FYI, I upgraded my RM10 today to image / firmware 1.8.1, after a successful install, the Mic sound is not passed to the controlled device, the GLKVM Mic icon shows sound activity, but the controlled device shows no sound activity and is silent.
I tried the following: -
Checked the controlled device (windows 11) sound options
Uninstalled the Comet Mic device from controlled device and re-installed
Rebooted both the controlled device and RM10
Disabled and enabled the mic option on the RM10
Changed the controlled device settings for the Mic and then back to the comet Mic
Changed the Mic sensitivity settings on the controlled device
Tried opera and edge browsers
Tried Windows 11 and Linux (ubuntu)
Rolled back to firmware 1.8.0 and the mic is now working again.
