Hi Lyndsey,
I have checked the issue, and as I understand it, please check if the headset is appearing in the sound settings. If it is showing, troubleshoot the app settings you are using. If it is not showing, please check the sound drivers on your system.
Please refer to the attached screenshot for the sound settings.
I hope this resolves the issue; if not, please let me know.
Thanks and regards,
Arvind Kumar
