5 Reasons Why Does The LG Soundbar Keep Switching Inputs!
As mentioned, there can be numerous reasons why your LG soundbar might act strange. However, you don’t need to worry too much about it because we’re here to resolve the issues once and for all.
01. Problem With The HDMI Leads Of LG Soundbar Will Shuffle The Input:
A faulty HDMI cable is one of the main reasons the soundbar is getting connected to another device or input.
That’s why you guys have to check the compatibility of the leads first. And inspect whether you’ve installed the HDMI correctly into the ports.
For example, If your LG soundbar is connected to HDMI input 1 on your TV, but your TV is currently on HDMI input 2, then whenever you turn on your TV, it will send a signal to your soundbar to switch to HDMI input 2.
This can cause the soundbar to switch inputs unexpectedly, and you may not hear any sound if there is no audio coming from the new input. Consequently, your LG soundbar might turn off as well!
Solution:
To resolve this problem, Check out your LG soundbar manual and make sure which audio input ports you need to use. Try to keep the HDMI In cable into your TV/ LED and HDMI Out in the Soundbar.
Also, ensure that the wires are inserted strongly and are fastened properly into the slots.
02. CEC Bug In TV / LED
Another matter of great concern is the error in the CEC settings of the TV connected to the LG Soundbar.
Generally, CEC (Consumer Electronics Control) is a feature that allows devices to communicate and send/receive signals to each other over an HDMI cable.
So, When a CEC bug is in the system, the devices may lose communication with each other. As a result, the soundbar will switch to a different input in an attempt to re-establish its connection.
Solution:
This problem can be due to defected HDMI cable of the TV. So, find out the fault and simply replace it with a new one.
You can also check for Updates in the system. It might be happening to upgrade the features of your devices. So, grab the manual and go for it.
You can head over to forums where many users are discussing LG soundbar audio troubleshooting and get a better picture.
03. Open BT (BlueTooth) on Your Soundbar
Have you checked the BlueTooth connection to your LG soundbar? It might seem like a small error on your part but it can definitely cause the audio input switching issues.
When the Bluetooth of your soundbar is open, it means the device is scanning to connect with another specific device that also has an open BT.
And eventually, they get connected even if the soundbar is in optical cable pairing to the TV or speakers.
So, you definitely need to know how to turn off BT on LG soundbars. Otherwise, you’ll face this problem every now and then!
Solution:
The best way to keep your device secure and not get paired with other devices is to simply turn off the BT on your LG soundbar. Obviously, that’s only applicable if you’re using HDMI or optical cable for connection.
This is possible by holding the “Auto Power On” button on the Soundbar Remote for almost 2-3 seconds.
As soon as the Red LED on the display window of the LG Soundbar starts to blink, release the button.
Also, make sure the TV/LED is connected properly to the soundbar.
04. Outdated Firmware
When the Firmware is outdated, it may be unable to recognize certain input signals from the soundbar’s hardware. Or, it can happen to the device you’re trying to connect with the LG soundbar.
So, it can result in the auto-switching of the input or not responding at all when you try to switch inputs.
Solution:
To make sure this problem is not causing the constant input switching, make sure you have the latest firmware on both devices. You can easily find the firmware updates on the manufacturer’s website.
Search for your particular model and download the software. You can also update it from your Settings.
