Sorry about that dummy mistake i forgot the EDMA :) actually was the
first patch that I had re-base after initial support but for some
reason I decided not to apply now in Audio support. Thanks a lot
Caglar it works perfect, will make a test case for ALSA utils, where
did you find an error on audio for hawkboard? I have tested on 4400 Hz
and it works perfect,
Any way thanks a lot, did you plan to send your patches to main line?
that would be very helpful,
However I will keep learning doing all the other patches.
Thanks
Sincerely yours
