Chromecast Audio shoud resample > 96 Khz/24 bits audio to a compatible combo

[GoogleCodeExporter]

Since firmware 1.17a introducing native 96/24 playback, Chromecast Audio will 
refuse to play any FLAC or WAV  > 96/24.

In previous firmwares, it played such streams up to 192/24, although it 
internally resampled it to 48/16.

Chromecast v1 and v2 do accept to play FLAC/WAV up to 192/24 (although WAV 
playback is currently broken on Chromecast v1).

I suggest that instead of the Chromecast Audio to refuse to play audio higher 
than 96/24, it should internally resample intelligently audio to a combo lower 
or equal to 96/24. For example, 192/24 audio would be resampled to 96/24.

The use case is to allow users to play their high-res audio > 96/24 without 
requiring external resampling, so "it just works".

Also it is better for consistency, as currently Chromecast v1 and v2 can play a 
stream that the Chromecast Audio is unable to play.

Even better would be to allow the CCA to play 192/24 natively, and introduce 
MQA decoding as well.

No addtional info on the issue in itself, but this is a total failure when 
playing HDtrack- and gubemusic-files of higher resolution. As mentioned in 
report those files worked perfectly before release of HD compatibillity on all 
my Chrome casts(2xChromecast Audio & 1x New Chromecast) al though down-scaled 
to 48/16.  

Please bump priority to "High".
