I've tried opening it in C:Program files. I also tried pinning it to task bar and then trying to open but that didn't work either. I uninstalled the Realtek driver through device manager and then reinstalled the drivers on HP. I also downloaded Realtek HD audio manager from Realtek's site but still no luck. When i search for realtek hd audio manager on my laptop the only result is DTS audio control. When i click on sound and then microphone properties the realtek enhancements tab is blank. The only thing you see is "disable all enhancements".
