Hi,
So here's my problem : I have around 10000 audio files, mainly mp3 but also ogg, and they all have replay gain info. I can see it in the metadata, and it works fine with other players like foobar2000.
But with strawberry it doesn't for some reason. When I look at track info in strawberry, it either shows no replay gain data, or it is set to "unknown".
I have tried turning replay gain on and off, tried EBU R 128 and did a full collection rescan each time, it doesn't change anything.
If someone has any idea how to fix this I would be grateful. 
I'm on linux mint, by the way.
