A SDRPlay device has never worked for me either. There's some issue with how samples are processed compared to a RTLSDR-device. 8 vs. 14 bit per. sample perhaps?

I see the same myself. It's some issue with the CPR (*Compact Position Reporting*) algorithm used for message-type 17 and sub-types **[9..18+20,21,22]**. Probably some math-rounding error in [`decode_CPR()`](https://github.com/gvanem/Dump1090/blob/main/src/misc.c#L2131) or a...

The new `gui/soapysdrinpuyt.cpp` does not compile due to the use of VLA. Errors: ```c gui/soapysdrinput.cpp(494): error C2956: usual deallocation function 'void operator delete[](void *,std::align_val_t) noexcept' would be chosen as placement...
