Noticed that , even though using CCA connected to digital in of CXN and its display showing PCM/ 44.1 KHz, the lossless label on apple music goes away on chromecasting. This would indicate that mayb apple music app is casting in lossy format AAC and CXN is displaying wrong info. Or 44.1KHz is achieved by lossy AAC by having low bits per sample.Settling with connecting Chromecast Audio to CXN digital input for ease of use. Showing PCM/ 44.1 KHz on CXN screen, so must be CD quality which covers 90% of catalog
Ideally inbuilt Chromecast in CXN V2 should show up for streaming in apple music app. Hope CXN updates take care of that and redundant CCA device is not required
So seems like chromecasting also do not achieve CD quality due to lack of ALAC support
Another interesting experiment with Android phone is Cast my Phone option within Chromecast Audio setup in Google Home App. From there i can cast my android phone sound output to CXN directly. It plays all phone sounds including Apple music output, but the display do not show any info about cast quality.
If any android app which can cast phone sound and transcode ALAC to WAV ( like Bubble upnp), then mayb lossless CD quality can be achieved thru Chromecast with Apple Music
