As suggested by Ëwen, kinldy check the video and audio drivers. If they are not updated, kinldy update them from the manufacturers webiste.
In case there are any In Built Diagnostics provided by OEM, try running the audio diagnostics.
If this issue started occurring after doing some recent software changes on your computer, then I would suggest you to restore your system back to a date when it was working fine. System Restore will affect Windows system files, programs, and registry settings only.
Let me know if that fixes the issue
Thanks & Regards
