A few times since I bought it, the sound would stop working. Usually the solution, if I recall correctly, was updating the BIOS (why the sound would suddenly brick when a new BIOS came out, I do not know).
I hadn't used my computer for a couple weeks, so I did all the updates, still no sound.
I reinstalled windows, uninstalled and reinstalled the audio driver (Conexant); and installed multiple times the latest audio driver
I think the problem is the audio driver doesn't install.
The latest one from Conexant CX20722 Audio Driver is Version 220.127.116.11, A04, and my computer has 18.104.22.168. I don't see how to fix it. Also, my driver and the latest driver be the same, since the latest driver came out March 14 according to the dell website, and my driver was installed March 13. Version numbers suggest they're different but theyre so close in date...
Suffice to say I'm never going to buy a Dell again unless there's a 3+ year warranty with it. Ridiculous that basic functionality fails.
Solved! Go to Solution.
If you can, back up and install the original BIOS that was installed on your mother board chip, if all was working just fine before ALL your "Recommended," updating. Much success.
Wouldn't restoring the BIOS create other issues? There's been numerous BIOS updates classified as Urgent, and I don't want to screw anything up if new Windows versions only work with new BIOS.
It was pretty simple once I tried it - hit F2 while the computer is booting to enter the BIOS menu, and restore the defaults.
