-What type of 790 form factor (mini-tower, desktop, small form factor, ultra small)?
-When you replaced the hardware (and both front and back jacks worked okay), did you do any type of Windows updates? Did the jacks works after loading RealTek drivers?

-In your device manager (run box type devmgmt.msc) are there any warnings?
Sounds like you did a lot to troubleshoot this. I ran into interesting issues with Optiplex 790 and also 9020 where some Intel display drivers from Windows update are coupled with audio functionality (I guess to power some built in audio features in displays). Also does the 790 have any expansion cards for video or other media attached?

I am currently working with a Dell Optiplex 790 and just recently upgraded to windows 10.
I am unable to get sound to come our of any speakers. The sound devices section lists: ATAPI Internal connector High definition audio device Sound only seems to come out of the ATAPI Internal connector which is a single speaker inside the computer. If I set the 'High definition audio device' to default it thinks sound is coming out but nothing is played through the speakers, headphones etc. Both the front panel and rear panel refuse to output sound though they are able to recognize when something is plugged into them. Has anyone else run into this issue? I have run out of ideas. According to the dell website when I run the service tag I have a Realtek ALC269. At this time dell has no plans to support windows 10. Any help would be greatly appreciated. Comments are closed.
