Yes, when the Chromecast gapless option is enabled, the Hi-Fi Cast app decodes & gaplessly (silently/internally) plays the audio files and the resulting LPCM audio output is what the app instructs the the Chromecast to stream.

Interestingly, the Hi-Fi Cast app can also be used to control standard UPnP/DLNA supporting streamers, but unfortunately it does not currently provide a similar mechanism for those standard UPnP/DLNA streamers that don't support gapless.
There is a UPnP/DLNA gapless option, but that's only to be used with standard UPnP/DLNA streamers that do support 'true' gapless playback, ie, when instructed to stream the individual audio files in the playlist themselves, one after the other.

When using HiFiCast for the controller it is also the player right? That is how the gapless is achieved?
As opposed to HiFiCast instructing the Chromecast to play stream after stream.

HiFi Cast is the controller, but I read the way gapless works is the server streams to HiFi Cast, which then re-streams to the Chromecast

No, in the Hi-Fi Cast's Chromecast Gapless function, the original audio files from the server are not just re-streamed, ie, implying that they are unchanged. The server's audio files are actually decoded and played (gaplessly) by the the Hi-Fi Cast app. The resulting Hi-Fi Cast app's audio output is what's streamed by the Chromecast.

This is correct. The CCA doesn't have built in gapless capability, so the app must 'tie the tracks together' and constantly stream them to the CCA directly. I don't think Hifi-Cast changes the actual audio data, I believe it still feeds what is essentially the original MP3/FLAC data as is. Probably not that simple as described though.

Well, if you think about it, the Hi-Fi Cast app's 'Chromecast gapless mode player' output is just bog standard LPCM, so no reason why it can't be a bit perfect decoding of the server's MP3/FLAC files. So the process can actually be quite "simple", as the Chromecast devices support streaming LPCM, either raw or as a WAV file.

I was thinking it would be sent to the CCA in MP3 or FLAC format, letting the CCA do the transcoding while HFCast simply weaves those files into one stream.

The easiest way to bit pefectly & gaplessly 'stitch' the files together would be to decode & gaplessly play them. You could argue that it may then be worth compressing the resulting LPCM audio stream using a lossless format, such as FLAC (but of course not MP3).

After a little googling, it seems you may be correct. While MP3 files can be stitched, it is more challenging for FLAC (which I assumed incorrectly would be easy). Apparently, as you said, HiFi-Cast decodes everyting then streams for gapless. Thanks for keeping me straight on that.

Always a good idea to google for confirmation - even throws up very similar stuff that I'd forgotten we'd both discussed before (in this very same thread)!
*Official* Google Chromecast AUDIO owners thread - post #528

Like I mentioned in that post, you can get a feel for how the Hi-Fi Cast app's Chromecast gapless support correction process works, by using foobar2000 with the foo_out_upnp plugin (and the BubbleUPnP Server to provide a DLNA renderer for the Chromecast).

The Chromecast Audio devices are now Roon capable.

I've been playing around with it the last couple days, and I've been getting excellent results.

The thing I like the best is how I can seamlessly play my high resolution collection and Tidal (including MQA core decoding) and set it up so that everything is maxed out at 96/24 to take advantage of the resolution of the CCA.

Here it's showing software decoded MQA from Tidal at 96/24:



And here is a DSD64 file from my collection being re-clocked to 96/24 taking advantage of the full resolution capabilities of the CCA:



Also, gapless!!

Isn't it the other way around? So it's Roon that supports Google Cast (and not Chromecast devices supporting Roon's proprietary RAAT protocol). That would explain why you won't be able to use Roon casting to Chromecast in perfect sync with Roon playing at the same time to its (RAAT supporting) Roon Endpoints.

