I just updated my sound from an XBlive 24b to an SB X-fi card. I thought the XBlive had started to self destruct as it seems overnight my Logi5500 were no longer able to use any setting but the 6ch direct. After installing the X-fi and updating and all that blah....same thing. Only the 6ch direct works on my logi z5500s. I know the other day I was using the PLII music setting. Having not installed any drivers for the speakers and it having worked previously, anybody have any ideas why it would just stop suddenly?? I do think this card sounds better off the 6ch, but I watch movies in the movie channel and prefer music through the music channel. Any help is greatly appreciated.
