I just got an Sony OLED with Android TV and the button mapper app is so awesome.
I mapped the color buttons to open apps:
Yellow - Plex
Red - YouTube, (double click) YouTube Music
Green - Hulu
Blue - Prime Video
re-mapped the Google Play button to YouTube TV (kept Google Play as the double click)
It's awesome enough for how easy it makes life but it's a total game changer for the wife factor.
I think it was like $5 but money very well spent. Simple function, perfect execution.

Could we do the reverse of the instructions in the link to install and use android tv launcher on the Chromecast tv rather than the google home launcher?
These instructions show how to use the google home launcher from the Chromecast tv on a android tv device.

The original Xiaomi Mi Box was the only affordable certified Android TV device with Dolby TrueHD and DTS-HD Master Audio passthrough support, but it was removed in Android 9 by Xiaomi due to licencing restrictions.
It appears though that multichannel PCM support was also removed as stated by u/Tomahkin in its own post.
I was able to confirm this by connecting my Ematic Jetstream device (also with Android 9) to an AV receiver and it didn't play multichannel PCM either, instead, it was downmixed to PCM 2.0.
Looks like Google removed multichannel PCM support or this is a bug plaguing every Android TV device where Android 9 is installed (except of course the Nvidia Shield), either way, this is unacceptable. 😡😡😡😡
SmarTVs running Android TV with or without eARC don't support multichannel PCM with internal apps so they don't apply to this situation.
Does Android 10 support multichannel PCM or is it gone for good?. The Chromecast with Google TV, the Mecool KM1, KM3 and KM9 Pro are on Android 10, so I hope someone with any of those devices confirm this.
Please, share your thoughts.
