Thanks for the response Jeff. The LG tv had PCM and LG audio sync options. Tried both options and it did not work. Do I have to power cycle the tv/bose after changing the settings?

Interestingly enough I only solved the problem I had about 5 days ago, however I am not entirely sure what made it work as I made no changes other than plugging and unplugging the same things in the same places.
I left the unit and TV alone for a few months and then unplugged everything from power. The tv, the AV 18 and the optical audio cable were disconnected, I also disconnected the AV 18's connection from the unit that the speakers plug into and reconnected it after some time.
All I can tell you is that it is working now, the AV 18 shows AUX PCM and outputs the tv's audio properly now. I assume power cycling helped.
I made a lot of threats to throw the AV18 into the garbage but now we are cool. This is not very helpful I realize but I hope you find your solution!
Sacchrine, The optical cable is assigned to TV in the medicenter, correct? why is it showing AUX PCM?
Anyway, i'll try disconnecting everything and reconnecting.
