My del latitude 3440 sound had stop working since last year after connecting it to an external speaker listening to music. I tried system restore right after the moment it went off but does not do anything. I tried installing the audio drivers but still can't. I was assuming that it might be the hardware problem but don't really sure about it. Can anyone please remove the burden from me.
Do you hear the Windows start-up tone when it's loading? Can you run the on-board diagnostics <F12> and capture any error message or codes.
Please click my DELL-username and send me a Private Message with the Dell Service Tag number and your email address, so that we can check on the configurations.
Hello. Run the ePSA audio test.
If you don't hear the test tones that means the audio is dead.
If you do hear the tones, that means the speakers still work, but there could be other issues with the audio hardware.
