I don't know if this will help, but as long as the HDMI audio isn't working, my TV will display the Dolby symbol, followed by a capital D when pressing the OK button (It is an LG 47LH7020). Once I get it to work by restarting the TV, or switching input modes, the symbol is gone and the audio works until a restart.
I have the same exact issue!
