Audio that should be coming from left earphone, is coming from the right one and vice versa

[Sudarshan Kakoty]

So I've flashed a new ROM named sudroid recently ported by myself, works everything is fine, BUT the audio that should be coming from left earphone, is coming from the right one and vice versa. Any idea how to reverse that? Problems should be with Android Sound Library as headphone works fine with PC and previous stock ROM.
