I recently purchased a Dell XPS 15 9550 and I love it. The speakers work well, I set defaults proper;y, etc. etc.
However, I have a 5.1 Logitech surround system. plugged into a usb soundcard (vantec 7.1) and while there is sound coming from my speakers, it is only from the front two speakers, essentially stereo sound. In the soundcard software, I can test each speaker individually, and they are all working and outputting sound when tested through its own software (each speaker will say its name and position within the 5.1 setup). When I play other audio, such as YouTube, or any other website, or audio file, it only plays from two (out of 6) speakers.
The Dell audio manager is no help, I mute the realtek speakers and microphone and it still plays from two speakers of my system. I try to change the "speaker setup" in the Dell audio manager to anything but stereo, and the drop down menu refuses to open, so there is nothing for me to really click on. I tried reinstalling the drivers to no avail.
Does anyone know of a fix?
