Unable to get dd 5.1 sound from chromecast in any app 0 Recommended Answers 50 Replies 115 Upvotes

I have tried casting videos with 5.1 surround sound to my CC Ultra from many different apps such as Netflix, Youtube, Viaplay, HBO etc. The video casts fine but I only get stereo sound. I have 2016 Samsung uhd tv with tizen. All the smart tv's built in apps output 5.1 surround sound. Also casting from my device directly to tv I get surround sound as well as when using xbox. So the problem exists only with chromecast. Netflix app forexample doesn't even give me the choice in audio options to select anything else than stereo sound when using chromecast.

I’ve never been able to get DD 5.1 audio from any of my Chromecasts when connected directly to my television. I’ve  always assumed it’s only available when connected to an A/V receiver.

I *had* working 5.1 audio on my Chromecast 2nd Gen. using both Plex Media Server and Netflix (from Android smartphones) until the firmware update came in around Oct / Nov of 2018.

I know the HDMI destination port for my Chromecast reports 5.1 audio capability (via EDID) since my Blue-ray player uses the same destination device and produces 1080p 3D with 5.1 just fine.

My HDMI destination is an HDMI switch with TOSLINK audio extraction with ARC disabled.

Did the Oct 2018 update get more strict with the HDCP requirements?
If I knew what the technical problem was, I could likely fix it and help everyone else out with the solution.  I am a Sr. Integration Developer at one of Canada's leading integration companies.  I have direct access to the Crestron product portfolio with audio, electrical and computer engineers in my circle of co-workers.

I chatted to a CC support guy, and as per him they cant do anything (as per them all is good, if the user is able to cast and sound/video is coming out) I guess a surround sound is not a priority for google...