I started having some random little "cuts" in the sound (very brief gaps, sometimes with a slight clicking noise) when streaming Hi Res FLACS to CCA from my Mac (usign BubbleUpnp, MinimServer and Linn Kazoo). Now, these cuts seem to become very rare and almost dissapear if I set BubbleUpnp to downsample all files to 88kHz or 28kHz with FFmpeg -which is a step below the 96kHz supported by CCA. My blind guess is that my wireless router somehow isn't strong enough to stream 96kHz files. How that this sound to you? And, if this is the case, which router would you recommend for a solid DLNA streaming?

Any CCA owners on here also Plex Users AND Tidal subscribers? The new Plex integration with Tidal has me wondering if Plex's support for native Chromecasting (and therefore Whole Home Audio) now gives Tidal (by way of Plex) support for whole-home-audio...

Can you expand upon this at all (and maybe follow-up with your thoughts/uses, if you have any)? If you're using Roon on your desktop/laptop, can you know find an integrated "cast" option that will allow you to throw it to any CCA/whole home grouping? That'd be ideal...

The good news is that CCAs are available at a big price drop (to $15) almost everywhere at the moment.

CNET article: https://www.cnet.com/news/get-a-google-chromecast-audio-for-15/

I've confirmed current (12/4) pricing at Google, Staples and Best Buy, the latter with free shipping at no minimum.

The bad news is that the consensus is that this is likely a sell-off in advance of a phaseout of the product; the AV Chromecast had a recent update and seems to be alive and well, but no such love for the CCA.

On the other hand these seem to be rock solid and don't require a lot of ongoing third-party support to be useful.

I'm getting a couple of spares while the getting is good.

EDIT: I note that AVS seems to do some tricky redirecting of the Best Buy link (to eBay in my case). You can get the actual BB link in the CNet article or just do a search on the BB page.

Yes, I can use my desktop, my laptop and/or my phone to control what plays through any of my zones through Roon. I can play through my desktop system (Cambridge DACMagic + & Dynaudio Active Monitors) or through any of the individual Chromecast devices, or through any of the Chromecast Audio grouped zones.

It's also possible to play different content of different systems simultaneously. It's fantastic, I love using Roon!

I have not been on here in awhile. I thought the Chromecast audio would be great for a poor mans Sonos. This seemed to annoying to achieve. I wish there was an easy way to output audio to multiple bluetooth devices at the same time but seems to require software or expensive device and seems to be a hassle. I'm not really seeing the advantage of owning these.


My issue with regular Chromecast was that you had to use another device to cast. Where as Roku, Amazon, Apple TV, NVIDIA etc did not. But most still has mirroring functionality. The main issue with this is bandwidth, say you were streaming down from Netflix using your router, you would then have to stream to your chromecast using wifi bandwitdth two ways. I always thought this caused a lag because 2 streams of data are required

Two key advantages (for me) to why we use our CCA's as much as we do instead of our Shields to listen to music:
1) You don't have to have the TV on to play (or control) the CCA... while also possible (play, not control) with Shield as long as you don't have HDMI-CEC on or using ARC, you still can't control it without the TV on. We like just turning the AVR on without leaving the screen running on the TV(s) unnecessarily.

2) Whole home audio. You can group up and cast to multiple CCAs (and Google Homes) all at once, and they'll play in-sync.


Whole home audio is the whole reason why I bought one, and I've liked/used them so much I'm already up to four and thinking about picking up a 5th or 6th at this discounted price...

It sounds great. I'm definitely interested/intrigued. The only problem I have is the same problem everyone has: $500 seems like a pretty steep price to pay for a piece of software that does what this does (plays back local hi-rez music files), even if it does it REALLY well...

While my wife would certainly tell you that I have all the audio gear I *need*... I don't quite have all the *end game* gear I want (Ascent Sierra Towers with RAAL tweeter upgrade, for example). It's not an easy call to allocate a full $500 toward software.

Any chance you happen to know/can confirm if you can also cast to any Google Cast supporting Android TV device (specifically NVidia Shield but the answer should be generic to all-or-none, I'd think)...

So it works well for whole home audio? Do you cast from your phone for that?
