Is the RSP1A supported ?

The reason I ask, the gain etc seems to work (I get noise etc), but no RF seem to come in.
I tried to change the flavour setting, but no luck so far.

However, if run gqrx using the sdrplay driver, then shutdown gqrx and the sdrplay driver, and relaunch using Soapy/SoapyMiri, it works fine, until I disconnect the RSP1A physically.

Which makes me wonder, whether there is a switch or similar which needs initialization?

I'm not that familiar with RSP1A. Presumably there's a multiplexer for switching the different outputs while providing some physical filtering. I do know the GPIO pins are utilized to switch in-out the DAB and AM broadcast notches: ericek111/libmirisdr-5#3 (comment)

It has one antenna only, but yes I believe you are most likely correct...
