Yes, I am. I tried using the following 2 commands:
pacmd set-default-source alsa_input.pci-0000_00_1b.0.analog-stereo
These 2 commands do work to switch back and forth in Sound preferences
between input devices, but I think I need another pair of commands which
choose between Monitor (the sound of a playing video) and the
microphone. Ideally, it would be nice to have a hot key assignment. I
can do that, but do not know the internal commands.
