Hey folks, having some trouble with this module. Running a find or a probe from SoapySDRUtil while the SDRPlay module is =present= in /usr/local/lib/SoapySDR/modules0.x, even if find-ing or probe-ing against another driver, causes SoapySDRUtil to hang. Simply doing a "sudo rm libsdrPlaySupport.so; sudo ldconfig" restores functionality.
Ubuntu 21.04:
Linux lenny-bu 5.11.0-18-generic #19-Ubuntu SMP Fri May 7 14:22:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
SoapySDR 0.7.2 (either from binary package, or compiled from source package)
-- OR 0.8 (compiled from latest source).
SoapySDRPlay3 (compiled from latest source, recompiled to switch between Soapy 0.7.2 and 0.8).
Attachment:
CMakeOutput.log
The msi* kernel drivers are blacklisted.
This same constellation (using Soapy 0.8 compiled from source) worked fine on this same PC under Ubuntu 20.10/64.
Example 1 - Attempting to use SDRPlay driver, with both
RTL-SDR and SDRPlay RSP1 hardware installed (any
combination with/without hardware yields the same behavior,
though the kernel and Rafael 820 message only appear if
the RTL-SDR in plugged in)
