Hey there, Greg.
Easily the most handy thing I've put on my Ubuntu linux system is the Pulse
Audio Volume Control utility. It provides a GUI to easily control what
audio device each app plays OUT to, as well as what audio device some other
app records FROM. So, it's very straightforward to route the audio to suit
any need you might have when you want to do something like send your SDR
audio to an SSTV decoder or in this case, the FoxTelem app.
(Tip: you'll normally want to record from the "monitor" of your audio
device... you'll see it on the drop-down)
(Tip #2: you won't see an app in the utility until it's actually playing
To install: sudo apt-get install pavucontrol
... and to run it: pavucontrol
Of course, I use it so much that once it's running, I right-click the icon
to "Lock to Launcher" so that I can run it the next time with just a click.
Hope that helps!
