The cable box audio was set to 5.1 dolby digital which sends audio HDMI, the digital and analogue outputs. The other option was labeled other which did not help. I should have checked the other setting through the Sony but I did not. I will when and if they are willing to get me back for the remote control they need but don't want to spring for yet. One thing I tried was using the blue tooth feature to stream some music from my phone to the system and it was simple and straight forward. Sounded good as well.
