About the DD+ test file that crashes the device in Kodi I have noticed that Kodi detects it as a 6 channels audio instead of 8 channels, so tries to set up the track as pcm 6 channels and for some reason the whole kernel doesn't like it.


Edit:

these are my conclusions for HD audio on Kodi after a whole day of tests and various hacks to Kodi's code:

- 7.1 TrueHD and Atmos -> 8ch PCM (Note: set "Off" to "Keep audio device alive" under "System -> Audio" settings)
- 5.1 TrueHD -> not ok (there are problems with 6ch PCM) but it's not a format very used
- 7.1 DD+ -> Kodi detects it as 6ch which triggers the same issue as 5.1 TrueHD (you have to telnet into the device and kill the pid of Kodi because the audio creation is pegging the cpu), I did a nasty workaround to have it detected as 8ch here, it "works" but the central channel is not playing, probably it's connected to the fact that is detected as 6ch.

- 7.1 and 5.1 DTSHD MA are played as DTSHD core, so 5.1. I tried to force enable DTSHD 7.1 passthrough here but the stream is just mute, anyway not even with Amlogic's stagefright libs you get anything more than DTSHD core.
Disabling DTS decoding from the AVR capabilities settings to try to force it to use 8ch PCM like TrueHD doesn't work, you just get no audio.

To be tested: status of passthrough on Amlogic player of TrueHD streams using a S812-H soc (mine is S812)
