G751 Imbalanced Sound Problem OFFICIAL SUPPORT THREAD (thread closed)

[BRSxIgnition]

I've created this thread to condense the information we've gathered on this issue over the course of the old thread, which can be found here.

Current Fix Status:
Fix Here: https://rog.asus.com/forum/showthread.php?57462-G751-Imbalanced-Sound-Problem-FIX-IS-OUT!

Current Probable Issue Diagnosis:
Regular Signal instead of LFE (Low Frequency Effects) Signal to Subwoofer

Description (In different states):

Installed Drivers (Main Issue):

All speakers "working", but WITH massive imbalance issue.Sub greatly overshadows L/R Speakers & also distorts at volumes above 35%. Can hear sound very faintly coming from L/R speakers with ear pressed up against them.

Uninstalled Drivers (Temporary Fix):

Subwoofer (Only) is default playback device, with L/R Speakers being listed as a separate playback device. Left and Right Speakers working at full volume when selected as default playback device, with no sound
coming from subwoofer. Subwoofer can play audio when selected as default device, but distorts at volume levels above 35%, and does not work in conjunction with rear speakers in this configuration. (Either/Or Situation)

Reinstalled Drivers (Main Issue, Again):

Same effect as "Installed Drivers" every time. (All speakers "working", but WITH the imbalance issue. Sub greatly outpowers L/R Speakers & also distorts at volumes above 35%. Can hear sound very faintly coming from L/R speakers with ear pressed up against them.)

**NEW** Subwoofer Disabled (New Finding/Confirmation):

L/R Speakers can be heard perfectly fine when Subwoofer is disabled using the "Vbcmd_mute_int_woofer" Mute.exe file provided by MarshallR@ASUS on the ROG Forums. Cannot comment on volume level, but volume seems to scale fine without the subwoofer to overshadow it. This confirms the situation is a software issue, and all speakers are physically fine.

This issue is known to arise both brand new "out of box" units as well as on units where the OS has been cloned or reinstalled on a new drive and the ASUS Support Site drivers have been used. All G751 Models can have this issue.

Temporary Fixes:
As mentioned in the description, the speakers still work fine, proving that the issue is Software, not Hardware-related.

To get your Left & Right back speakers working correctly, follow the temporary fix guides below.

**NEW** TEMPORARY FIX - DISABLE SUBWOOFER:

• Download and extract this RAR file.
  
• Make sure you have the ASUS G751 Realtek Drivers installed. You can find them here.
  
• Unzip Vbcmd_mute_int_woofer tool, and run Mute.exe.
  
• If it returns a "Success!" message, your subwoofer should now be disabled.
  
• If you ever need to enable your subwoofer again (when a fix is issued), simply unzip Vbcmd_unmute_int_woofer and run Unmute.exe.
  
• Viola.
  

Enjoy your tinny-back speakers with no sub until we get a fix from ASUS. Until then, keep checking in here for updates, and let us know if you find anything!

Edit by cl-Albert 2/5/15: Very late thanks for looking into this and apologies for the delay, BRSxIgnition.
The new *.7432 G751 audio driver has finally been released, so this thread has been closed (to avoid 2 competing threads) and a new thread started.
If anybody is interested, please post your testing results or comments about this new audio driver at the post below. Thanks!

Oh my God guys just buy a pair of headphones. If you can afford this laptop you can surely afford a pair of decent headphones. Once you go headphones you'll never go back.

I'm 100% sure that everyone in this thread has good set of headphones. We want our speakers to work also though because sometimes they are needed.

If you're growing weary of the complaints about the speaker problems of this device, I'd suggest you stay out of this thread. We don't need multiple imbeciles telling us to "just buy a pair of headphones."

I'm not even part of this thread anymore and I agree.

I own multiple pairs of headphones, everything from earpods to ATH-M50's and a few gaming headsets - but would I be able to share the sound with my friends if I used them? NO. Headphones are for personal audio, not shared audio.

Such a close minded response helps nobody.

On another note, I should be getting my new Phanteks Enthoo EVOLV (case) gaming PC within the next 10 days, and coupled with my new ASUS TP300 - WITH WORKING AUDIO! - I have all my needs covered.

I wish you guys all the best, you all deserve better than this.

Will you still be updating your OP if new developments turn up or should I try to keep it updated? (Not making any guarantees but I will try)

I still stop by now and again, and I'll try my best to keep it updated.

If it ever becomes a pain for me, or a fix doesn't look immenent, I'll leave it for you or someone else at that point.

the subwoofer works on mine, but makes some vibrations >> so I disabled my subwoofer by the software posted in the first page in this thread >> after disabling the subwoofer the sound became less loud >> so I enabled it again
is this normal ? is enabling the subwoofer hurt it ?

I am so sorry that my first ever post on here would have to be about this, but I have been experiencing the same issue ever since I got my G751 back in December. I figured I would drop by and voice my concern just for statistical purposes. I hope ASUS knows that there are quite a lot of people experiencing this problem. A friend of mine got a G751 as well and his sub-woofer also produces some metallic sounds at times.

[Boaz_Beatz]

same here vibration from the mouse pointers

[xamoel]

Metallic sounds for me as well, nearly no sounds from the back. Waiting for a fix!

+1. My old qosmio x770 is showing how the sound is played to my new G751.
