I have currently hooked my pc up to a HDTV. I have a Diamond ATI Radeon HD 4890 Graphics card with the manufacturer dvi to hdmi converter. I run one HDMI cable from the card to my sound system(Sony STR-K700 Variant), then of course from there to the tv. The picture is 100% fine my problem is with the audio. Its not that I dont have audio it's just that the output is constantly at a low volume in other words at max volume i can barely hear it. I am interested to know if anyone could help me fix this problem.
