Hi
I am wondering if anyone can suggest where to look to find out how to access
audio controls on a UAC2 audio device on Windows?
We have a UAC2 device that runs fine on Mac OSX using coreaudio and we can
access extension units on the device control endpoint using libusb to control
various aspects of our device.
For PC use we intend to license a commercial UAC2 standard Windows audio
driver, and we have a couple of candidates for evaluation. Although these allow
audio workstations to use our device I want to make our remote control
application send and receive data to various extension units on our hardware
(via the control endpoint 0) the same as on Mac OSX.
The question is whether there is a standard API to access these controls that
all UAC2 drivers implement the same way, or whether this is likely to vary with
each driver implementation? If there is a standard that will allow me to open
the device control endpoint and exchange data, where might I look for that
information?
I've tried googling it, but unfortunately results for UAC2 are usually swamped
with unrelated UAC issues which seem to be a hotter topic!
Thanks for any pointers..
Mike
