Hello,
I am facing a similar problem. My audio sound is totally off, with or without headphones or speakers.
The other day I mistakenly deleted a driver that may be the sole sound producer sound- IDT audio. And I do not know how to re-install it. But I'm not sure if it's the only driver that produces sound on my system, as I also have AMD high definition audio.
I just need help please. Thank you.
