USB Audio Reference Design: How can I get the Mute-Status fr

[fabib]

Hi,

I implemented a function that reads an input to set the Mute-Status by using UserReadHIDButtons. The Mute-Info in the Windows mixer is updated sucesfully if the Mute-Button on the device is pressed.

But how can I get the info if the Mute Button in the Windows mixer is pressed?

Regards,
Fabian

You should be able to communicate with the HID class driver in the opposite direction by declaring an OUT endpoint in addition to the standard IN endpoint with usages from some of the indication-providing pages such as LED (8) or consumer (12).
