96/24 support for Chromecast with Google TV?

[BlackJack]

Hello @test_VV01 and welcome to the forum.

Chromecast Sample Rates?

In the Chromecast world, there are basically two categories of audio support: devices that report a “supports high res audio” flag and those that don’t. The ones that support high res (Chromecast Audio) will output up to 24/96 out of their digital outputs. All other devices (ie: the Home series of speakers and all the Google Chromecast devices with HDMI output) only go up to 48kHz. In the case that you supply either category of device with audio that exceeds the maximum supported sample rate, th…

While this post and thread are old, I don’t see that Roon’s ChromeCast support has changed.
So if the Chromecast with Google TV actually supports an output sample rate of 96 kHz for audio streams and would also set the corresponding flag (self reporting the high-res support) then Roon would already honor that and allow playback audio up to 96 kHz sample rate. I was unable to find any official documentation/specification that shows the Chromecast with Google TV supporting 96 kHz over its HDMI connector though (and anything else seems to be unofficial and tinkering). But if he does, it would be best/easiest if Google would just set the high-res flag they themself specified for ChromeCast.

As this doesn’t look like something Roon support can help you with but rather a feature request instead to me, I suggest you add your vote to:

Chromecast - Override missing ‘Hi-Res Flag’ to enable 24bit/96kHz streaming

As the title suggests, it would be great if we had the option under a device’s settings in Roon to disable the ‘Hi-Res’ flag option for streaming via Chromecast if that particular device does not have the ‘Hi-Res’ flag enabled due to poor implementation by the manufacturer despite the device being able to support 24bit/96kHz streaming.

Note: I’m just another Roon user and can’t speak for Roon Labs.
