Audio cutting out

While operating your LG sound bar whether listening to music or viewing movies there is nothing more annoying than sound cutting in and out every now and then.

There are two issues that could be root cause of such situation. It can be caused by Bluetooth interference or sound bar is operating without a rear satellite kit while signal source is configured to deliver true surround sound. There is no solution to the former other than hardwiring at times of heavy Bluetooth device traffic in the vicinity. As for the latter, should it be the case, there is a software update to fix the issue.


First, you’ll need to determine whether it’s a Bluetooth interference scenario or not.

Are you streaming music or a movie to the sound bar via Bluetooth when the audio cuts out? What about other sources such as TV (HDMI ARC) or peripheral device connected via HDMI to sound bar. Are you experiencing the same audio cutting out dilemma?

If no to the second question, it’s a Bluetooth interference situation.

If yes, then you will need to update the software version of the sound bar.

 Software Update

The reason software version of the sound bar requires updating is because the unit is configured to deliver surround sound according to the source being played. However, unfortunately, there is no wireless rear satellite speaker kit connected to this audio system which is causing to react by audio cutting out every now and then.

SJ5Y update:


Once the sound bar has completed the update and shut itself “off” it is then safe to power it back “on” and enjoy the sound.
