They could be the iCloud/iTunes Match tracks, using an iTunes specific protocol for retrieving the audio data. To get them to play in Audirvana, you need to download all the songs you want to play thru Audirvana into your computer library by clicking the cloud icon present showing the album is in the cloud, not the library
I had the same problem; missing about 10% of my iTunes files on my initial sync to Audirvana. I discovered that all the missing files - every single one - were all old protected m4p files, which apparently Audirvana will not accept. I purchased a file conversion program, converted them to unprotected mp3 files, then in iTunes converted them to AIFF files. After that, I imported them into Audirvana. That solved my problem, anyway. Good luck.
I haven’t converted anything at this point. From iTunes, I have Purchased m4a files that transferred to Audirvana great. It is the protected m4a files that won’t play outside of iTunes.
Yes as a Tidal subscriber, I’ll go make a playlist there with these protected songs. I’m not about to violate the artists livelihood. I hope others have the same appreciation for artists, otherwise, we’ll have gear but nothing pretty to play on it.
I think you misunderstood my point. I can create a playlist on Tidal of the songs that I’m missing from the protected environment of iTunes, how is that infringing on anyone’s copyright?
Cheers
