That’s not entirely true. When I play albums from multidisc (Beatles “White Album”, Derek & the Dominos “Layla…” etc.) the player crossfades instead of genuine gapless. 
Plexamp 1.1.0
Plex iOS 5.13
Plex Media Server 1.15.5.994
Plexamp is not the regular iOS Plex app.
Sorry! But in iOS happens the same. Crossfading instead of real gapless with multidisc albums. In Plexamp on Mac the same happens. So I suppose it’s a server problem?
How do you start playback of these albums and are they really added as a multi-disc album or did you create a playlist to combine the separate album entries for disc 1 and 2 together?
For me it works with true gapless on desktop for real albums (but not in the regular mobile Plex app, which does things differently).
I play them in real album mode. I select an album and hit the play-button. No playlist involved. Regular albums work fine.
My music is organized as: Album artist/Album title/Disc no./Track no. Track title.
This is the file organization.
What about embedded meta tags? The ‘Album Title’ meta tag must have identical content for every track – even in multi-disc albums.
Which means that it must not have the disc number or disc title in there.
Otherwise Plex will consider disc 1 and disc 2 as separate albums.
Yup. The ‘Album Title’ tag has identical content for every track in the album. Thus it shows as expected the right way in Plex Web and in the apps…
Weird. I cannot repro with double albums here on Plexamp Desktop.
(Pink Floyd’s The Wall is usually the litmus test for gapless.)
I will test with The Wall myself. (Will add it to the library and report.) Thanks for now!
Oh, wait. I just noticed now that you don’t have a Plex Pass. Normally, you should never see overlapping tracks because this is a Plex Pass feature.
Well, I have a monthly subscription. As my account page shows.
And did you restart your Plex server after you subscribed? Because otherwise it doesn’t know about your subscription and might not unlock the Plex Pass features.
Your subscription is cancelled, btw.
Well, my account page says I will next be billed on May 13th… I didn’t cancel… 
Also I restarted the server several times since I subscribed.
Regular albums play as expected (gapless / no overlap or crossfade), playlists play as expected (crossfade). I like that very much BTW.
Does the Plex media info show loudness values for the tracks of this album?
Yup. It does.
Then I’m afraid we need to look at logs.
The file is named server.log and unfortunately I don’t know exactly where to find it on a Mac.
Mmm… Don’t know either. Maybe this helps? This I downloaded from the menu in Plex Web. Plex Media Server Logs_2019-05-01_10-42-09.zip (3.2 MB)
Sorry, no. This is the server log. In this case it has no information about whether Plexamp is using crossfading or gapless.
Okay. Will search then. Thanks!
Think I found it. It’s in /Users/[User]/Library/Logs/Plexamp Plexamp logs.zip (720.5 KB)
