Comment (by korli):

 My test procedure:
 Audio setup: output 192kHz 24bits.
 Test file: 44,1kHz 16bits. Media player is the client application.
 The mixer internally converts everything to float. The media player
 already converts to float.
 Added a debug output in Resampler::float_to_float().
 Resampler::float_to_float() delta:0.229687

 I think the mixer is definitely upsampling. So I'm wondering what your
 tests actually are.
