I was working fine for about 2 weeks when I started hearing sound distortion. It presented itself as clamping, slowing and stuttering. Even in Windows Media Player the graphics slow to almost nothing while trying to play the file and then it may or may not start to speed up. There is frequent distortion of all sounds. For example,instead of playing the work dig in a song it will play di di di di di di di di dig. I lowered the output , reduced tasks to just audio, reinstalled the drivers from acer. Nothing works and even the boot sounds of XP have the poor audio. It now plays intermittently but is annoying. I have emailed newegg and acer to see if I get an RMA or some suggestions. Please weigh in if you have the same issue and definitely if you have found a fix. Thanks.
