I have a Toshiba TY-WSB600 sound bar with a wireless subwoofer that I am trying to connect to my Vizio V505-G9 TV. I have connected the sound bar to the TV using a HDMI cable, and can get sound out of the sound bar, and can control it with the TV remote. My problem is that I can't get the sound bar to pair with the wireless subwoofer. It does not automatically pair when turned on, and I have tried the manual pairing as outlined in the instructions using the Pair button on the rear of the subwoofer without success. The sound bar and subwoofer are just a few feet apart, but won't pair. Any suggestions on what to try next would be SO appreciated - I have gone thru the pairing instructions dozens of times, unplugged everything, etc. Do I need to use a digital audio fiber optical cable instead so everything works properly, or is this an issue between the sound bar and the subwoofer? I do have the TV signal output set to PCM. I appreciate your help.
