Missing center audio channel on 5.1 decode

Hi there,

In my setup I have a Vero 4K connected with the TV with HDMI for just image and connected to my audio system with SPDIF for just audio. My audio device is able to decode DTS and AC3 audio. For other formats I have to rely on Vero 4K to do the decoding. This always use to work just great with my Raspberry Pi with OSMC installed.

Anyway, now when I play a movie with let’s say FLAC 5.1 audio, which cannot be decoded by my audio system, then I hear some audio, but not all channels. It sounds like I hear only the rear channels, through the front speakers. But it could also be that I have all channels except the center channel. There is no speech, because the center channel is missing. When I switch the decoded audio to 2.0 or even 4.1 channels, then all works fine. When using passthrough then it’s also working fine.

Any suggestions on how to fix this would be highly appreciated :slight_smile:

Thanks :blush:

Similar to this?

From the movie playback interface, does toggling e.g. “stereo downmix” on and off, restore the full 5.1 channel output?

Do you have the “Player -> Videos -> Adjust display refresh rate” set to “on start/stop”, or perhaps “always”? Does the problem go away after setting it to “off”?

Thanks for your answer :slight_smile:

I’m not sure if it’s related. Actually in my case I don’t want any downmixing or upmixing, since the source is 5.1 channels and my audio system is also 5.1 channels. So I guess the Vero should just decode it and play it as is over SPDIF.

During playback, switching stereo upmix on (and off) does not bring back full 5.1 audio, unfortunately.

I have it set to off, the default setting. Changing it does not affect the issue.

Hi,

FLAC can’t be passed through, so it needs to be decoded and passed as LPCM.

Have you selected HDMI output instead of PCM (which is default) and configured your audio settings properly?

Some devices also don’t handle LPCM for multiple channels properly. So enabling AC3 transcoding will definitely resolve this for you, and you won’t hear a difference in audio quality.

Make sure Expert Settings is enabled so you can see everything

Hi Sam,

Thanks for your answer :blush:

Yes I understand. This was just an example of a stream with transcoding being used. My problem exists on every audio stream with more than two channels, that is being transcoded by Vero. So when I disable passthrough completely and change the number of channels to 5.1 then all (5.1 or 7.1) audio streams are bad, including plain DTS and AC3 streams.

Passthrough fixes this problem for DTS and AC3 streams, but not for others, which are not available for passthrough, or just not supported by my audio device.

Yes I’m using the AML-M8AUDIO, HDMI device. I’ve tried a lot of settings and combinations, but I cannot get it to work without downmixing the streams to an even number. By the way, making it 4.1 does seem to work for speech (center channel), but it still doesn’t give me surround sound.

I’m pretty sure that my audio device is not the problem, because on Raspberry Pi with the latest OSMC version and a HifiBerry Digi+ I have no problems at all, transcoding and passthrough both work without any issues.

This will likely be a configuration issue.
LPCM5.1/7.1 works fine here.

Please can you post a screenshot of expert mode audio settings and debug log?
I’d also like to see the output of cat /sys/class/amhdmitx/amhdmitx0/aud_cap

I get

Thanks for your effort so far!

Your receiver is not adverting support for 5.1 or 7.1 PCM.

PCM, 6 ch, 32/44.1/48/88.2/96/176.4/192 kHz, 16/20/24 bit
PCM, 8 ch, 32/44.1/48/88.2/96/176.4/192 kHz, 16/20/24 bit

is missing.

Do you have another TV we can quickly plug in to as a test?

cat /sys/class/amhdmitx/amhdmitx0/rawedid will give you the raw EDID and let me check that there isn’t a problem with the parsing of the EDID, and what capabilities are really being reported.

Temporary workaround for now would be to enable 5.1 AC3 transcoding as your device reports it as supported.

Yes :slight_smile: My TV is quite crap, that is way I’m using a seperate amplifier :wink:

Not at this hour of the day, but tomorrow I could plug it in a newer television at the office, without my audio device though.

cat /sys/class/amhdmitx/amhdmitx0/rawedid gives me the following output:

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

Yes that seems to work fine :smile:

I guess the difference between Vero and the HifiBerry Digi+ is that Vero is reading the HDMI properties and using them for SPDIF output as well, while HifiBerry is a seperate device. If this is the case then we should maybe tell Vero to ignore the advertised capabilities and just send whatever we tell him to send?

The EDID doesn’t validate properly, which doesn’t help.

Understood, will be interested in knowing.

Yes, that’s correct.

Late here as well, but some thoughts:

  • Try setting channels to Fixed, not Optimized.

Otherwise we can look in to allowing you to force either an EDID or specific audio settings.
