Here's the situation:

 

I'm looking to buy a 4K TV, but my current AV receiver isn't fully 4K/HDR compliant and I can't afford a new receiver as well.

 

I have two 4K playback devices (PS4 and Xbox1).

 

Receiver has 4x HDMI inputs and 1x optical input.

 

I figure I have two options:

 

1. Plug both PS4 and Xbox  One into the TV via HDMI, then use ARC or optical cable to send audio to receiver.

 

2. Attach HDMI splitters to the outputs of the PS4 and Xbox One, then connect them to both the TV and the receiver via HDMI.

 

The problem with 1 is that I'm not sure if it will pass through higher than 2 channel audio, but it definitely won't pass through Dolby-HD or DTS-MA etc.

 

And the problem with 2 is that I'm not even sure if it will work - will the receiver still process the audio from the HDMI when it is accompanied by incompatible video?

 

Any thoughts on the two options would be appreciated, or any other ideas?

 

Thanks

 

EDIT: And will an HDMI splitter allow CEC?

I use ARC from TV (Samsung, but not 4k) to a HTIB and it definitely passes through 5.1 channel sound.  I couldn't comment on the other sound types.  Might be worth checking before you buy what specific TV models pass over ARC

I believe they all pass 5.1 from the TVs built-in tuner, but I'm not so sure about what they do when the audio is inputted via HDMI.

 

Are you using ARC to pass anything other than audio from the TV tuner?

OK, so according to this the Sony A8F I am looking at will pass through 5.1 audio from external devices.

 

I suppose I can live without Dolby-HD and DTS-MA until I can afford a new receiver.

Good question - now that I think about it, with it being a smart TV, nearly everything originates in the TV.  I'll check with a DVD some time

One caveat to the above:

 

No TV seems to be able to pass a 5.1 PCM signal through to a sound system, so sending a PCM signal to or from a TV will downgrade the signal to 2.1

Sh!te, thanks for asking the question - I’ll be in the same position soon, and I’d not even thought of this issue.

My problem is, unlike you, I’m not planning on getting a decent TV - only a Veon cheapie but still 4K, so I’m sure far more likely to have problems! I’m also not willing to upgrade my receiver (which is more basic in sound formats it supports).

Sorry for the thread cr@p, but can anyone advise my best options to ensure 4K from a PlayStation and also DD etc from the amp if it doesn’t support 4K? Could I run video directly from the PlayStation via HDMI and audio separately to the amp via coax or SPDIF? (I think this is how I’m already doing it for an Amazon Fire.) Or can I run a single audio return from the tv back back to the amp?

Thanks for any ideas.

Sony af8 is not cheap unit.

 

To be devils advocate how important is the sound.

 

Dont buy a OLED tv but high end LED and with the saved cash buy cheapest 4k amp

 

See if you can negotiate a deal where you buy the tv and the cheapest 4k amp there is.

For most people i'd agree with you, but unfortunately (and also very fortunately) I've been spoiled by my Panasonic VT50 plasma, so anything other than OLED has disappointing black levels by comparison.

 

Ended up going for the LG C8, which actually came in lower than the Sony so I can get a decent enough AV receiver (5.1, 4K HDR, etc) without going over the initial TV budget I had for the Sony TV.

@jonathan18 your options would seem to be:

 

1. HDMI from PS4 to TV, ARC passthrough from TV to receiver.

 

2. HDMI from PS4 to TV, optical passthrough from TV to receiver.

 

3. HDMI from PS4 to TV, optical direct from PS4 to receiver.

 

Not knowing the capabilities of the Veon 4K TV or your receiver in regards to what formats it can passthrough via ARC or optical, I would suggest option 3 would be your best bet.

 

Remember that any of these options will limit you to vanilla Dolby Digital 5.1, PCM 2.1, and (depending on TV and receiver) vanilla DTS 5.1.

 

I set mine up using ARC passthrough, but for some reason am only getting 2.1 from my PS4, but am correctly 5.1 DD from by Xbox One. I'll have more of a play tonight to try to get DD 5.1 from the PS4 and let you know how I get on.

 

But I've actually decided to just bite the bullet and get a new receiver as I was lucky enough to get the TV at a price that left enough in the budget for a receiver as well.

Also, you probably should be able to sell your old receiver on Trade Me to offset the cost of the new one.  That's exactly what I did when I realised my receiver wouldn't handle the new 4K standards.  I sold my 4 or 5 year old Marantz SR5008 and got $550 - from a buyer who either didn't know or didn't care about Double Vision etc.  Then got the latest SR5012 at really discounted $999 from AV World.  So upgraded the compatibility etc going forward, plus some other bells and whistles, for $450.

HD fury products can help in situations where you have a 4K complaint device and non 4K complaint device.  Or any variations in-between :)
