The track have 0 metadata, this looks like the usal Plex removing them sometimes for whatever reasons.
This file have replaygain and symfonium applies the replaygain according to the tag in the meta:
2025-11-27 21:06:07.717 Verbose/ReplayGainParser: Final gain: -9.0
Any possible solution? Or just some hiccup that is expected with using Plex through Symfonium, with no workaround?
Sounds like it from what Tolriq was saying.
I donāt use Plex myself so I cannot help you further. Iāve shown you that symonfium will read the tag if its there at least.
Yeah. And if no workaround, Iām going to have to go back to working with PlexAmp, sadly. My use case has changed from just wanting good download media sorting for playing albums, to being able to play my entire downloaded collection on shuffle with loudness levelling. PlexAmp does this. And that is, if there is absolutely no workaround. There is a lot Symfonium does better than PlexAmp that Iāll miss if I have to go back, but it would just suit my current need better.
Symfonium does this using Replaygain Tags as I have just demonstrated.
The issue is with your provider if it decides to not deliver all the metadata to the client.
Iām not blaming Symfonium for Plex bugs. Itās like how there is a bug with Plex, where I will favorite a song in an album, then sometimes it will also favorite like the live and/or greatest hits version. And I just want what I favorite to be favorited, cuz itās the best version. It happens when I favorite through Symfonium and sync it to Plex too, but I know thatās Plex having problems.
Anyway, itās already been kind of a headache getting set back up on PlexAmp. I havenāt used it in at least 2 years, thereās been 0 progression on how downloaded media is handled. They are OK leaving that aspect as-is it seems.
Yes no workaround, donāt know why Plex removes metadata sometimes but not always, and ExoPlayer still have not added the missing piece to handle a workaround there.
Then change providers and ditch the plex pass?
There is literally a handful of free alternatives that dont cause the issues you are describing. (Navidrome, Jellyfin (10.10.7), LMS)
Not my server, not my decision, not likely to happen.
EDIT: I also have at least 10,000 favorites, and many album details edited on Plex. AFAIK this stuff doesnāt just port over, and Iām not interested in started from 0 again with this.
EDIT2: Okay, well, I talked to server admin. He is going to look into Jellyfin. I guess he has been thinking about it for a while. I am wondering, with the favorites, is that stored on Symfoniumās end too, so that if you go to a different provider, this will easily transfer over?
EDIT3: This is an 8 hours later edit, I am not really bothered if nobody responds to thisā¦ but Jellyfin finished scanning music. Man is it ever garbage compared to Plex, for sorting. Labels albums according to remaster date, not original album release dateā¦ with stuff I ripped from my CD collection that is the original release date (ie. 1988 Metallica CD being organized as 2015). That alone, no, I donāt want to go through all this metadata and correct literal hundreds of albums. Then, it is sorting some artists, multiple times under Artists. There are 13 entries for Social Distortion. People often try convincing you the grass is greener, usually there are just different quirks from going to a different yard, and this yard right off the bat is more screwed up than sticking with PlexAmp.
Your tagging is garbage. Thats the issue not the server. 
This issue has been handled. If you have further questions or issues open up new. This post is going far from the initial ReplayGain Issue.
Plex has no issues with the tagging. The stuff Jellyfin sorted poorly also would have artist, album, track # tags, then ie. one artist (not well known) had all its stuff dumped (not going to call it sorted) in Jellyfin under 1 album. And then I check the tags and it specifies different albums. Yeah, blame the user, assume the user is stupid, etc. etc. Itās a matter of time. If I have to spend hours and hours editing everything, it isnāt a better service, itās a service with its own list of issues. Vast majority of my stuff is CD rips with tags applied or bought from digital music platforms so tagged appropriately. Social Distortion is all CD rips and it gets 13 artist entries, same albums under several of them (not even split up the tracks, just the exact same albums). If Plex literally just works in this regards, itās a Jellyfin problem. I might try Kodi but I also want to do other things with my life.
And this is still on the topic of ReplayGain. The whole reason Iām looking for another provider is to get ReplayGain to work.
And for the record Plex is one of the worst in regards to actually support tags, it does what it wants from outside sources and does not respect the tags, not talking about the lack of multi artists.

Server admin is done trying new things after Jellyfin flopped. PlexAmp giving me a couple problems I see a co-founder posting a āfixā for one then not responding when told itās still an issue (and been an issue since I last used it a couple years ago). So going back to using Symfonium and just playing albums. Maybe at some point like AI will let Symf do something like apply ReplayGain tags to downloaded media so it doesnāt need that info from the provider. Just getting my hopes up, not trying to put extra stress on youā¦ thanks for the help anyway.
I canāt fix plex removing the tags, and the needed patch in ExoPlayer is currently too big to maintain. They are aware itās supposed to be worked on on their side, but they stopped responding on pings on that, so well who knows.
Just as long as you are aware Iām not trying to rush you. And I am not blaming you for these problems either. Obviously I find your program better since Iām coming back from a different app that seemingly hasnāt changed at all RE: my use case (downloaded media) in the last at least 2 years, maybe even longer.
Only making a new post rather than editing, so you get the notification. Doesnāt necessarily need a reply. But, I made an account on the Plex forum, so I could ask about them looking into this issue, of at least ReplayGain metadata not always getting passed along from Plex to Symfonium. I am not really expecting much, but maybe a Plex user asking can help get the ball rolling towards a fix.
Here is what PlexAmp had to say, not sure if itās helpful:
āI think the media server strips tags by default because they are extra data and malformed ones can cause players to crash.
Clients not wanting this behavior can use stripTags=0 in the /media/parts URL.ā
If that works thatās the solution but itās not present in any API docs, do you have the link to the discussion on Plex forum ?
