Customer Reviews for Sony HT-S400 2.1 Soundbar with Powerful Wireless Subwoofer
I am using the toslink optical connection just as I did with the old soundbar - and was very very surprised to hear a significant lag in the audio between the bar and TV! It introduces a quiet intrusive echo effect - the only way which can be resolved is to turn the TV volume to zero. While some TV's may have options to increase the audio latency to match an external soundbar mine does not.
This issue did not exist on my ancient cheap soundbar that it was replacing. The old soundbar has no discernible lag.
The issue is easy enough to avoid - just mute the TV. But still, it was unexpected - could the latency issues be something Sony could improve with a firmware update? Updating from Canadian firmware 1.114 to 1.188 made no difference. (I mention "Canadian version" because it seems other countries have a higher firmware version number 1.195 but release date is the same - SONY, this seems very odd.)
