Hi, i'm looking for a little help with my sound issues too, but my Windows 8.1 Performance Analyzer has a slightly diffrent list at the top (no graph button) so I got a little stuck http://social.technet.microsoft.com, I read your reason for leaving on their website and came here to get help directly from the person who knows this stuff Basically if I sit on my desktop and open up a MP3, or a H.264 encoded MP4 or teamspeak everything is fine. As soon as I run a computer game it distorts all the sound coming from the game itself, and any MP3's, MP4's or Teamspeak that I'm running at the same time. And here is the driver versions using xperf -I DPC_Interrupt.etl -a fileversion > fileversion.txt like at the end of your origional post. Just as a note there might be something wrong with the electricity coming out of the plug socket that the PC is plugged into, I'm looking to change rooms or call an electrician sometime but I'm looking to see if its a driver problem first before I go spending money on electicians or lugging my PC around the house
