no rear surround

moonbeam · 30 Dec 2012

Hello my names Craig im having a strange issue & im trying to narrow down where the problem is motherboard or some glitch in the drivers

motherboard Asus p9x79 pro

running 5.1 ac3
left & right , center sub woofer work
Rear surround has just stopped working for no reason i do no understand why

i change the plugs around in back on motherboard & it only seems the rear surround plug port is not working . i plug the speaker in & realtek notices that a plug has been pushed in . i test the sound & rears still dont work .

went into playback devices & came across something wierd in picture below shows two 5.1 so i decided i would reformat the computer & see if i still have problem

okay so computer has been reformated check the settings the two 5.1 surround has gone but still no rear surround .

any suggest please I really love my sound

kind regards
Craig

First question, are you using the correct ASUS supplied sound driver? If not, that is the first step. In most cases the Vendor supplied sound driver is preferred. Non-Vendor drivers can either not work or not work correctly and that includes the generic (basic function) HD Audio Codec that Windows will install.

yep up to date on all drivers double checked them !

That is the same display I get on my RealTek. I don't have 5.1 so I can't test it. I can also set it up in the RealTek Control panel, listed in the control panel/Hardware and sound. If you have RealTek, check your control panel.

Are you testing with a 5.1 FILM?

Stereo music mp3's etc are just 2 channels

There are tick/check (for you USA's) boxes which give false 5.1 on muzac files by just multiplying them
ie copying the original two channels to a further two/four.

Check yer tick boxes in the sound menus/sub-menus!

i tested a 5.1 movie & found that there might actualy be sound but its extremely soft ,even when i turn the volume button up

There are numerous volume adjusters hidden away in the setup menus.

The rear spkrs are always set softer than the front.
Check the sound icon volume slider + Realtek icon
- plus the others hidden in the sub menus.

Are your cables back in original position?

Start at beginning setup as 2.1/stereo > Test (volume loudness back?)
Reboot pc

Then try 5.1 setup

If you have full range spkrs make sure you adjust it as you go thru spkr setup menus.

Make sure windows media player slider hasn't moved/ditto Media Centre I usually leave these all at 50% default

there all fine its something else causing it =(

Try resetting yer Bios - take soundcard out first

Only other thing I can think of is your spkr AMP isn't connected to electric or has died.

The residual low sound is from inbuilt motherboard weak amplification?
