Hi,
heh heh yeah it is not that obvious coz sometimes people just forget the volume on the tv. Unfortunately for me that is not the case my volume was turned on to 100 incase of anything. i dont have another HDMI port and i dont have another HDMI cable but actually i will try and test it somewhere else to see if the problem is the tv. I know the volume works on the tv though. just not through hdmi.
