Thanks for the advice. This seems to be working a little bit better, but
I still have no clue how to define the inputs and the outputs via
pavucontrol. Everything I do that results in audio actually getting to
FoxTelem turns out to be through the laptops internal microphone. I can
verify this by clapping and seeing the display in FoxTelem change. What
are the settings in pavucontrol that needed to be made? Currently I have
GQRX (audio output on)
Java (audio stream on)
ALSA plug-in [java]: ALSA Capture from [built-in blah blah blah] (whole
bunch of options here, including the sink/source)
Built In Audio Analog Stereo (port speakers)
Uplink Sink loop_sink on Built-in Audio Analog Stereo
Virtual Source loop_source on Built-in Audio Analog Stereo
Profile Analog Stereo Duplex (whole bunch of options here)
Thanks in advance....
