What does that mean, can I change the settings of my ATV3?
The ATV3 can pass the AC3 stream to its HDMI and optical ports, but cannot convert AC3 to AAC. If you have an AC3 capable TV (or an AC3 capable amplifier), they will play AC3 audio (2ch or 6ch). Otherwise you will have no sound.
To avoid this, I have developed (it’s in the last PlexConnect version in the iBaa repository) a new ATV parameter, called
Dolby Digital, whose default is
Off, that used to force PMS to transcode any AC3 stream to AAC. That is the intended behaviour. And users willing to benefit from AC3 can turn it to
But this new line in the iOS profile
<Setting name="HlsExtraMultiChannelAudioStream" value="ac3" negates what I have developed. My hopes are that the ATV3 is the same generation of the iPad4, and Plex had to solve a similar problem in the iPad4. I will interlock with the developer to know when this fix will be available, and will try to test if it will solve the ATV3 problem, otherwise I will have to think on a solution.
The fact is, who has AC3 capable players wants 6ch sound when available. And the other users want to play sound even when there are no AAC tracks in the film. So we need to have both options when using the same profile.
