Serviio does not appear to handle multiple disc albums well

Serviio does not appear to handle multiple disc albums well.

Insteatd of getting:

Disc 1 Track 1
Disc 1 Track 2
Disc 1 Track 3
Disc 1 Track 4
Disc 2 Track 1
Disc 2 Track 2
Disc 2 Track 3
Disc 2 Track 4

I get

Disc 1 Track 1
Disc 2 Track 1
Disc 1 Track 2
Disc 2 Track 2
Disc 1 Track 3
Disc 2 Track 3
Disc 1 Track 4
Disc 2 Track 4

Obviously not what anyone would ever want. I am only able to test Serviio on my ASUS Transformer Prime with UpnPlay since Serviio and my Denon 4308 are not playing nice. I have not experienced this with anyother DLNA server (I have tried them all). Often the others are unable to even sort by track (they want to sort alphabetically) so there was never any consideration to whether or not they handled multi disc albums. Logitech Media Server does handle this matter appropriately but other limitation are causing me to look elsewhere.

I am able to confirm that the same sorting issue occurs with my WD LIve TV PLus.

The issue occurs with both mp3 and flac files.

Which category are you using for this view? I assume the disk number must be included in the ID3 metadata somehow and Serviio is not looking on it yet.

Either "Album Artist" or "Artist". I tested with both flac and mp3 files. Same response.

Yes, there is a disk# tag in both the flac and mp3 files.

The current display shows track 1's alphabetically, then tracks 2's and so on.

you can create a bitbucket ticket if you want this implemented. Thanks.
