I'm trying to hookup the bose cinemate speaker system to an insignia tv, polaroid dvd player and at&t uverse cable box. I get speaker sound when watching cable, but when switching to the dvd, there's no speaker sound. is this a connection problem or problem with the programming?

How many audio input does your cinemate have? in case you only have one, you need an audio video switcher. a sample picture of what you need is on this link > http://electronicsusa.com/svs14.html find what you need, that is just for you to see what its look like. another thing is check you dvd if it has a line input - meaning it allows you to connect another source into your dvd such as vhs, cd, mp3. for for audio video - you need 3 wires (video/audio left-right), for stereo audio - 2 wires (left/right connection). some dvd player call it as line1 and line2 inputs. if you have it then you should be ok. 3rd approach, a simple audio mixer with minimum 3 inputs and 1 ouput is enough. note: last thing, check your connection interface for connection compatibility if you plan to buy audio video switcher or audio mixer. hope this help. regards, cebuwano
