I have also been testing Clemens' patch for rate feedback format. It
works perfectly with the sdr-widget as well, when I set the feedback
format to 16.16 in 4 bytes (which OSX can understand). So now I can
have one firmware version that works under Linux and OSX.
I'm now working on rate feedback with UAC2. Clemens thinks the format
under UAC2 should be 16.16, samples per uFrame. However, I will have to
test with OSX to see whether it is accepting samples per millisec
(Frame) or samples per uFrame (125 microsec). Whatever OSX uses I will
probably use, as Clemens' patch has automatic format so can take
whatever format OSX uses.
Thanks Clemens for the great patch :-) OSX should adopt the same
