No Multichannel output with Music

Hi All,

I am new with the Vero 4K and I enjoy this little box.
For movies everything is fine (except: 3D FramePacked, but this will come later, I am sure)
Following the tip from Sam I open a new topic for this problem.

I have a home cinema with audiophile equipment. Again, in film mode everything is fine (Dolby Atmos, DTS:X, DTS-HD, Dolby TrueHD) - perfect.
But I am also hearing music from my NAS, encoded in FLAC or WAV format and most of the stuff in 5.1. I am always in passthrough mode…
When I play Multichannel FLACs the processor says LPCM (fine) but plays only L/R in 2.0 (Stereo).
When I play an older DTS-CD (Police e.g.) then the white noise is outputted…
With my old Himedia Q10pro Player (now sold) the buit-in native player plays fine.

Can everyone help or should I wait for the next update of OSMC?

Thanks in advance,

I think a debug log and a picture of you audio settings in expert mode is necessary to solve your problem :slight_smile:

Ok, heidi,

here are the screenshots in expert mode regarding Audio.
Unfortunately I am not experienced enough to get access on OSMC in order to find/copy the log files.
Hope this helps so far…

Cheers, Marc

Thanks, ActionA,

please one more advice: I downloaded the log after booting the device. But the file ist HUGE.
What can be deleted?

Thanks, Marc

This can be done by going to Settings -> System -> Logging -> and selecting Enable Debugging.

There was no direction to enable any “component specific logging”.

OK, maybe I am too stupid: I select Enabe Debugging and booted the Vero.
The file is more than 600.000 lines…:sweat:

You can upload the log in my osmc upload logs

Ok, Guys - got it.
Here is the log:

Please help me - I am getting crazy
thx, Marc

In that log, what audio file did you try to play?
I see you played Get Out (2017); but didn’t see another clip being played. Passthrough was used for Get Out; so it looks like that clip is working as expected.

Hi Sam, don’t know, why this (its a movie) seen yesterday is in the log after the reboot.

Hi Sam,

Shall I perform another log file?

Cheers, Marc

Can you try play this?
And upload the log?

Hi Sam,

here it is:

Thx, Marc

Hi Sam,

may it have something to do with the 192khz issue fixed in June update?
imho 192khz are not so important than correct multichannel audio (my opinion).

Best regards, Marc

Isn’t this the same issue as mentioned in a different thread before? With multichannel audio not mapped correctly when it comes to music?
There’s still no fix for this - being on the newest build, 5.1 FLAC is still passed to the AVR as a 5.1 signal, but only the front 2.0 channel carry sound information…

There’s a bit of overlap – but I’m following all threads.

I don’t like to merge threads unless things are 100% confirmed to be the same problem; as it sometimes denies an individual a chance to get their problem personally looked at.


Hi Sam,

Despite you are against merging topics, I patched the audio drivers you suggested in the other topic regarding multichannel output. It works fine now for 5.1 Flac. The mappings seems also correct. 2.0 -> 2.0, 5.1 -> 5.1 etc.

But: DTS wav files are still outputted as white noise.

Are there any new ideas? I sent you the log file a month ago.

Thx, Marc.

Hi @heimkino-hacki

Glad 5.1 FLAC now works as expected.

As the audio configuration has changed; some new log wouldn’t hurt. I’ll look in to the DTS WAV problem and hopefully it will be smooth sailing for you


Hi Sam,

here ist the log file:

Thanks for help, Marc
