HDMI to tv or AV receiver

If that's the case why do I need a receiver that supports those formats on the ARC for it to work?
The TV I've bought is an LG B8 https://www.lg.com/uk/tvs/lg-OLED55B8PLA
The sound systems I'm looking at are https://www.richersounds.com/tv-home-cinema/home-cinema-packages/pioneer-vsx933-elac-cinema-5-1.html

It looks like you're buying a receiver anyway? So why are you worried about ARC? Just plug your sources into the receiver then one HDMI to the TV, job jobbed.
 
Apparently my tv supports Atmos over ARC (lossy Atmos when from blue ray). Does that mean it supports all the lower formats?

Because most of the receivers I've been looking at only support certain formats. And from what I can tell, if the receiver doesn't support the format you won't get it? So if my game was mixed with DTS which the receiver didn't support, I would only get stereo...I think.

Both the ones you linked support DTS just fine.
 
I noticed the lack of DTS on the Onkyo according to Richer Sounds. Never rely on a resales for info. According to Onkyo themselves, this receiver supports DTS.

You’d be hard pushed and going really cheap to find a receiver that doesn’t support DTS-HD and the Dolby equivalent at the very least. Atmos is still a bit new but is now appearing at the lower end of the market.

However this all relies on the sources being plugged into the receiver. I really do think you’re tying yourself into massive knots with ARC.
 
Just plug everything into the receiver, then one cable from that to the TV. Typically AV Receivers by this point support everything you can throw at them, and indeed both the ones you linked do.

See this is what's confusing me, some sources will say it supports something when another says it doesn't. That Onkyo apparently doesn't support HDR, yet I saw a youtube video where a bloke shows HDR working with it.

To answer the question "What if the TV doesn't support the audio format?"

When you use HDMI to connect two or more devices to make a chain e.g. source > TV, or source > AV receiver > TV, or (as you are considering) source > TV > AV receiver (via ARC); then one of the things that happens is there's a to-and-fro communication between all the devices in that chain. This is called the HDMI handshake.

This handshake establishes a common set of standards. In the case of source direct to a TV, then the TV will report what sound formats it can accept, and so the source will make sure it only delivers compatible audio.

For example, lets say you are playing a BD disc with DTS Master Audio, but the TV doesn't understand that format. The BD player will down convert the audio to something compatible such as basic stereo with Pro Logic surround encoding.

The TV can deal with that, and also pass that signal to its Optical and ARC connections. The TV then is throttling the audio down to a low standard because it is sitting between the source and the AV receiver. In this way, the TV should always get some form of audio if the receiver isn't on, but it may not be good audio, just something adequate instead.

When you change the order that things are connected, then the behaviour as a result of the handshake changes too.

Connect the source to the AV receiver first, then the receiver to the TV, and the result is very different. Now the source and the receiver can talk almost any audio format. The AV receiver will pass picture only to the TV when the receiver is on. But when the receiver is in standby, then it's as if the TV and source are connected directly.

Avoiding this audio throttling between source and sound system is why those of us interested in getting the best sound prefer to connect the sources to the receiver rather than rely on optical or on ARC from the TV.

All of this communication is the reason why it seems to take an age for the TV to settle down after changing a TV input or the source signal changing resolution. This handshake and a whole bunch of other negotiations happen every time.
 
Lord help me, I'm still struggling with this.
I want my pc to be able to play 4k, HDR games/movies on my big tv, and listen to the surround sound audio through a 5.1 av system I intend to buy before I slit my wrists.
Do I have to buy an expensive receiver such as this https://www.richersounds.com/tv-home-cinema/home-cinema-packages/pioneer-vsx933-elac-cinema-5-1.html that seems to support every format I can think of. Or is there some way I can connect everything so I get all that but with a cheaper receiver?
 
The £250 Yamaha RX-V483 supports all the 5.1 audio formats including DTS, and it does all the versions of HDR including DolbyVision and Hybrid Log Gamma.

I'd be very surprised if AV receivers at a similar price from competing brands such as Denon, Pioneer and Onkyo didn't offer the same capabilities.
 
Never having heard a home surround sound setup, I'm guessing most would sound good. But what's my best bang for buck package (speakers, receiver) for £700 and under? Preferably from RS so I can get a 6 year warranty.
I'm willing to go for the pioneer just so I can stop worrying I'm going to get a system that can't do something I might want to play. But I would rather spend less if possible.
 
Value depends on your priorities.

I get the impression that you're after the excitement of surround sound and you would like a bit of security in knowing that your kit can handle pretty much anything that's thrown at it.

The Pioneer kit would be overkill for your immediate needs, and only really come in to its own if you planned to buy some extra speakers for the ceiling effects channel at some later point in time.

The Yam plus the Elac speaker kit gives you good film and gaming surround immediately, but isn't the right choice if you want to do Atmos in a few months.
 
eARC is only really part of HDMI 2.1 afaik, but LG (and others?) have put a bodge in in the mean time which I believe is the low bitrate Atmos version a bit like DD+.
The Sony help guide for my TV says this is the formats supported through it HDMI eARC
