A:Answer If your soundbar connects to your TV via HDMI, it's possible that it can control the soundbar volume through CEC. It's also possible to program this remote to control your soundbar through IR. This remote does support programming it to control some devices, but I have no idea if TCL is a supported brand. A TCL TV, I would say yes. But the soundbar uses different IR codes from their TVs, so the Shield remote would need to support both sets of codes.
