Only 2.0 Audio when using Audio Return Channel (ARC) via HDMI

Hi,

I have seen plenty about Optical only being able to pass 2.0 but it seems the same goes for HDMI audio via the Audio Return Channel (ARC) system.

I am using the following devices:

TV: Sony KDL-55W905

AV Receiver: Onkyo TX-NR626

I have my XBOX One connected to my TV via HDMI 3, I have my TV connected to my AV Receiver via HDMI 1 going from the ARC supported HDMI 1 port on the TV to the ARC supported HDMI port on the AV Receiver.

With this configuration I am only getting PCM 2.0 audio passed to my AV Receiver. However if I connect my XBOX 360 to the same HDMI 3 port on the TV replacing the XBOX One I do get full 5.1 passed to the AV Receiver. This rules out the TV or the AV Receiver
as being the root cause as the only thing changing is the audio source.

Just for clarification if I connect the XBOX One directly to my AV Receiver I do also get full 5.1, it's only when ARC is involved that it drops to 2.0.

(If anyone is wondering why I am not just using it through the receiver it's due to the XBOX One not correctly identifying itself as Full RGB colour space to the TV automatically, so I have to set the TV up for Full RGB manually and in doing so it causes
issues with other video sources, so to get around it I am leaving everything else going through the receiver on HDMI 1 and just putting the XBOX One through HDMI3 directly which can be configured independently picture wise, however this lead me to discover
the audio issue above)

Is this audio issue (and the Full RGB reporting) something that is being addressed?

Thanks

Russ

 

xbox one's tv abilities?

ARC is Audio Return Channel. It allows a TV's audio to be sent back to the attached receiver via the HDMI Out of the receiver instead of having to run a separate audio line from the TV to the receiver. It's intended for use when using a TV's internal tuner
via an attached antenna or cable source.



HDMI CEC is what allows your TV's remote to control other components without actually programming the remote with the code for the other devices.



HDMI CEC pre-dates ARC by several revisions. Unfortunately, few things take advantage of it.

 

Have you gone into settings/tv/troubleshooting and checked the box for surround sound beta. this should activate the 5.1..

 

I'm afraid that didn't help, wouldn't that only relate to the TV app though? I would expect a system wide setting to be under Display/Audio?

 

Microsoft support has confirmed that ARC is not yet fully implemented and supported but is being worked on to bring it in line with the 360.

 

Is ARC still not working? I'm trying some configurations but none worked so far...
