BUG: No DTS Audio for Android TV

brianjwdbrianjwd Posts: 33Members, Plex Pass Plex Pass
edited December 2017 in Android TV & Amazon Fire TV

I have a 2015 Sony Android TV X850C and downloaded the latest version of Plex in the App Store. I configured the player for forced Direct Play. DD 5.1 AC3 works but DTS 5.1 doesn't. If I remove the AC3 track from the mkv file, it doesn't play audio at all. I have tried Audio Passthrough with both Auto and Off configuration.

I read the release notes and I thought DTS passthrough was working in an earlier build. Am I missing something?

mkvinfo on the DTS track

| + A track
| + Track number: 2 (track ID for mkvmerge & mkvextract: 1)
| + Track UID: 2
| + Track type: audio
| + Codec ID: A_DTS
| + Default duration: 10.667ms (93.750 frames/fields per second for a video track)
| + Name: Surround 5.1
| + Audio track
| + Sampling frequency: 48000
| + Channels: 6

If you need more information, please feel free to ask. DTS Audio is something I really looked forward to.

UPDATE:
I gave up on it. It may work now that both Android TV and Plex had significant updates since I first posted this. Using an external Plex player now and it's working fine for me. For those using ARC, ARC implementations are limited to Dolby Digital at the most. For most using ARC, it's stereo.

    I also want to add that the Video App plays the file just fine with DTS Audio. So the TV supports it.

    DTS is not working in Plex under Android TV for now...

    Thank you for replying. That is odd. Because last month December 2015:

    Plex for Android v4.16.0.472

    NEW:

    • Add preference to disable using secure connections to servers.
    • Allow layout selection for home libraries (grid, list, folder).
    • Add support for MPEG2 decoding when supported by the local device.
    • Inform the user when the app activates as the result of a previous purchase being detected.
      - [Android TV] Add support for DTS/DTS-HD Passthrough.

    I am wondering if this is considered regression.

  • BenjiZombieBenjiZombie Posts: 6Members ✭✭

    Indeed, we are now at v4.17.2.488 and still no mention of a fix for this issue.

    So far, the only viable solution for me is to disable pass-through of the audio in the app. Which results in stereo sound output, whatever the original source has (AC3, DCA, AAC, etc.)

    THere is a new version of Plex App.
    Plex for Android v4.18.0.502

    Can anybody check for some improvments with DTS 5.1?!

  • brianjwdbrianjwd Posts: 33Members, Plex Pass Plex Pass

    Checked. Unfortunately, DTS is still an issue.

    PLEX customer support. What a **** joke. Do thye even have a phone number one can call?
    This is not free software. This is expensive as hell and all they do are ignoring customers.

  • brianjwdbrianjwd Posts: 33Members, Plex Pass Plex Pass

    I'm frustrated too. If you are going to blame Sony or Google, please give us a bit more detail on why you are blaming Sony or Google. Also there are ways to file bug reports to both of them. If filed already, let's see the bug report that was filed. If we can see the bug report, we can look forward to updates on the specific topic. I don't think that is too much to ask for.

    Yup, still an issue.

    Anyone tried the new update?

    Good: Seems like they are attempting to fix!!!!
    Bad: No surround sound audio works now for me.

  • drhilldrhill Posts: 239Members, Plex Pass Plex Pass

    24hz+transcoded audio still stutters.

    Plex still does not pass through directly to a TV (with DD/DTS support).

  • BenjiZombieBenjiZombie Posts: 6Members ✭✭

    Latest update fixed the audio pass-through for me on my Sony Android TV. DD + DTS finally work.

  • brianjwdbrianjwd Posts: 33Members, Plex Pass Plex Pass

    Are you transcoding, direct streaming, or direct playing?

    Direct Play didn't work for me. I'm going to go ahead and setup a system powerful enough to Transcoding.

    So you tried DTS? I set the Direct Play to auto from forced and I am only seeing DD 5.1 (yay! which is more than before). DTS is still not working.

    Do you mind sharing your configuration settings?

  • brianjwdbrianjwd Posts: 33Members, Plex Pass Plex Pass

    I just come to the conclusion that DTS is probably decoded as DD meaning passthrough isn't working. DTS Audio is playing back but the receiver is seeing it as Dolby. So either it is transcoding the audio or there is some magic going on in the background. Since disabling Direct Play gives me no Audio, I'm going to say it's transcoding. Either way, we have audio. I will close this as answered as the subject states "No DTS Audio". We are getting audio back when the source is DTS but not to the receiver.
