i am building a mobile sound box with raspberry and amp+.
Streaming audio by wifi works fine.
I would like to have a line in jack to connect an mp3 player or a cellphone.
I use a cheap usb soundcard. Both are recognised correctly.
Now i need a way to link the line in of the usb soundcard to the amp+. Maybe this is possible with jackd? Are there any how-to's?
