Thank you for posting on HP Forums,
Riddle_Decipher is at your service.
As I understand there's a grey hp audio box on desktop can not delete or move,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Have you attempted to reinstall or update the audio drivers to resolve the issue?
If you haven't, let's start with that, Click here to find and install the latest drivers for your audio card, BIOS & the Chip-set drivers.
If the issue persists, please capture a screenshot of the grey box and reply back,
So that we know exactly what we are dealing with and resolve it accordingly.
Let me know how that pans out
feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon,
followed by clicking on 'Accepted as Solution' as it would help the community gain more knowledge,
And Have a great day Ahead!
