Using HID to control microphone mute for a audio device

HI

I am writting the firmware of a fake "headset", and want to use HID to control the volume & mute.

But now the speaker volume & mute can work by using HID,  the microphone cannot work , for volume & mute

 I wrote the HID report descriptor according to the sepc from usb.org

Is there any example? what should  I do ? or the Windows do not supoort HID for mic control?

Thanks
