SDR++ sourcecode build failing , ‘struct RtAudio::DeviceInfo’ has no member named ‘probed’

[ih8censorship]

SDRPlusPlus-nightly/source_modules/audio_source/src/main.cpp:93:26: error: ‘struct RtAudio::DeviceInfo’ has no member named ‘probed’ 93 | if (info.probed && info.inputChannels < 2) { continue; } | ^~~~~~ make[2]: *** [source_modules/audio_source/CMakeFiles/audio_source.dir/build.make:79: source_modules/audio_source/CMakeFiles/audio_source.dir/src/main.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:1939: source_modules/audio_source/CMakeFiles/audio_source.dir/all] Error 2 make: *** [Makefile:136: all] Error 2

that's the error I get at about 60% through the build process. Any ideas why? I'm running opensuse tumbleweed, and I have version 6.0.1-1.5 of librtaudio and its development files

edit
In a very roundabout way, I found this, so going to focus on that #1243 looks like the fix is to downgrade to version 5.2 of librtaudio. which would be great if I could actually find the package for version 5.2 or if the author of rtaudio had older versions on his website
