Hi friends,
I am using an Ez USB board to prepare a demo audio project.I have a requirement
to increase the volume of my recorded wav file depending on the buttons on my
kit, ie vol up and down. The enumeration is ok now, and the firmware keeps on
pumping the hard coded sine tone values to the host.So, after selecting th
enumerated board as a recording device, I can record the sine tone. Now, i want
to change the volume of the sine tone using my boards f1, f2 push buttons. I
thought I could use the control end point with Vol up, vol down for that. But
it does not seem to work.
On going through microsoft documentation
,http://www.microsoft.com/hwdev/tech/input/audctrl.asp
it seems that audio controls are supported for play back only, not recording..
Am i correct in this assumption? any way to implement this without using the
audio controls
Thanks a lot, for your kind suggestions and comments ...
Ajai James
