Re: [alsa-devel] OSX Core Audio ASYNC OUT with rate feedback format ?

I have successfully interfaced the sdr-widget with Linux alsa-driver for ASYNC OUT with rate feedback. Found out after much trial and error and reading of the usbaudio alsa-driver source code that you are using 12.13 as the format for the feedback rate !!! I was trying with 10.14 (UAC1 v1.2 specs, I think) in 3 bytes, and 16.16 (USB 2.0) in 4 bytes for quite a number of days with no success !!!

However, 12.13 in 4 bytes, whilst working like a charm with Linux, does NOT work with OSX.

Linux currently doesn't look at the endpoint packet size to determine the feedback format.

I'll change the driver so that it accepts any format.
