OK to upgrade roku 3 to roku premiere+ for mp4 aac 5.1
Hi, if I'm a happy camper with roku 3, is there anything to watch out if upgrading to roku premiere+?
I just want to sanity check that if I have video files encoded as .mp4 and aac 5.1 audio (created by plex 'optimize for TV' setting from .mk4 dts-ma audio files) and that those files play fine on my roku 3 and are received today on my 2015 Denon avr-x2200w as Dolby Digital, then I will get the same behavior with the premier+?
In these statements here, what I am experience is the latter bolder part correct?
Stereo and 5.1 AAC (Advanced Audio Coding)
Roku devices do not support stereo AAC pass-through. Instead, Stereo AAC is transcoded to PCM stereo.
Roku devices do not support 5.1 AAC pass-through. Roku TVs and some select Roku players decode 5.1 AAC to PCM stereo. For Roku devices that support Dolby Digital Decode, the audio will be down-mixed into stereo for headphone, internal speaker, and HDMI/ S/PDIF (optical) output. **However, if the Roku player is connected via HDMI or S/PDIF (optical) to an A/V Receiver that supports Dolby Digital, the audio will be transcoded to Dolby Digital (AC3).
Also, just to validate I don't need the roku ultra with dolby decode as my AVR already is already happy with 4k, DTS, DD+ etc
