My USB headsets have mute, volume up and volume down buttons exposed with an HID interface. When I use them with Ubuntu/PulseAudio nothing happens. Wondering if this is not supported at all, if my config is broken or if a manual setup is required as described in [1] - a basic workaround to link keycodes and alsamixer. If PulseAudio had this information it could do a much better job. Thoughts? Thanks, -Pierre [1] https://help.ubuntu.com/community/PlantronicsUSBHeadsetControls
