Yes, Minix goes through TV which passes 5.1 to my Sonos Playbar 5.1 kit.
I also have an EDID emulator for testing (hasn't made any difference).
As long as I know the Neo U1 will pass Dolby Digital 5.1 through HDMI I will do some further troubleshooting. Didn't want to spend a lot of time if it wasn't capable.
Hello, yep I can pass DD5.1 through from my Blu-ray player (it transcodes DTS on the fly to DD).
Didn't realise CEC had any influence on the HDMI audio pass through, will give that a try.
CEC (and/or ARC function) would only be a factor if your Sonos soundbar is also connected to the TV via HDMI too, which as I understand it isn't. So
ignore anything regarding CEC as it wouldn't apply in your case.
(My apologies that I didn't pick up on that before I commented on it earlier !!!)
Presumably your specific TV definitely supports Dolby Digital surround passthrough/output via SPDIF if it's currently working with your Blu-ray player? (Many TV's still don't support it & if the Blu-ray player is actively applying some form of on the fly transcoding before the audio signal actually reaches the TV that could also be a factor why the Blu-ray player works but other devices don't. Worth double checking the capabilities & specifics of all the devices in the chain in advance before you end up repeatedly banging your head on your desk, or take up basket weaving instead
. It certainly sounds like you've done your homework in general, however
.)
Are you absolutely certain your media sources are always DD/AC3 too? (If a streaming app, as an example, is outputting in something other than DD then obviously the audio signal may not passthrough your TV & if it does, it could in turn be an audio format the Sonos can't support/decode either
== no audio! (I.e. DTS.)
Otherwise, back up a little as it may help to clarify a few other points.....
You have also correctly configured the audio settings on the U1 itself for HDMI audio output too right
??? (Success may still depend on exactly what your specific TV can or will passthrough, however.)
Double check a few things for the U1's actual audio output settings.....
Digital sounds would ordinarily be set to
auto or HDMI. (Having said that, because your system is essentially a mix of HDMI passing through a TV via TOSLINK too I'm not entirely sure how effective this may be. I used to have a U9-H connected to my old external audio hardware by TOSLINK alone before I upgraded to a dedicated AVR, for example. I just needed to set the output device itself to SPDIF with my old equipment whereas now everything uses HDMI so it's obviously set to HDMI. (The U1 & U9-H share quite a lot in common especially when it comes to the available user settings.))
Dolby Sounds - DRC mode would ordinarily be set to
LINE with HDMI too. However, you could also try experimenting with the
RF setting as well & see if that helps.
Sound devices manager - Also set to
HDMI for the
output device.
If that still fails you may need to consider some other alternatives & I'm assuming you'd rather not shell out for a new AVR plus speakers
?? Unfortunately, the Playbar only has the one SPDIF input too so you can't just have an additional TOSLINK connection going from the U1 directly into the Sonos either.
(Although, you could purchase a basic
2 in 1 out TOSLINK splitter which could then give you a direct TOSLINK connection from the U1 (which you'd then simply set to SPDIF), & you'd still essentially retain the current connection from the TV to the Sonos as well. Or, if you wanted to avoid/bypass using the TV to passthrough audio altogether, you could even consider a
3 or 4 in 1 out TOSLINK splitter & connect each individual SPDIF capable device you own directly to the Sonos system that way. Then, just manually switch between the U1 & the TV's optical outputs on an as required basis, (or any other device depending on which splitter you choose). Audio quality wise you'd notice no different at all. It's another option you could consider for a relatively low cost if your TV just won't play ball with its own passthrough capability
.)
FYI, (I've never used it but), Kodi also has an option for DD/AC3 transcoding that's often missed that "may" help in your situation.
In
Kodi's settings -> system -> audio.... If you just leave the
number of channels set to
2.0, an additional option should then appear under the audio passthrough options to
enable DD/AC3 transcoding. (If you've set the number of audio channels to anything other than 2.0 the DD/AC3 transcoding option won't be visible.) Obviously, you could also experiment with that particular setting & see if that helps with your situation/setup too
. (Don't forget to set Kodi's settings to "expert" for these extra settings to be available to you if you haven't already.)
Hope that gives you some additional things to check and/or experiment with, or of course you could consider a simple & cheap TOSLINK splitter as explained.
Do let us know if you successfully resolve the problem one way or another. Finger's crossed
