Hi Mark,
Can you try disconnecting HDMI and see if it works?
The hdmi audio driver took place of the loopback devices. If it works, better blacklist the hdmi audio driver as a stop gap solution.

I fired up my sBitx DE with the latest v2 software and the waterfall is all on.
In the past, I've seen this and it's been an issue communicating with the WM8731
If I start up sBitx via ssh, I see all kinds of audio (ALSA and Jack) error messages starting with
Error opening loopback playback device plughw:1,0: Unknown error 524
See the attached file (error.txt) for all the gory details.
I think the loopback is configured properly. This setup was working a couple of days ago.
The attached file aplay.txt shows the output from aplay -l
In the past, when I have seen this behavior, rebooting or restarting sBitx will make things work, but I've restarted sBitx and rebooted several times - no change.
I've double-checked /boot/config.txt and /etc/rc.local (also attached) and both seem to be configured properly as per install.txt
FWIW, I am planning on demo'ing the radio at my local ham club meeting tomorrow night. I hope I can get things resolved before then.
