Question TCL speaker/TV audio issue

[jone4646]

I have a 55’ TCL tv and a TCL speaker without a subwoofer (alto 8 maybe) that are both around 5 years old. For the last few months while watching anything the speaker will randomly go silent for a couple seconds and flash “Dolby Atmos” across the speaker screen. Extremely distracting and annoying. Anyone know if this is a connection issue? Or if the speaker or TV just needs to be replaced (I don’t want to replace one if the problem is the other). The audio connection I’m using is HDMI in arc3. I know neither the speaker nor TV are high end.
