I use SDRPlay with gnuradio-3.8 with linux and it works fine. The gr-soapy backend works better than the gr-osmosdr one however. In my case I use sdrplay-2.13.1, soapy-sdr (git master branch as at 2020-07-13), soapy-sdrplay (git master branch as at 2020-06-29), gnuradio-3.8.2.0 and gr-soapy (git master branch as at 2020-06-07). In addition, to use SDRPlay with gqrx, I use gr-iqbal (git master branch as at 2019-12-01) and gr-osmosdr (git master branch as at 2020-08-05). However, you should use the gr-osmosdr block's soapy backend with soapy's sdrplay driver (pass the arguments "soapy=0,driver=sdrplay" to the gr-osmosdr block), and not the sdrplay backend which no longer works properly.
