Review title is Will not work with Optical Signals from Some TV brands [SEP] The original TVlink I did not have a optical input, so they added a crippled one to the Tvlink II.  The issue is that virtually all modern TV sets output audio thru a optical connector and are set to Dolby Digital 5.1 by default.  The Tvlink II will not respond to a optical signal with Dolby Digital.  Why??  The Resound Reunite works fine with a Dolby Digital optical signal.<br /><br />So, if your TV allows it, you can go into setup and muck around to change the audio decoding to PCM in order to make the TV link II work.  Unfortunately, many Panasonic and LG TV sets will not allow you to change to force PCM output, so you need to buy a separate decoder.  A high quality decoder is expensive, the cheap ones delay the signal.<br /><br />So, my Tvlink II works with my Samsung TV once I changed the audio format, but not my Panasonic.
