Sony Bravia 4k no audio after troubleshooting. Have switched cable boxes to isolate as a TV issue, and tested with speakers and headphone ports with no audio from TV. Also ran all audio settings.

It's not compatible with the Phillips DVD player. We had the same problem with our old DVD player, something about reading it.

Like above, use an optical connection (need fiber optic cable) or a coaxial connection (single RCA cable). HDMI might also work, but I personally haven't checked. Connect the audio outs from the cable box to the audio ins on the home theater. The TV will only need a video connection from the cable box, as well as one from the home theater (for DVDs, onscreen menus).

This discussion can help you set up the universal remote.

As long as you continue to have both HDMI and optical outputs connected at same time from the cable box, it will probably always choose the default as HDMI. If you do not want to change any connections then the best thing to do in this case is to always leave the cable box turned on. Otherwise, disconnect the HDMI and connect it to the TV by component video.

Check the connections between the cable box and the TV. If you are using scart check the connector is in squarely if using rgb or composite you need a separate audio connection using the red and white phon sockets.

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.
