ac3 support on new chromecast

[sahilg009]

I am currently using chromecast 2014
I was wondering if chromecast 2015 supports ac3 without transcoding

I'm using the DS video app to cast videos from my Synology nas to my chromecast. On 2014 cc I turned on the ac3 passthrough in the app's options, but with 2015 I had to disable it to get the audio playing. I don't know if this is a bug in the app, or if the new chromecast supports ac3 decoding.
If you know another way to test it just let me know and I'll try it.

Try it with es file explorer casting option
or use allcast or chromecast
they do not convert ac3 audio
If the video with AC3 audio plays that means 2015 supports it natively

I'll try to check for you with Plex.

Update: If this is anything to go by, It doesn't seem like it. Tried playing a video with AC3 audio and forcing Direct Stream, etc. Still transcodes to AAC.

It's a PLEX bug. To stream native AC3 from PLEX you need correct some parameters in this file C:\Program Files (x86)\Plex\Plex Media Server\Resources\Profiles\Chromecast.xml

<VideoProfile protocol="http" container="mkv" codec="h264" audioCodec="aac,ac3" context="streaming">
        <Setting name="VideoEncodeFlags" value="-x264opts bframes=3:cabac=1" />
    </VideoProfile>

    <VideoAudioCodec name="aac,ac3">
        <Limitations>
            <UpperBound name="audio.channels" value="6" />
        </Limitations>
    </VideoAudioCodec>

And don't forget about enable AC3 stream support in PLEX mobile app settings
