I just tried two Chromecast audio for the multiroom feature.
It's easy to setup and works well!
When plugging a pair of analog headphones on each Chromecast, CCAudio1 HP1 on left ear, CCAudio2 HP2 on right ear, matching volumes I wasn't able to discern a phase difference when playing a track on Google play music: great result.
It would be worth trying after a while to see if the Chromecast audio drift and how much: if the reference clocks are the DAC ones without compensation after the initial synchronization, I suppose it will drift at some point.
One limitation I experienced is that the volume was not matched anymore between both headphones after adjusting the group volume.
But still: pretty cool stuff, I think this platform has a promising future!

Great to hear this from you. As you are really picky for good reasons! Thanks!
+Michael Panzer next it would be fun to try with more challenging setups, like when casting to a group a real-time generated stream (casting your device capture), or a local high bitrate lossless stream.
But already: there's a lot to like here ☺
One quick question I had in mind for you: Have you, and if not, COULD you try casting to a chromecast audio and a regular chromecast (even if it's the new disc shaped one), to see if it can cast audio to multiple chromecasts that are both not necessarily chromecast audio?
+Gautam Goswami according to +Sfera Dev in one of the second image in the album's comments, the groups are limited to Chromecast Audio only.
+François Simond: Hmm. It could be kinda interesting if this feature gets added in a future update. Imagine being able to stream a movie to a chromecast in your living room, and have the audio play in the kitchen or other rooms as well, as you move around the house
+Gautam Goswami Or play the same movie on two chromecast at once because you're moving between rooms! But yeah it's limited to Audio for now.
Picked one up today. Says its optical ready. Would it use a 3.5 to optic adapter? If so what would be the benefit of optic output?
+Aaron Nyquist analog or digital output? it entirely depends on what you plug it into.
If it's into an analog system, the DAC of the Chromecast is plenty capable, maybe even more so than an amplifier integrated DAC, or an additional DAC.
If it's a digital system, like one that would sample via an ADC any line-in to go through a DSP anyway you're better off using the optical out.
My system handles both. I'm just curious if there are any actual gains going optical from the Chromecast as it requires an adapter of sorts . thus not really being and optical output. Or am I wrong? Sorry for confusion . Cheers 😀
+Aaron Nyquist an adapter for the connector itself wouldn't change the fact it carries digital audio over optical
