Hello, thank you for reaching out to Microsoft Q&A.
- Did the issue happen after the latest Windows updates?
- Do you see an 'X' icon on the volume icon in the taskbar? Or may I please know the default audio output selected in the system sound settings?
Go to Start > Settings > System > Sound > Choose your default output device. (Example screenshot for your reference)
If there is no audio output device installed, we might need to reinstall the drivers.
If you see an audio output device, make sure the volume is not muted.
Let me know the results.
