My laptop's internal mic broke, so I looked for a way to replace it with the mic of an old Android tablet, connected via USB (it's very convenient to have this microphone always at hand without having to assemble anything when you have an idea, etc). I found this project:
https://github.com/gdzx/audiosource
and got it working without problems with Pulseaudio: the tablet's microphone shows in Pavucontrol as a device called "Unix FIFO source /tmp/audiosource (Microphone)", I can choose it in audio-recorder, and it records flawlessly.
Now I'm trying to take the next step and see of making it work with Jack, so that I can use the microphone in a DAW.
I've tried connecting to Jack with Cadence, the Pulseaudio > Jack bridge is enabled, but Catia's patchbay does not show this mic as a connection.
Do you think of something I could try to make this mic visible to Jack? It surprised me how simple to configure was this Audiosource program, "it just worked", but I'm wondering if such simplicity maybe also means that it doesn't have the code necessary to "talk to" jackd, etc... Thank you for any suggestion...
