Big fan of this sound bar I've had it for over a year and don't want to give up on it yet, here's the issue: HDMI-arc suddenly stopped working after I muted it earlier today. I've tried everything I can think of: turning off the tv, unplugging the sound bar, updating the sound bar, changing the HDMI cord, cycling through the inputs, going to all of my tv settings (note I didn't change any settings from when the device was working). Weird thing is I can connect to the LG UHD 4K tv via Bluetooth, and the tv recognizes that HDMI is connected to the tv but sound won't come on. I've been doing anything I can think of and read all the articles and manuals. I don't want to get a new sound bar yet and I'm not ready to send it in for service (mainly because it's out of warranty. (Also hard reset the bar). Any ideas would be greatly appreciated!
