I noticed that sometimes (not always) that my unidentified albums do not show the disk #. I have verified that Roon sees, I have set the preference to file media #, I have rescanned and re-analyzed the album but without luck. I’ve also done a full library rescan. I dont understand why sometimes Roon will recognize the disk # and group the tracks accordingly while other times it will completely ignore it no matter what I do.
The disk # is stored in the file tag, either FLAC or mp3.
I just tested a few other albums this morning and Roon does not even recognize the disk # in my tag. I have verified that other programs like JRiver and dbPoweramps correctly identifies the disk #. Anyone else having this issue?
Thank you for taking the time to do this test! Then it must be something wrong with my setup because Roon does not seem to reading my tags correctly then. All of my files are on a NAS that is being accessed wirelessly. I wonder if this is the cause? That doenst make sense though because all other tag values are read correctly.
When I go into the same edit mode as you, I see disk # show up as “?”.
OK i tried all sorts of things and nothing worked. In looking at files where the disc # is recognized I noticed that there is a two digit format and there is another field DISCTOTAL. I tried editing the tag DISCNUMBER from 2 to 02 but this didnt work. I added the tag DISCTOTAL but this also didnt work. Roon continues to see the correct disc # in the tag but incorrectly displays it as “?” in the track listing.
What did finally work is putting the files into CD1 and CD2 folders as recommended by @Rugby. The weird thing is my other multi disc cd files are not put into subfolders and yet they are recognized by Roon fine. @Rugby, I am curious if you did not put my file into the CD2 folder if it would work for you.
What I get is a miss identification as a Princess and a Pea CD. I then go into Identify, search for Cafe Blue Note 2012, choose the album and moved the track down to Track 1 of Disk 2 and then hit save. And I’m back with the same info I posted earlier.
