Hi,
I hope someone will be able to help with my issue with audio lip syncing with my home surround system please? I know its a long standing problem inherent with surround systems, but I hope there is something I can do about it. Its driving me insane!
I have a Sky HD box, very recently installed, which connects to my Samsung Series 7 Smart LED TV via an HDMI cable. The audio sounds fine if I listen to it via the TV speakers; there are no lip synch issues.
I'd like to listen to the audio via the Sony STR-DB930 receiver which has surround sound speakers. The Sony receiver is connected to the Sky Box via analogue audio cables. If I do this however, there is a noticeable delay with the sound first and the video second. I think somewhere around 300ms at a guess.
Similarly with the Blu Ray player. This is also connected to the TV via HDMI and to the receiver via red and white analogue audio cables. There is also a delay.
The Sky box has an option to delay digital audio (it specifically says digital audio rather than simply audio) by up to 200ms, but I have thus far been unable to tell whether or not it makes a difference even when set to 200. Either way, the audio delay is still present - sometimes I think it is improved, sometimes I'm not sure. It could be that the delay is greater than 200ms or that the analogue audio isn't being delayed by the 'digital' audio delay set on the Sky box.
I've been thinking of solutions.
One would be something like the Felston DD540, a device I assume goes between the source and the Receiver and adds a delay. However, that would be an expensive option.
I've also read that optical digital audio cables might have a delay inherent in the way they transmit data. Perhaps simply switching from analogue audio cables between the Sky box and the receiver to digital would add a bit of a delay to the audio and help with the lip synch problem? Even if not, digital optical cables are better than analogue right? True 5.1 and all that.
Lastly, I wonder if it would be possible to run one optical (or analogue I suppose) audio cable from the TV to the receiver instead of from the Sky and Blu Ray box. So, rather than having audio cables connecting each to the receiver, why not keep the HDMI cables to the TV and then just have one audio cable to the receiver from the TV? Something tells me that wouldn't work, although I don't know why. There is an option on the TV to use external speakers. Would this be possible and, if so, would that help eliminate the lip synch problem?
Any advice greatly appreciated.
Thanks
Matt
