All of them ac3, bitrate differs. It looks like 384kbps and lower bitrate ac3 is not playing

Just found a movie with 384kbps played fine, and another 384kbps no audio, and a 448kbps no audio. So there is no logic.

Also, compare the frequencies. i.e. 384 at 48khz and/or 384 at 44.1khz etc.

Well, I don't get sound on the AC3 track, when using the store app. So I can reproduce this. No audio is sent to my receiver.

Ok this is bizarre. As is, the AC3 audio won't play. If I remux it and remove the DTS audio, it plays, but it does have a bit of a jerky start. But if remux it and put the AC3 audio as the second track and DTS first (switch them), then it plays perfectly.

It's good to hear somebody else can reproduce the problem. We are awaiting for resolution for a while. Just fyi, the issue can be reproduced by Emby store application on Windows 10 also. Desktop application can play AC3 track at the same movie, therefore the issue not binding to Xbox, but to store application.

That file does a lot of things (server 4.1.0.23).

In Store app:
- with no subtitles selected DD5.1, sound plays for a split second only (direct play).
- with default subtitle selected DD5.1, sound plays (direct stream)

In Xbox app (HDMI bitstream off Xbox One S sound settings):
- with no subtitles selected DD5.1, sound plays (transcoding).
- with default subtitle selected DD5.1, sound plays (transcoding)

But there seems to be a problem now with the Xbox Emby app, because it doesn't register the auto settings for Video settings>Home network quality.
It always transcodes now on my system, even when lowering Home network quality settings to 20Mbps.

What does the file do for Xbox users with sound problems ?
Is it transcoding, direct streaming or does it direct play.

Finally figured out:
-When there are 2 audio tracks ac3& dts, then only dts plays.
-When there are 2 same type tracks, for e.g ac3&ac3 or dts & dts, plays fine both
-After remuxing ac3&dts type mkv with only ac3, then plays fine.

Unluckily in my country, 90% of the movies have this mixed audio track type.
Is it possible to fix it?

I was testing your sample in Windows Media Player, and it always played the DTS track with no option to switch to the AC3. So I decided to look at the headers in mkvtoolnix. The option for default track wasn't set. So I added the element and selected, yes. Now it plays the AC3, and when I play it in the emby app, it plays the AC3 audio. So there would seem to be an issue with that.

Thank you for testing. Is there any applicable script to solve this, automatically?

Hi,

 

I'm having this problem too on xbox one ET..

 

modifying the "default track flag" in header editor doesn't resolve the problem for me..

 

I tried to re-multiplex the file mantaining the 2 tracks and doesn't resolve..

Removing the secondary english track, the italian track plays fine..

 

As the other user report, switching to the other ENGLISH DTS track (from ITALIAN AC3 5.1) the audio plays..

 

here's the direct play stats:
