Pi / Audio Input and Output router
« on: January 13, 2016, 03:39:16 PM »
So, does anyone have any experience in routing audio input to outputs using the PI.. or BB for that matter.

What my goal is to have Audio coming INTO the PI on the USB adapter, and then routing through the PI to get Volume control over it, and then sending that audio stream out the pi either back out the same USB port headset jack or a different port (native on the B+..etc).

There may be some delay in audio, but that is fine for now.

What you're searching for would be something in ALSA.   I think that you might be able to set the MIC input to 'record' (or 'capture') and it would get looped back to the line output by ALSA, but it's been a long time since I've played with that, so my memory is vague.  You might be able to do it through the command line using 'amixer'.
