Hi Alan
I have an RTL dongle, SDRPlay and Adalm Pluto.
I installed PothosSDR-2021.07.25-vc16-x64.exe, plugged in the RTL and Pluto and tried CubicSDR first.
Cubic SDR sees the Pluto, SDRPlay and RTL dongle. SDR Console also see them all.
I then tried SparkSDR. Spark does not recognise the Pluto. The message in the console window is:
starting
using gpu False
MidiInWinMM::initialize: no MIDI input devices currently available.

Selecting the RTL dongle, listening to Radio 4 FM (no activity on amateur VHF) through my white stick 2/70 antenna the sound is fine in mono, noisy when stereo is selected. The waterfall is odd, with periods of just spikes that are not heard. - see attached image. These seem to coincide with silence.
Stereo sounds fine with SDR Console. Sample rate makes no difference in Spark.
I know it will be on your todo list but some calibration for the frequency will be needed - my dongle is some way off.
