Question: do ALAC files play locally with iCloud Music Library?
I have nearly 8k tracks in my iTunes library and recently started using iCloud Music. Most of the music I have is ripped using ALAC from CDs. When I "get info" on the individual matched tracks in my local iTunes client, I'm surprised to see that, now that i'm using iCloud Music, many of these tracks are now 256kbs AAC audio files and listed as "AAC audio file", others are "internet audio stream" and a few are "MPEG-4 audio file" (as they should be locally).
However, when I find the local files in my iTunes Library they turn out to be the full ALAC (MPEG-4) files. My question is: Are these tracks played locally as ALAC files or as the AAC or "internet audio stream" files shown in iTunes? There appears to be no way to tell. iTunes tells me they're AAC files now and that's all I have to go on. I've spent hundreds of hours over the years ripping CDs. It would be infuriating to discover that now that I'm using iCloud Music, my music is being played over an expensive stereo system as lossy AAC files rather than lossless ALAC.
I know these untouched originals are safe in my iTunes Library, just as Apple promises. I just want to know how iTunes plays them via my home audio system from my main iTunes Library (not iCloud Music).
