Just got my sn25p setup and I've noticed a problem with the audio. It seems that the output to the right rear speaker is messed up. In the via audio control panel I have it set to 2+2 with stereo expander like it says to do, but when I play an mp3 there is little to no output at the right rear speaker. I've swapped speakers and it still does it, so that's not a problem. I am led to believe it is a hardware problem though because if I look at the playback tab where it shows the output levels of each channel, the right rear speaker is significantly lower than the others, even though the volume is the same. I've tried both the drivers on the included disk and the latest for download on via's site. Anything I'm missing? Am I going to have to rma?
