I have a problem with surround sound through the optics I do not know why but the version of 3.0.1 works normally but when I installed 3.0.2 and 3.0.3 so the movie can not make Dolby digital and DTS sound working. I have Force S / PDIF support checked in the settings and it is not the same from the latest version of the player. I have the Logitech Z-5500 and I send them Dolby sound from the movie and the control panel instead of Dolby shows only stereo and surround sound is not possible. Please correct it.
PS: I'm writing through Google translator and sorry for mistakes
my English is bad
