Raspberry DVDPlayer AC3 Passthrough

Reported by: Psyduckap Owned by: fritsch
Priority: 4 - Normal
Component: Audio playback (audio/video files) Version: 14.1 "Helix" Final
Severity: Normal Keywords: DVDPlayer AC3 Passthrough

I can't get ac3 passthrough with dvdplayer. With omxplayer the same files do passthrough.
I've tried with mkvs, BD Isos, and dvds.
All work ok with omxplayer but with dvdplayer I only get noise.
Other audio tracks in the files work well with dvdplayer. If I disable passthrough, ac3 tracks play in pcm 2.0

My setup: Raspberry pi B with Openelec 5.0.3 -> HDMI -> TV -> Optical -> Amplifier
Number of channels: 2
Changed Raspberry B with Raspberry 2 and it's the same
I think with Openelec 4.x was the same, at least with dvds

tvservice -a output:
PCM supported: Max channels: 2, Max samplerate: 48Khz, Max samplesize 24 bits
AC3 supported: Max channels: 6, Max samplerate: 48Khz, Max rate 640 kb/s

Maybe it's Sony related, in this thread http://forum.kodi.tv/showthread.php?tid=218913 we can't get passthrough with 3 different Sony tvs.

In the log I play the same file with OMXPlayer and DVDPlayer. The first works without issue and the second only outputs noise.

The file is Arrow 3x01 - La calma.mkv

If you need more information, please let me know.

No, I haven't another system
I've tried with "adjust refresh rate to match video" and the result is the same, noise.
I've uploaded another log. The file played is the same as before.

Just in case it's useful.
It seems to be sony related, here http://forum.kodi.tv/showthread.php?tid=218309 there are people who can do passthrough with other brand.

I am having the same problem with my Sony. For a test I tried passing through AC3 sound to a number of tv's: 3 different Sony's, 2 different Philips, 1 UMC and 1 Prosonic.

I tested with both OMXPlayer and DVDPlayer (MMAL).


OMXPlayer: The oldest Sony and the Prosonic stayed silent (tvservice -a confirmed, that they do not support AC3). The other tv's played sound ok.

DVDPlayer: Only the 2 Philips played ok. All the others produced noise only.

Replaced the .elf and .dat files on my RPI2 running OSMC and I can confirm that the noise problem has gone. Passthrough with MMAL now works with my Sony tv.
