Audio problem in my mobo

[vasanthancs]

My mobo Asus M4a78T-E has up to 7.1 onboard Audio support . Sound works fine with 2 channel . But there is no output for rear , center and side speaker . Only green socket in the back panel works .... No output from red , blue and orange pins when i change the mode to 4 channel or 6 channel or 8 channel support in VIA Audio Deck .

What will be the issue ?

Software issue. otherwise mobo is gone.

I use ac97 codecs and motherboards, never had single problem. 2ch, 4 or 6 worked every time in every setting.

Uninstall audio drivers and download latest drivers from Asus website for your mobo.
