Soundbar problems after December update

so the device will only play a maximum of 5.1? is there a reason that the device isn’t advertising 7.1? is there anywhere you’d suggest me looking in to to resolve this?

I don’t know a lot about the device, but it’s EDID suggest it only accepts 2 channel PCM. So when we try and send 7.1 channels to it, it doesn’t work properly.

With the settings suggested above, it will sound better than it did in the previous months you’ve been using it with your device.

If you have a link to the manual, it might confirm what the bar can and can’t do.

I believe this is the manual: YAMAHA YAS-107 OWNER'S MANUAL Pdf Download | ManualsLib

From p22, it looks like you should be connecting vero to the soundbar. Then vero can get the correct EDID.

Let us know if that upsets video.

Didn’t realise @liam1213 wasn’t doing this.
For OSMC to properly query those audio capabilities, it should be connected so that:

Vero 4K -> Soundbar -> TV

I have just set it up like the manual. The video seems to be fine. Shall I post the logs?

Might be useful for confirmation of audio and video capabilities, thanks.

no problem.

OK, now we have:


====================== Audio Cap =================== k3dRrf31
CodingType MaxChannels SamplingFreq SampleSize
PCM, 2 ch, 32/44.1/48/88.2/96 kHz, 16/20/24 bit
PCM, 6 ch, 32/44.1/48/88.2/96 kHz, 16/20/24 bit
AC-3, 6 ch, 32/44.1/48 kHz,  bit
DTS, 6 ch, 32/44.1/48 kHz,  bit

which means it’s advertising support for:

  • DTS
  • AC3, (not E-AC3)
  • 5.1 LPCM

I’d set channels to 5.1 + Fixed.
Disable E-AC3 passthrough
Enable AC3 transcoding.

Sam

If I put It to fixed, I can no longer edit the passthrough options, should I put it to best match and disable E-AC3 and enable AC3 or leave it at fixed?

Also, DTS Virtual: X shouldn’t effect the audio configs should it? I believe that is what takes advantage of the 7.1 according to DTS and techhive.

Sorry — it’s Best March you want

I think the 7.1 is upscaled on the soundbar (like ProLogic)

Ah I see, that makes sense. Shall I disable DTS-HD too?

To be fair, the soundbar doesn’t call itself 7.1. AFAIK DTS Virtual:X and the equivalent Dolby (?Atmos) just create the best sound field they can with the capabilities of the receiver. So passthrough is essential.

Yes. You only want normal DTS and Dolby Digital on. AC3 transcoding should also probably be enabled

@grahamh True, however PCworld.co.uk advertise it as 7.1 channels.

Thanks @sam_nazarko, thats solved the issue.

Call me picky, but they are wrong. Not that it matters if you don’t actually have 8 loudspeakers.

it seems, based off this thread, its 5.1 that uses DTS Virtual:X to upscale? so there isn’t 8 speakers I assume? they should change that haha.

Yes, they should. Retailer’s listings of specs are not always reflective of the manufacturer’s.

Sam

It depends what your TV’s HDMI out supports.
SPDIF may be a better option.
