ReplayGain doesn't work properly

App version

Production

Issue description

I scanned all my Oldies (local files) per file track gain using foobar2000 and saved the result in id3v2 tag.
In „mp3tag“ is a (id3v2)tag „REPLAYGAIN_TRACK_GAIN to be seen, for a example with a value „-4,51dB“.

When i play these files using Symfonium with the EQ/DSP Option (a) „Replay Gain“=OFF and alternatively (b) „Replay Gain“=Title (18 LUFS Replay Gain 2.0)/ alt: 23 LUFS …) no difference exists between these options for the value (using earphones).
When i play these files using „Poweramp“ i hear a significant difference between the options ReplayGain ON/OFF (for exemple the file with 4,51dB ReplayGain).
What i have to do to hear the using Symfonium ?

As most duplicates you probably do not restart the playback. Replay gain is applied at track start.

Thanks. This answer solved my problem.
