Normalisation - disable by default

[CW_WFS]

Hi, 

I have around 45 users connected to my Jellyfin server {unnecessary to share this info - TDP}. The music library skips and stutters during playback when normalisation is turned on as it is by default. I've seen some posts acknowledging this as an issue.

I can disable normalisation in the playback menu after logging in and this solves the problem, but this needs to be done for every user every time the log in to a different device. 

I've 45 shared class accounts in 45 different rooms, so this keeps tripping people up.

We are using the Android app 2.6.2 on iiyama android class screens and version 10.10.3 server on MacOS.

Could anyone point me to where this default of normalisation being on is being pulled from and if there is a file I can tweak somwhere to change this default to just be "off" when users log in?

Many thanks

In the music library's settings try unchecking "Enable LUFS Scan". That is the setting that generates the normalization data. I'm not sure if unchecking that box, if it is currently checked, would remove existing normalization data.

You can also try using Finamp as the music client. It doesn't have any issues with stuttering when normalization is enabled. Though, make sure to use the beta. It has been revamped and is much better than the original version.

Thank you for replying - I have tried unticking that and creating a new library without success - but I think the problem is the default option being for normalisation to be turned on the client.

Looking at this PR - https://github.com/jellyfin/jellyfin-web/pull/6142

Normalisation is attempted unless it is explicitly set to "off" in the playback settings - regardless as to whether there's a normalisation value in the database. This causes the audio issues and toggling it off does indeed cure the issue.

I was hoping the easy way of curing this would be getting this default to be "off" rather than "track gain" but I'm a bit out of my depth trying to find what to edit. If you happen to know whereabouts to go digging I'd be grateful!

There is no way to force every client to have that disabled by default without forking the app and making the change yourself. And then you'd need to side load it on all user's devices.

IMO, the easier path is to use Finamp. It is just a better experience anyway.
