i recently lost the audio on my computer, the audio shortcut on the taskbar is crossed and if I click it, it will automatically launch the troubleshooting, which detects the problem and asks me to restart. when i do, there is no change and the process is repeated.
I entered device manager and sound, video and game controllers did not appear, when i showed the hidden ones, they appeared, all of them had the message " not connected" and (Code 45).
I then uninstalled all of the drivers of sound in there and restarted, the drivers were not re-installed. then i entered the dell website and downloaded the audio driver they have in there, installed and nothing happened.
the problem is still the same and now i can not even find the drivers
Other people have been reporting problems like yours that seem to be related to BIOS (on other models but they have rhe same BIOS as yours) Try downgrading to BIOS 01.06.00 - A05 and see if that helps..
