Precision 7910, No sound from front/rear jacks

Hi JoeJoe88,

Thank you for writing to the Dell Community Forum.

Please update the latest BIOS install the chipset driver Intel Management Engine Components Installer Driver and Realtek HD Audio Driver http://dell.to/1TPmL5n. Check if the speakers / headphone work on other device.

Kindly get back if there are any further queries.

Thanks for helping DI.

Yes the speakers work on other devices.  I have it on a SB card in this machine now and they work off that..  They would not work on the front or rear jacks.  My webcam microphone is recognized via the rear USB and work fine.

I downloaded and installed all the updates, (only the Intel were needed via detect but reinstalled anyway).

Activated Realtek devices and tried to configure, no luck.  This machine shipped to original owner with an SB card.  Could builders have disabled jacks before shipping?  No internal speaker.

Device manager shows all sound devices working fine, but does not show the chip as I think it did on the 7400 (rip).

Thanks for any help, much appreciated.

Other than the sound, absolutely love the machine.

Joe

Hi Joe,

Please go to the BIOS> System configuration> Audio and ensure the integrated audio controller is enabled. If it is enabled already, you could try reinstalling the operating system.

Note: Do a backup of all important data, before reinstalling the operating system and the programs needs to be reinstalled.

Hi Di,

Ran the extended BIOS test,  no errors, but no sound output.  Ran Dell nline diag ad dxdiag, all say Realtek was ok. 

Checked device manager and all appear to be working properly.

With that being the case, how does a reinstall of the OS make any sense?  My discussion with the Dell techline was short as this is a lease return and I cannot transfer ownership, but in their mind it was a jack issue, which is why I asked if it was related to the sound card.

If there is a plausible reason, would a repair install work?

Joe

PS, first thing I did was check BIOS when I ran extended test
