Bug Description

It seems that Mixxx somehow somewhere inverts phase – for playback or for recording. Exactly for which and at what stage, I don’t know.

Only master output is configured, ALSA.
Bypass EQ effect processing is enabled.
Master EQ not configured.
Recording this way.
Deck 1.

I observed the problem after loading a Mixxx recording and the original track in Reaper.

I checked further, it seems to be the deck output, and not the recorder.
I attached a picture how the original file and the deck output looks.

Interestingly only with flac format arises this problem.
At least everything is ok with mp3 and m4a and ogg.

So the bug correctly:
flac format decoded/played with inverted phase
