Weak left channel

SOURCE: no surround sound

So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck

Check to see if your audio header is hooked up correctly on your motherboard if your using the front panel audio, if your not using the front panel audio then make sure the audio header has the two jumpers on them!! Check your mother board manual for proper procedure to hook up! If that still doesn't help then it could be a faulty sound device! You can fix this buy purchasing a new sound card! hope this helps! regards, babb

I have exactly the same problem but found two work arounds, either one that I am completely satisfied. 1. unplug and replug the AC.
2. I have a subwoofer, when I plug the subwoofer cable half way in, the sounds of the base speak goes back to normal (but not all the way in)

were you able to solve this one ? I have the same problem with mine. The only way to clear the lack of sound in one of the speakers is to rotate the input knob !!
