Hey, Have you tried making your microphone the default input? Here is a [url=https://www.howtogeek.com/700440/how-to-choose-your-default-microphone-on-windows-10/#:~:text=In%20the%20%E2%80%9CSettings%E2%80%9D%20window%2C,use%20as%20your%20default%20device.]guide[/url] on how to do so. I would also recommend making sure you have a input device selected for Destiny 2, to do this launch Destiny 2, then in the Windows start menu type in "Sound Mixer Options", click on that and you will see a list of applications, make sure Destiny 2 has the correct input/output.
