Greetings,
I have the Vero 5 connected into an LG 65" G3 OLED (connected via ARC into my Marantz SR5007), and when I turn on passthrough and enable DD, DD+, DTS, DTS-HD, TrueHD etc. the sound comes out very garbled (only on shows that have said output; menu sounds are fine).
I’ve had a look through Audio hardware and software configuration and from what I can see, the reason for that is due to my Marantz AVR only supporting ARC and not eARC. Does that sound right?
If I plug the Vero 5 into an input on my AVR, then the same file I play the audio works fine with passthrough enabled.
So, if I want to keep a single remote (TV) and have the proper audio passthrough, then I need a newer AVR, right?
In the meantime, the alternative is to just plug the Vero 5 into the Media Player (HDMI) input on the amp instead and just use the Kodi remote? Am I missing anything?
If you upload a log, we should be able to see the capabilities of the remote and TV, but ideally post logs with Vero V connected directly to TV, then one with Vero V connected directly to avr.
Will be able to do so soon, do you need me to also play a video for each of the scenarios re: the audio issue as well?
No need. Just reboot then upload logs after it boots and then take note of the returned url. Hook it up the other way then do the same and then post the urls of both log sets.
Your TV will probably passthrough only DD/+ via ARC or otherwise. I don’t think most LG TV’s support any DTS passthrough and the HD formats require eARC. For maximum audio support your best bet is to plug your Vero directly into your AVR. If your only motivation for connecting it to the TV is support for controlling the Vero with the TV remote I’d think you should still be able to use CEC through your AVR. If it isn’t you might dig through your AVR’s settings to make sure CEC is enabled and if it is you might try doing a complete power reset from the wall (TV and AVR) to reset the CEC bus in case it just got a bit wonky.
OK, logs when Vero V is connected to the TV and to the AVR via HDMI (ARC).

When plugged into the AVR, CEC is still working using my TV remote to control the Vero V which is nice.
G3s have eARC.

NOTE: Most AVRs are better at passing through video than TVs are at passing through audio. I don’t know about your exact AVR but I’d imagine most people would want to plug directly into the AVR.
Yes, well aware the G3 has eARC. If you read the OP though, you’ll see the questions that I’ve actually asked. My AVR is also mentioned in the OP (and as mentioned it only supports ARC not eARC).
So it looks like my solution is to plug the Vero V direct into the AVR, but then it means that from a video perspective it can only pass through 4K @ 30Hz. That’s probably OK for now, but once I have more HDR content etc. I’ll need to upgrade the AVR.
4K above 30fps is pretty rare outside of demos and what not.
Gemini Man, Billy Lynn’s Long Halftime Walk, etc.
So you’re probably safe for a good while.
Well, I looked into the manual of the AVR and yes, missing eARC capability of the Marantz seems the root cause.
But there are cheap eARC audio splitters/extractors on the market. While playback you need to switch the AVR channel to the AVR port, the audio output port of the splitter is connected to. No idea what happens to CEC with such solutions. Example: https://feintech.eu/en/collections/hdmi-arc-splitter/products/vax01202-hdmi-earc-audio-extractor-splitter
