G751-Series Laptops only playing sound through subwoofer. FIX??

G751 Subwoofer-only Sound Problem OFFICIAL SUPPORT THREAD
**************************************************


As the title says, all of my laptop's audio is only playing through the Subwoofer.

After a few things went wrong with cloning my old drive onto my new SSD and I ended up needing a fresh install of windows 8.1 x64 Pro - I've now gotten my computer to it's previous state, and I've transferred my files over + downloaded and installed all drivers from the ASUS G751JT support page. (Including the audio driver: "Audio_Realtek_Win81_64_VER6017335")

Thing is, after doing a speaker test now - finally in a place where I can hear them 100%, unlike the mall where I originally tested them - the sound is distinctly coming from only the subwoofer. If I make any level (Left/Right Volume) changes to the center/front/rear/subwoofer in the audio settings, only "front" makes any difference.

It makes the ONLY difference. (See: 0 = NO SOUND -> 100 = SOUND) Levels change completely normally when using headphones.



When I plug in the headphones, this screen pops up - if I go back to its settings, and select a 5.1 surround sound setting for my options, it says I have no side speakers. When I run the test and it lights up the speakers in the image while playing a sound on them, the results are the following:

• Left & Right Channels play through Subwoofer
  
• All other channels (Center, Rear Left & Right, Subwoofer) fail and do not play a sound. (Though the ambient noise of it failing to play a sound can still be heard from the subwoofer)
  

Before you recommend it, deselecting "Swap Center / Subwoofer Output" does nothing.

.... What do I do?

Marshall just sent you my Realtek Dump. Also having sound come thru the subwoofer only. Cloned OS to SSD then this happened. Worked fine when first bought it. ASUS G751JT-CH71.

Is there also a way to add USB/DVD to boot options in the BIOS? Mine seems to only show 1 boot option.

From what I could tell when I tested mine upon reception, all my speakers worked fine before cloning/reinstalling my OS as well.

This means a lot because it shows that people are getting this issue both out of the box as well as after installing the site drivers on a fresh install.

Yeah. You know where I can get an image of the Recovery Partition or something to restore it to factory settings? My brother wiped the HDD when he cloned the OS to SSD. I just want to try reverting back to just using the HDD like it was first bought to see if the speaker issue will still be the same.

Alas, no - I have no idea. I've long since settled on a fresh install.

In other news, I've moved this thread to a more updated - hopefully more helpful...

NEW THREAD.
