Hi Al,
fine that you made it finally.
I tried to setup snd-aloop as you told me and found, that this module is
allready compiled in Ubuntu 18.04.
I had to include following lines at the end of
/etc/modprobe.d/alsa-base.config:
options snd-xxxxxx index=0
options snd-yyyyyy index=1
options snd-aloop index=2
then start with: sudo modprobe snd-aloop
The problem is:
when I reboot the system I can seen my USB headset and the internal
sound card as available connections in the audio part of FreeDV.
After I start snd-aloop I can see the additional loopback there, but
either the USB-headset or the internal soundcard is gone.
I believe that has to do with some setting in general audio input/putput
section or in the volume control section.
I could produce a nice internal loop and could hear the great audio of
mode 2020.
I could connect the FreeDV input to the WebSDR, but I could not hear the
decoded signal, as the USB-headset was gone.
Just read about JACK Audio Connection Kit. Will try to install and run
later today.
Any further proposals?
Regards
Gerhard OE3GBB
