Most of the audio for voices comes from the center channel. Try checking to make sure that the speaker wires are connected properly both in the rear of the unit and at the speaker connection.
Also, what sound mode are you using, and are you getting any sound from the center channel?
Hi, I have recently upgraded the firmware to version 1.7 and now my HT-BD2 bluray displays firmware version S/W 100827.01_XSA on the system.
The problem I am having is that I can only hear the background music when watching a bluray movie, but can't hear the speech sound of the actors for some reason.
Do you what could be causing this issue?
