Strange is the only word I could come up with. I( am using an on board audio on ASUS M5A97 r2.0. Which is Realtek. For some reason the output is often only comes out of only one speaker (left). I thought that it could have been something wrong with my speakers, but I noticed that whenever I play games the sound comes from both speakers. I have also disabled the HDMI sound device for my video card, to no avail. I thought the two might have had a conflict. I tried changing various settings in Realtek control panel and Windows own sound settings, but nothing worked. I am out of ideas. Anyone know what I can do? I have a 2.1 speaker setup, for now and the sub works just fine. Thanks.
