Hello there, Shawn. Thank you for reaching out about your LG S70TR Sound Bar. We understand how concerning it can be to hear unexpected crackling sounds. This issue may be related to wireless interference, loose connections, or the system’s settings. Here are some steps you can try: Ensure all cables are securely connected. Reduce potential interference by placing the sound bar and subwoofer away from other wireless devices, such as routers. Adjust the audio settings to test different modes, as this can sometimes resolve sound irregularities. If the issue persists, we recommend contacting LG’s support team directly through social media at @LGUSSupport for personalized assistance. Since your unit is under a year old, it may still be within the warranty period, and our team can help explore repair or replacement options.
