Fixed playback issues in Plex when using AAC 5.1 audio
I got excited when I saw this but after updating, I still can't find any combination of Dolby processor on/off with Plex passthrough set to off/HDMI/optical that correctly plays 5.1AAC channels besides what I was doing before by turning on DD processing and setting passthrough to optical, which limits me to 5.1 channels despite using HDMI and having 7.1.
Every other combination of settings causes only AAC 5.1 to play front left through both front left and rear left speakers for some reason. Every other format (E/AC3 or DTS/HD/MA/:X) correctly converts to AC3/DTS with the channels correct but without manually setting optical passthrough and with DD processor off it direct plays AAC5.1 to the shield and for some reason outputs stereo instead of converting to DD like it does with optical passthrough on.
