There is nothing specific to Bluetooth in our desktop software basically, any regular audio input or output that Windows recognizes GoToMeeting should be able to use. Another customer last week reported a similar issue, we went into his advanced audio settings and reduced the levels of his Bluetooth devices and they began working. I am going to ask our team to investigate this issue further, now that we have a 2nd report.
Right click on the speaker icon in your System tray and select Playback Devices, then select your Bluetooth device and click on Properties. There will be a Levels tab displayed, try dragging that down to 50%.
I am using the beatsx bluetooth headset.
I can get it to work for audio, but it will not work as a mic.
The headset works with all other voice/video applications like Skype.
