--- Comment #5 from Janek fremenzone@poczta.onet.pl --- I just updated my wine to 27042015 snapshot (ie. today's snapshot). I've configured all sound devices detected by wine to be stereo. Sound is noticeably different now. When I look exactly forward in a level flight I can barely hear any engine sound, just a silent buzz somewhere in the background. If I rotate my head sound appears in one of the speakers except that now it gets louder gradually (the farther aside I look the louder it gets, achieving a maximum when I look 90 degrees sideways) whereas previously this was binary. If I turn my head left or right as far as possible (ie. backwards) engine sound completely disappears. Other sounds (eg. machine guns) seem to be correct.
