After I've sent back the previous soundbar due to the sound skipping (and otherwise not liking the quality), my Philips 55OLED706 (fully updated) produces the same issue on a different (make & model) soundbar, so I'm guessing the fault is with the TV instead of the bar itself.
Symptom: the sound sometimes skips a couple (~3-7) seconds but comes back without any intervention.
Both bars were connected through eARC.
Otherwise both bars were perfectly OK when casting or playing through BT.
Any ideas what could cause this?
