I currently have an onboard sis 7012 soundcard with the AC '97 codec . When I put in my Plantronics Audio .90 Stereo Headset with its own volume control<i>(has gotten good user reviews on various buysites like CircuitCity, Amazon)</i>, the volume is too low on both the mic and headphones. It's the same with other headphones too. Even when I'm just using speakers, if I turn the volume knob past 50%, it gets all distorted as if it's struggling to play the audio loudly.
So, what I'm asking is, will getting an SB Live 5.1 improve the audio volume as well as quality?
