[App_rpt-users] Monitor Audio

[Doug Crompton]

Another thing I thought of is that you could add a second node and sound FOB. It could be an unmodified FOB as you would only be using it to monitor. Feed the output to an amplifier and connect the node to what you want to monitor. See the setup how-to at hamvoip.org for info on adding a second node.

Congratulations on getting your RPi2 up.

The RPi2 has HDMI audio output. Allstar has a second audio channel which could be used for monitoring purposes. This is the B channel in  simpleusb-tune-menu.  You could route that to an amplifier. 

There are many other ways to monitor. You could use iaxrpt on a PC connected to your node. You could add a second node and monitor another connection. There is much flexibility. 
You also don't need a radio just a USB FOB and an amplifier and Mic. See the radioless how-to at the hamvoip.org site.

Also try to ask RPi2 and BBB question on the arm-allstar forum. You will get better response there from a large group of users.

I have everything up and running on a Raspberry PI 2 with a DMK URI to the radio etc. My question is has anyone used the onboard sound card to do an aux output for monitoring purposes? This could come in handy in my situation and I was wondering if anyone has done it and if so, how did they do it?
Thanks,
