Dell Optiplex GX260, Windows XP Pro, SoundMax Digital Audio 220.127.116.1138
Problem: Soundmax doesn't allow adjustment for Bass & Treble. Most of the time, my Logitech 5500 surround system sounds great, but with my new ipod touch, oooooh, nasty sound...with headphones, sound is fine, but playing through speakers is awful. (All drivers updated)
Can I upgrade the audio driver, do I have to install a card in the computer? Which one? How to do it? What about the external audio adapters? Do they have bass & treble controls?
