well, my crackling problems with usb disappeared after i ditched my sb live for a hercules game theater xp. however the volume of the xp is extremely low and its seems nothing can be done to boost it after talking to tech support. i have midiland s4-7100 speakers and with all the volume maxed out the volume is equivalent to my sb live at 75% max volume. the features of the xp are great, but unless i find a solution to boost the volume, i'll have to look for another sound card. with that said, what are some other good sound cards besides the gtxp or does anyone know how to solve my volume problems. thanks.
