Welcome to HP Support Forums. A really great platform for posting all your questions and finding solutions.
I understand that you are facing audio issues on your HP x2 210 Detachable PC.
I'd like to help
I suggest you complete all the Windows updates since you just did a Factory Reset.
Select the Start button, and then go to Settings > Update & security > Windows Update, and select Check for updates.
Also download the Bios from Here
Keep me posted how it goes.
Thank you. :)
