I Used GeForce GT 220 GPU on my Toshiba laptop and now i am trying to get the 5.1 audio output with the help of HDMI display connector of the GPU. This GPU presents on my laptop and i make connection with the Toshiba HDTV with using this HDMI port. NOW when i try to play any files on it and check the audio signal. It only gives 2.0 and not more than that. I try a lot but couldn't find any way that works to fix this complex issue. Thanks for any help to fix this sound problem.
