@righthalfplane - I think it is actually a little more complicated than that. If you look at the source code for the function `setFrequency(direction, channel, frequency, [args])` (https://github.com/pothosware/SoapySDR/blob/master/lib/Device.cpp#L360-L398), you'll see...

Out of curiosity I just looked at what CubiCSDR (which I use as my reference in these cases) does, and I see that they always use the SoapySDR function `setFrequency(...)`...

As I said in my previous comment, the problem you saw might be specific only to the RSPduo in Slave mode (but not Dual Tuner or Master mode), because in...

Glen, I think the best way to install SoapySDR + support for the SDRplay RSPs on Linux is to follow the instructions from the Wiki (https://github.com/pothosware/SoapySDRPlay3/wiki), that comprise of these...

Glen, SDRplay does have an API version 3.07 installer for Linux ARM 32-bit - you can find it here: https://www.sdrplay.com/software/SDRplay_RSP_API-ARM32-3.07.2.run Unfortunately at this time I don't think they provide the...

Glen, this morning I picked up the Raspberry Pi 4, and I ran the following steps: - download and install the latest version of Raspberry OS (11 - bullesye) -...

@Ifilehk - thanks for reporting the issue. In order to rule out (or not) that it is a problem caused by the Python interpreter or the Python bindings, I wrote...

Tarik, I am not sure I understand your comment. As you can see from the gdb stack trace the mutex I am referring to is inside the SDRplay proprietary library...

Tarik, it's because `sdrplay_api_Open()` (the SDRplay API function that opens and initializes their API) is invoked only once, the first time `findSDRPlay` is called (see here: https://github.com/pothosware/SoapySDRPlay3/blob/master/Registration.cpp#L45). If you want...

Tarik, good find! Your solution of using `SoapySDR.unloadModules()` and `SoapySDR.loadModules()` is much better and more elegant than mine! As per your question about the reason of the way I am...
