panoramic spectrum viewer: device specific tweaks

[g4ixt]

I built SigDigger, using the script, on a Raspberry Pi4 8Gb. It took a few attempts but the terminal messages helped me to resolve the missing dependencies. However it wouldn't run with my LimeSDR-USB and was reporting "error connecting to pulseaudio server". I read the user guide more carefully and everything I could find via Google and tried re-building with the various 'exclude' audio options but it made no difference.

Then I added "driver" "lime" in the device-specific tweaks for SoapySDR arguments and that fixed it and it works. "Device" and "serial" were already populated after I selected the LimeSDR-USB. I can't run more than about 2Ms/s but I haven't investigated optimising yet, perhaps I need to run volk profile or something.

Now I have tried the Panoramic Spectrum View and it gives the same "error connecting to pulseaudio server" but doesn't have the device-specific tweaks option. Is there any way to enter them?
