I had someone create a computer from scratch and currently I am having trouble with the sound. I have PowerDVD hardware and software installed but when I go to play a DVD the volume is really low. I put it on loud and all the other volume controls are on high. When I play itunes the volume is louder but still not normal. My mother board is a K7 model number M825G. Any suggestions to increase the volume of the audio on my computer?
