I managed to add my radio to the playlist. But if I want to edit their data (Title) I am rejected:
“1 tracks have not been updated, probably due to a write permission issue”
Audirvana Studio Radio seems to be a complete mess at the moment. Audirvana Studio does not work with AAC either, so your problem could be related, it only works with mp3, but who wants a supposedly high end player only using mp3.
I won’t subscribe to Audirvana Studio until I can get Radio AAC working on my system.
Click the station you want. Under the heart symbol which doesn’t work click the name of the station. This takes you to another screen where the heart does work. Well, it does for me.
