Hi. My MSI GX630 gives a lot of problems, like during playback of any audio file, even those that are just part of a program (eg Windows Live Messenger), there's a noticeable crackling sound coming from the speakers. I also notice this crackling when external speakers or headphones are attached although it's a bit less noticeable with headphones. I was looking around on the net and found a thread where someone mentioned that heat could be a cause, or something to that effect. Also when playing some audio files with VLC media player i sometimes hear a stutter during the playback. This also happened a few times while i watched some Youtube videos. Could someone offer any assistance/explanation please. PS I have the latest Realtek drivers.
