I have more than 3000 flac songs about 1 TB in my Google Drive, and it says me have NO FLAC SONGS? I can use other app to play flac songs, it can also do so, but not in gdrive?
Are you sure that you are signed in to your Google account from the Music app? And did you grant the app any required permissions to access your Drive contents?
Sure, I've gave all the permissions it needs. And how can I load the songs in google drive without log in?
It shows mp3 files but NO FLAC files.
You need to log in into your Google drive account within the Sony music app and grand permissions. Many other apps use the system integrated Google drive access so you don't need to do anything else. Sony uses a separate way and so you have to Log in seperately
I've log in gdrive in music app, and found many mp3 music in that app. BUT NO FLAC MUSIC.
Did you try copying some of the flac files from gdrive to your device and then play them? If you also can't play the files from locale storage, there could be a drm problem. The music app blocks drm secured files.
Yes, I've done this, my flac is playable.
