I have the Roku Ultra with optical port, so that explains it.

I have DTS off currently in the Roku settings (due to the DTS sync issue) which is forcing DTS to transcode to DD.... this is Plex doing the transcoding, not the Roku.

I have a Roku Ultra. Using latest PMS and Plex Pass client on the Roku. Are you using the same? Are your files regular DTS or or different variant?

No.  Doing that was causing Plex to convert to AAC 5.1 which the roku downmixes to stereo pcm.

No, it 100% certainly does.  I have hundreds of movies that it does this with currently.

Found a workaround I can live with!!!! Get the old Plex Classic channel: https://www.rokuguide.com/private-channels/plex-classic In the audio settings disable dts, but leave ac3 enabled Dts will now play as Dolby digital and play in sync! Not a perfect solution, as I do notice a different quality d...

Sure, that would be every single DTS Audio track in my library, which is hundreds.

While I have Plex, I rarely use it. Instead I have a DLNA server installed on my media server. I'm currently watching a movie (using the Roku Media Player) with a DTS Master Audio track, which my Roku 4 passes through to my AVR as just the lossy DTS core. If I watch really closely, I might see just...

This is worse than the old WPA2 bug you guys had in the old R2/R3 units where you had to lower your wireless security to get the software update to connect it to WPA2 because it shipped broken for whatever reason. Never had an issue up until I plugged in my Ultra. Going to be returning it. There's ...

Those of you who are experiencing this issue, are you connected through a receiver?  If so, what happens with audio sync if connected directly to the TV (bypass the receiver completely)? Yes, using a receiver.  My TV doesn't support DTS so I can't try connecting directly to TV.  Have tried two diff...

Logged a complaint with the audio sync issues a while back. I have a Roku Ultra and just updated to firmware 8.0 this morning. Audio sync issue still exist and I've tried multiple audio settings. I've seen complaints about this since January 2017. When are you going to fix this Roku? When I think a...

Still have the DTS audio sync bug with Roku OS 8.0.0 4108-29. I got a new receiver recently too, so I knows it’s definitely not a receiver issue; definitely the Roku Ultra!

Justed tested my Roku Ultra with a bunch of DTS audio movies and unfortunately all still exhibited the audio sync issue. My Roku was up-to-date at the time of this writing with v7.7.0 Build 4154-29. I’m not sure what the previous poster did or what version he has, but it definitely still does not wo...

This happens to me too... with every Roku channel.

Have you guys tried changing the HDMI and S/PDIF settings from 'Auto' to 'Dolby Digital, DTS'. That fixed it for me. Auto detect and Dolby D+, DTS both introduce lip-sync issues with my set-up. I have tried it both ways. Setting to auto results in just stereo for me. Setting to Dolby Digital, DTS r...

Can we get a response from a Roku Employee about this?
