RE: Latitude E5470 Audio controller none in BIOS

Hi lw2525,

When you say no audio controller in BIOS, are you referring to the Device Information section under System Information? If so, can you try entering the diagnostics (press and hold Fn whilst powering the system on) and running the speaker test? If there is no sound from that, it's not looking too good I'm afraid.

All I could then suggest is to try updating the BIOS:

Let us know how you get on.
