I couldn’t find the sound driver, please help me.

I just wanted to post a little message to thank everyone who helped solve this topic!!
I had been struggling with my problem for 3 days, I really thought I would never be able to resolve it.
I even bought new speakers thinking that was where the problem was coming from! And the drivers were nowhere to be found except on your site. Thank you so much, it works perfectly now!!
You can't imagine how happy I am to have solved the problem; thanks again.
