through bluetooth, they can only transmit it. I think the aux is disabled when bluetooth is used, or maybe it was the opposite. I'm not sure now because I tried to do this a few years ago and gave up because it was easier to just buy a bluetooth headset. Most of the apps I found were not free and were more about pc to mobile. There may be some more apps around now. Most popular apps I considered, were not bluetooth but WiFi network ones like this https://sonobus.net/

This sounds promising: https://sonobus.net/ Multi-user, multi-platform, open-source, completely free.

If you're looking to do this over wi-fi, try Sonobus.

Looks like it uses a "Yocto" script - https://github.com/elk-audio/elkpi-sdk - https://www.yoctoproject.org/

I thought of Ubuntu Studio as well, but it looks like Elk is intended to be more lower-level / for appliances. I'm not totally sure though, but I'm guessing it doesn't come with the full suite of Ardour etc.

I do wish there was something like Ubuntu Studio, except focused on audio-only (and more polished / supported). Mostly just because JACK + low-latency kernels are an ordeal to set-up and maintain on a normal desktop, so it's much easier to just install a pre-configured distro on a studio computer and be ready to jam whenever inspiration strikes. Unfortunately KXStudio as a separate distro isn't around any more. I still use a KXStudio 14.04 install on an old (airgapped) DAW computer.
