Hi everyone, sorry for my bad english…
I’m working on a diy project and i’m approaching to develop with Alsa. I’m working on an old jukebox and i would like to use Volumio on a Raspi as a music server. I’d need to duplicate audio stream from my usbaudio to alsa loopback so i can process it with an external executable; i’m confident with C/C++ but not so smart with JS.
I tried with an handcrafted asoundrc file on my home but i think it doesn’t work. I’ve seen there is the new feature for audio routing in Volumio 3. Is there a boilerplate to create this virtual routing channel?
Sorry, thanks for you patience
