Hey All. I'm running Vista Ultimate and I recently dicarded my dell speakers that came with my xps 400 b/c only the back ones worked and those cables were too long to use efficently (I don't need help on how to arrange my speakers, thats OK). The real problem is that my Sony MDR-E828 headphones won't work with the computer/the computer dosn't recognize them (so essentially I have no sound, other than the beeps that come out of the PC itself). Before I uninstalled the other speakers (after I had disconected them), the headphones only worked for the sound config (wher the CPU makes sound come out of the different speakers to identify them). Now, I can't get to any mixer or any thing else (sound test, ect.) b/c no speakers are installed, and when I plug the headphones in, all I get is static. I went to the Sony Tech support and there are no downloads for the headphones. I'm completely lost and soundless. Any suggestions on how to get the headphones working?
