Is Gather switching your audio inputs every time you switch tabs? Or are you able to hear others but they can't hear you? Huge changes in audio quality when you mute and unmute? If you're using a bluetooth headset, this article may provide some clarity.  

Bluetooth Profiles

Every Bluetooth accessory comes with a built-in profile, which is a package of software that tells the device how to "treat" the accessory. Some devices will automatically sense a Bluetooth accessory, and then apply an incorrect profile to them from their own library. 

If you find that you can only hear others but they can't hear you, the cause may be your Bluetooth profile. Bluetooth A2DP, a type of Bluetooth profile, does not allow for stereo audio plus microphone at the same time.

Many Bluetooth headsets, widely produced before 2018, use Bluetooth A2DP. Some mobile devices will accommodate the limitation of A2DP by switching between sending microphone inputs and receiving stereo audio input quickly and automatically. Some devices (computers, tablets, etc.) do not support the automatic switching of inputs and outputs required by A2DP for a smooth experience. 

One solution would be to use a separate microphone if you wish to use Bluetooth headphones. 

Test Inputs

When you select your input (mic) in Gather, your computer will generate a list of what it views as available. In the gif below of the Check Your Hair screen, the drop-down menus show several options for the same headset. Each option is a different profile that can apply to the device. 

(1) Before you enter a Space, you can try different input and output combinations.

Finding the right combination that works for you may take some trial and error.
