I think if you use toslink most TVs will still play audio audibly while putting signal out to your connector. If you use headphone jack connection, then some will and some won’t play audio out the builtin speakers. But I wouldn’t be surprised if it cuts out. I think the sound over connector or Roger On seems better than BT – more solid a connection, and your battery in your BT master HA will last longer
using the connector or a Roger Mic than using BT.
