Recently have been getting into 4K files, however; I have noticed that they are not being allowed to direct play from server but instead get transcoded down to 1080p due to the fact that the Roku device will not direct play files with AAC. WTH! Is there a way around this other than finding non-AAC files? Maybe it is time to be done with Roku. My model is 4630x (Roku Premiere+) and software is 10.5.0 Build 4201-29.
Re: Direct play from plex server won't work with AAC
Here's the quote from a Roku media playback support page:
Support for AAC (Advanced Audio Coding)
Roku devices do not support AAC pass-through. Instead, Stereo AAC is transcoded to PCM stereo.
Roku TVs and some Roku players decode 5.1 AAC to PCM stereo for headphone, internal speaker, and HDMI/ S/PDIF (optical) output. However, Roku devices that support Dolby Audio decode connected via HDMI or S/PDIF (optical) to an A/V receiver that also supports Dolby Audio, will convert the audio to Dolby Digital 5.1.
