Hi. I'm David, and I'm happy to help you.
Please clarify the following:
- Just to confirm: Does the headphone have a standard audio connector (Jack connector) or a USB connector, or is it connected via Bluetooth?
- Is there a red circle with an "X" over the speaker icon next to the clock? (When you hover your mouse over it, does it say "No audio output device is installed"?)
Also, share a screenshot of your system information.
- Press "Windows + R", type
msinfo32and press Enter.
Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.
Looking forward to your reply.
