I’m evaluating Roon and after importing my lossless m4a ALAC library the great majority of tracks has been marked as “corrupt” and when playing, several seconds are removed from the end of such tracks. Neither iTunes nor Audirvana exhibit this problem and the files play just fine there.
I can provide sample tracks demonstrating the problem.
Actually the files were first ripped as FLAC but then converted to ALAC as it has better support on Apple devices (unfortunately I don’t remember what software I used for the conversion any more). Re-encoding the files with XLD really helps but it would be good if this was fixed as others may run into this issue too.
Below is a sample of a file with the problem. Please let me know if you need more samples.
Hi @Jiri_Techet ---- Thank you for the followup! Confirming that I have received the content and it is currently in my queue for testing. Once I have some feedback, I will be sure to follow up with you accordingly.
Hi @Jiri_Techet ---- Thank you for your patience here. I can confirm that I am seeing the same behavior on my end and a ticket has been taken out for our developers to investigate further as to what may be causing this behavior.
We appreciated your patience while we look into this issue.
Yours could be the same issue that I had. My library is mostly CD rips in Alac and I had a number of albums that were lacking one or more tracks. @Mike & co. were able to replicate some of the issues and found issues with the Alac decoder at the time. Later builds were better, but not entirely succesful. Some tracks remained missing and I also stumbled onto entire albums missing.
I my case the problem ended up being with the tag extraction. Whether the root cause was the ripping done by iTunes, Max or XLD, I do not know. Anyway, I found issues with 643 tracks out of 15823. From these two were obviously corrupt rips (small file size), two were unsupported files (DSD512) and the rest were skipped due to “failed_to_extract_tags”.
I you go to Settings > Library > Skipped Files, what does it show you? Here’s an example from mine:
