Hi. I'm having the same issues as everyone here. Bought the streambar 12/21. Was fine for several weeks but then started crackling & distortion from left side speaker. Tried all the suggestions. No help. Has been getting worse.
Mine is also having this issue. Started a few weeks back. Replaced the HDMI, factory reset, sound settings reset, power cycled it. Nothing helps. Serial number is YL00EC771701. Software version 11.0.0. Build 4193-95. Device ID 2A10AE771701.
