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

[Alex]

Hi Daniel et al,

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.

Would you know the format used by OSX?

Thanks.

Alex
