Convolver + ReplayGain

[simoncn]

You need to use the setting flac:wav24; instead of flac:wav24. The semicolon tells MinimStreamer to use FFmpeg for transcoding instead of its own internal converter. The semicolon is only needed for FLAC, so your complete setting should be

stream.transcode
mp3:wav24, flac:wav24;

With these settings, positive replay gain for FLAC files is working for me. However, I cannot get positive replay gain to work for MP3 files, only negative gain.

This seems to be a problem with FFmpeg rather than MinimStreamer. I ran FFmpeg directly from the command line on some test files and the result was the same.
