First make sure that you've increased the system volume up all the way (outside of Canola on the home page). Beyond that, there's a tweak you can use by setting Canola to use mplayer & then twiddling with mplayer's settings (which I've previously tried. Search the forums), but IMHO a much better solution is to get a pair of noise canceling ear/head phones. My $25 pair of jvc ear buds were THE best investment I ever made towards listening to music & videos on my tablet. HTH
