Bose 700 headphones mutes all other audio when "communicating" (e.g. using Skype or Discord)
When my headphones are connected by Bluetooth to my PC, they refuse to play any audio (such as Youtube videos) while talking on either Skype or Discord. This is not because of the Communications tab of the sound control panel, because I have set it to "Do nothing" when "Windows detects communications activity." This is likely not because of Skype or Discord as another thread ended on, because it happens with any communication. It uniquely has to do with how Windows treats the difference between the "Bose NC 700 HP Hands-Free AG Audio" device, which is set to the "Default Communication Device" in the sound control panel, and the "Bose NC 700 HP Stereo" device, which is set to the "Default Device" in the sound control panel. It works perfectly fine when I use it in wired mode, as the "Default Device" in the sound control panel is "Realtek High Definition Audio." I have no idea how to fix this. Please help.
I have updated my headphones to the latest version using the Bose Music app. I am on Windows 10 Version 1903 for x64.
