This should be as easy as setting HID_CONTROLS to 1 and then coding in the buttons to set the correct bits of the HID report

CONTROL Windows Volume

I can control the volume in Win10, but when they are not synchronized. For example, the windows volume can't be raised if the xmos' volume reach the maximum. Just like xmos volume is 100, but windows volume is 80. How about the reason?

I would check that if you simply set hidData[0] = 0x8 without any other logic the volume is increased as you expect
