Description Of Issue


I found dozens of my albums missing from the library in the skipped files folder. Although the reason reads “Audio Stream Format Not Supported” all of them are AIFF PCM ranging from 16/44.1 to 24/192. Are there different types of AIFF files that Roon does not support and what can I do about them?
Please find a Finder screenshot with three of the missing files. Is there a better diagnostic tool I could use?
Kind regards,

FAQ: Some of my files aren’t showing up in Roon

First step in diagnosing the root cause can be to try and play the files with another player than Roon. If they don’t play, they might be corrupt and you have to replace them. If they play, the player software often has a way to show details about the currently playing track (including format information). You should check this out and see if the file is actually in the format you expect.

Hello @BlackJack,
The files are perfectly playable in iTunes, Audirvana, Amarra, QuickTime Player etc on my Macs, iPhones etc… All players will display the file for what it is. Here’s a screenshot from iTunes:

Hi @John_Saracakis,

Would you mind sending us a link to one of these files that isn’t importing via a PM using a shared Dropbox link (or a link from any other file sharing service)? We’ll take a look at the file and see if we can understand why it’s not importing.


Hi @Dylan,
That would be great, thanks! Where can I send you the Dropbox link?
