I have just brought a hw-e450 for my LG 37LF2510 tv and LG BD670 blu-ray player, the sound is crisp and powerful, but I cannot get any sound on tv. Sound bar does work and you can hear the sound from BD/DVD, but if you turn down the volume of the hw-e450 anything sounds on the tv speakers.
LG BD670 --> HDMI IN --> HW-E450 --> HDMI OUT --> LG 37LF2510
Both HDMI cables are 1.4 version, is this a compatibility issue?.
Please help me!
