i have gigabyte ga-g31m-s2l motherboard. I installed intex tuner card. My problem is the sound is not coming from system speakers. I have to keep changing the speaker jack between system and tuner card .Also the sound is not recorded when i am recording programs. Previously i used to have gigabyte motherboard (845 chipset ) . The same tuner card worked fine with that. There i connected the output of tunercard (greenport) to the blue port of system and speaker to green port of system.There every thing was fine. But with this new Motherboard that procedure failed. what to do?
