Just purchased a Streaming Stick+ and I can not get 5.1 to work.
I have tried to connect the SS+ 2 different ways without any success. The first way is the stick is inserted into my Panasonic I have also tried Vudu and Amazon Prime without any 5.1 luck.[/font][/color]
If I use my TV to stream Netflix, I use the optic cable and I get 5.1 audio. Any other device (DVD, Spectrum box) that has 5.1 plays fine through my system.
You may need to go into the audio hdmi settings and tell the Roku that your TV supports DD+. Most of the channels like netflix only support multichannel audio in DD+ format. Telling the Roku that your Panasonic TV can do DD+ means the Roku will send DD+ to the TV, and hope that the TV will convert the DD+ to DD and send it out the optical port. But not all TVs will do that.
