Connect the BD player to the TV directly again. Go into the audio menu of the player and try changing the settings. It may not be set to output audio via HDMI. If you get sound then now you knowt the player is working.
If the TV and soundbar both have HDMI-ARC and you have plugged the soundbar HDMI out to the HDMI-ARC input on the TV then you have to go into the TV menu and turn ARC on. You may also have to turn the TV speakers off and change the audio type. You also have to select HDMI-ARC as your source in the soundbar.
If they don't both have ARC then you can use the optical connection. It would require the similar set up as the ARC.
