USB thumb drive audio issue on Raspberry Pi 3?

Hello, seem to have an issue with no sound being passed through my Raspberry Pi 3 when playing movie files. I have the OSMC July 2016 update installed ok and have no playback issues with my Sony TV and Sony soundbar.

But I have some movies on a USB stick which I have inserted into the USB bank on the PI and I can access them via the Kodi/OSMC File Explorer.

But when I play them, no sound is being heard at all.

As far I can can see, I have all the passthrough settings correct on the Sony Soundbar (connected via the ARC HDMI port) and on Kodi so I can’t see any obvious mistake?

Do they play on any other device with audio?

Yes plugged the drive into my Macbook, no audio issues

Do you hear audio when passthrough is disabled?
What is the audio format of the files that are silent?

Note: many TV’s won’t pass passthrough formats through toslink or ARC.
AC3 is sometimes supported. DTS is much more rarely supported. See:

The files I am trying to play are MKV files (Matroska Video File) so should I convert them to mpeg or something more acceptable to Kodi/OSMC?

I have no audio when I turn the passthought on or off so maybe a file issue I guess

Provide mediainfo of the file and we can confirm one way or the other.

Ok how do I that please (I’m on a Macbook here)

The file looks fine.

Exactly how are all these devices connected to eachother?

I’ll check but its via the ARC HDMI port on the soundbar and the PI is connect directly into the back of the TV.

Btw, when I change the sound to the TV output I still get no audio

I’m not sure that an ARC port should exist on the soundbar. ARC should be on the TV.

Ok… there is a port called TV (ARC) on the soundbar and I have it connected to the ARC port on the Sony TV… the Raspberry Pi is connected to a HDMI port on the TV.

So did you check ARC settings on the TV itself?

Yes I did, playing movies and there’s no issues with sound…

So the issue is resolved?

Excuse me, misphrased that. Meant to say, I can stream movies and they play with sound no issues.

Then provide logs of a file failing to play correctly.

Here is the log location of my playing for the file, hope this is correct
