Is it similar to the reason why there is a delay between dab & fm radio?
Yeah, I'm still a bit stumped by this one. Could be:
1) There's an inherent delay with bluetooth audio, possibly for caching purposes to avoid buffering, but because there's no video reference signal when you're using your phone or a bluetooth speaker for music or whatever, you don't notice it.
The only thing here is that the delay on my mate's TV/speaker setup was at least 4 seconds, and presumably, you'd notice that on a bluetooth phone call. Suppose voice calls could be a lower data rate because it's only a fairly small bandwidth for voice frequencies, and therefore less caching involved, so less noticeable.
2) Any delay between the audio & video signal is noticeable. I've never used a bluetooth soundbar on a TV, but you'd have to presume there's ways of addressing sync issues automatically. Or do you always need to use a sync adjust feature on the TV to delay the video signal a few seconds to compensate for the inherent delay with BT audio? Would seem a bit of a major design flaw with BT enabled soundbars if there's no means to auto-adjust.
Anyway, this is continuing to annoy me, and although I've told him to get some line out cables and be done with it, I will be unable to relax until I have an answer.
