I recently bought a Sonos ARC, wich supports DD5.1 but i am having trouble getting the DolbyDigital 5.1 output in to the Sonos.
The sonos app, shows what kind of sound it is getting, and I am a bit lost with the plenty of options, I’ve been trying them all (passthrough on and off, setting different channels, etc.)
To test I have been using a file in a high speed USB:
the same file when i put it in my iMac Plex Server I am able to see it in the build in PLEX app in the TV (LG 47LB700V ) it outputs DD5.1 according to the SONOS app.
there are so many variables in the AUDIO configuration, and I have been reading all the info in google about it but no luck, sometimes i get no central audio, the only way to hear it properly is using 2.0 channels but that is a waste of such system as the sonos ARC
My question is, can somebody tell me which would be the ideal software setup configuration for my
OSMC Raspberry Pi 3 / Sonos ARC to exploit their capacities better ?
in the AUDIO configuration now (no dialogue unless i put 2 channels)
Audio OUTPUT: HDMI
Output configuration: Best match
MAintaing original volume: off
Stereo upmix: off
include LFE: 100
Resample quality: GPU Accelerated
Dolby Digital AC3: on
Dolbi Digital Plus E-AC3: on
DTS capable: off
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem (playing something but no central audio). You can learn more about how to submit a useful support request here.
Depending on the used skin you have to set the settings-level to standard or higher, in summary:
enable debug logging at settings->system->logging
reboot the OSMC device twice(!)
reproduce the issue
upload the log set (all configs and logs!) either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
wow, thanks so much for the speed of your response.
I managed to fix it, I will explain.
I think i found a bug or something, because the option to enable AC3 transcoding, was grayed all the time. Until I did this:
I went to the web interface and set the passtrough on from there, turning on the Dolby Digital option too, the transcoding AC3 doesnt even appear there, ever since I did that on the OSMC menu the options for passthrough dissapeared, only appearing an announcement saying “Audio Passthrough”.
There is no bug. The option is greyed out unless you have it set as 2 channels, passthrough enabled, and AC3 checked because these are the only settings in which transcoding will happen. Using another method to enable the transcoding option absent the other settings does not actually enable transcoding.
