Bose Soundbar 700 audio sync problems with TV
Ever since i've had my Bose 700 soundbar, i've had lip syncing problems with my sony smart TV, whereby the sound is delayed compared to the picture. I rarely get the problem with free to air TV, but get it when i stream, eg netflix. I suspect this may be due to the 5.1 channels that need to be processed from netflix, as opposed to 2 channel from regular tv. The audio is delayed compared to the picture, so they audio delay setting in bose music app is not helpful, as it delays the sound even more. I do not have this problem if I use the tv speakers instead of the soundbar.
In my Sony TV audio output settings, I have options of PCM, auto 1 and auto 2. If i select PCM, the problem seems to be better (but not perfect).
My questions are:
1. Has anyone else experienced this, and is there any advice to fix this?
2. By setting my tv audio output to pcm instead of auto 1/2, does this mean i'm not sending the best audio format to the soundbar, and thus not getting the kind of sound quality that the bose was designed for?
