I have a set of Logitech 5300e speakers, and my desktop recently bit the dust. I've been using them on my laptop, but my laptop is using a Realtek driver that does not offer any control over left/right/treble/sub, etc. Is there something out there that I could use to control the sub? It's a real kicker, and it's annoying to have to turn down my sattellites so much just because i can't keep the sub loud (stupid neighbors).
