Samsung QLED 4k and jbl 3.1 .. when changing channel or adverts come on the soundbar shows either PCM or DOLBY AND the sound is delayed then it come in about 1/2 second later. There is sometimes a slight popping sound from the subwoofer. Is there a setting on the tv that I have missed
How do you have the system set up? Also, what is your current firmware version of your TV and model number?
I have the soundbar connected by HDMI to the HDMI (ARC) on the TV using the HDMI cable that came with the soundbar. The TV is QA65Q60RAWXXY it is a Q60R QLED 4K model bought Decemeber 2019 as was the JBL 3.1 soundbar. I have checked for firmware on the TV and it says that it is the latest version and no update is available. I have doe nthe same on the soundbar and that also is running the latest firmware.
I have an older Samsung TV and the same problem occurs on that also with the soundbar.
Thanks for your interest.
What is the model code for the soundbar?
I recommend reaching out to the manufacturer of the soundbar. This may be a compatibility issue.
