Exactly, @Martin_Webster. I have the LG C1 set up for AirPlay…it doesn’t show up in the Roon snip above. My Sony A80J TV (The Bravia Device) shows in Roon, via Chromecast and that was automatic; I don’t think I did anything.
I have a 2019 LG C-series TV and have the same issue, it’s compatible only with AirPlay 2 and does not appear as a Zone option in Roon. LG does not support AirPlay 1.
An AirPlay2 sender is compatible with Airplay[1], i.e., it can send to an older Airplay device or a device that has Airplay[1] support in its firmware. However, only Apple devices are Airplay2 senders. Roon can only send to AirPlay, and these TVs are AirPlay2 receivers.
Are you sure about that? Yes, Roon supports Sonos, but it doesn’t use AirPlay2 to achieve this. As I mentioned before, only Apple devices can send over AirPlay2.
Here’s what my path looks, like (I think this is what you are asking @Bert for @Martin_Webster). Not sure how to distinguish between AP1 and AP2?
I do know when I use “Sonos Streaming” I get a higher quality, purple diamond-ie icon at the Sonos Arc endpoint, distinct from the green circular icon you see with AP.
Roon uses a reverse-engineered solution for Airplay[1], which will resample the source, and is why you see the green, high-quality, badge. In contrast, native Roon Sonos support directly sends a bit-perfect signal to the Sonos endpoint.
Airplay2 streaming is only available on Apple devices, so I would guess that Sonos has to support both AirPlay[1] and Airplay2 on their devices, which is why @Bert is using an Airplay2 device with Roon. But I suspect the signal path will only show high-quality, as with Airplay[1].
Not sure you should get green with Sonos and Airplay if it’s 44.1/16 it would pass through lossless any other rates would be resample but Roon would show it in the signal path. Sonos streaming supports up to 44.1/24 without Roon having to resample. Does Roon just assume airplay as not lossless?
If it doesn’t support legacy Airplay no it won’t as no devices other than iOS or Apple hardware support sending material via Airplay 2. Roon is cross platform and thus does not support Airplay 2 as it uses its own code to send via legacy Airplay and not the operating system.
Airplay Streaming plays green-dot-icon, which I believe is lower quality.
I cannot hear a difference. In the rRemote app on my iPhone, Airplay Streaming puts track and artist info in the Sonos S2 app, while Sonos Streaming just provides computer code-names (go figure on that, lol).
