Hi, I recently bought an Acer Aspire 3503WLCI and the audio is a little crap. It's not very clean.. and when I turn up the volume loud it has that bzzzzing sound.
I was wondering if someone knew the best way to set your audio. In my control panel there are 2 programs called "sound effect manager" and "sound and audio devices." I also have ac3 downloaded so i can probably tweak that to.
if anyone knows how i can achieve the best audio quality from these programs or other ways, i'd appreciate your help! thanks in advance.
