Audio Through USB

Using JACK2 net

NOTE: This requires v1.4 or later.

First, connect the MOD Duo to your PC via usb cable.
Make sure to open port 19000 on your firewall. If you use Linux with ufw, you can use:

sudo ufw allow 19000

Then, ssh into the Duo, and run:

touch /data/enable-netmanager
systemctl start jack-netmanager

NOTE: You only need to run this command once.
The next the Duo boots, jack-netmanager will be loaded by default.
Delete the '/data/enable-netmanager' file inside the Duo to remove this auto-start feature.

Now run jackd on your own computer (connected to the Duo via USB), like this:

jackd -R -P 80 -d net -a 192.168.51.1 --opus -C 2 -P 2 -i 1 -o 1 -l 4 -n slave -s

Adjust the parameters as needed, but keep the client name as 'slave'.
