Hey Raymond, sorry for late reply. > i don't understand how do 5.1 or 7.1 work in headphone ? > do each headphone has a subwoofer ?
I took a photo of one piece of the headphones and I think there's only one speaker in there - http://i.imgur.com/OA6ZmWq.jpg As for the sound, when you enable 7.1 on hardware mode it changes the sound to create a spatial effect - it works, but some of the bandwidth is lost (you don't hear some sounds). Sadly because of that I prefer 2.0 mode. > can you try the following to find out whether the channel map is cooect I'll attach the log below (translated to English from Polish).
