If I go to options - audio - speaker configuration and select headphones, it switches back to 2 Speaker after I click apply and ok.
Is there a way to force it in headphone mode or does it only work with 2 speaker mode in Linux?
Headphone mode offers slight better htrf's for headphone 3D sound -- http://en.wikipedia.org/wiki/Head-related_transfer_function
It works in software mode so it should be hardware independent.
Thank you. =)
