Yes I can hear MP3's. I went to the realtek website and got the windows xp version of the hd drivers. Installed them and rebooted the computer. Went into STO and logged in and while it was loading my screen went black like my monitor shut off. Had to press the restart button on my tower. I didn't get any menu music at the character screen as well.
Run defrag. Are you sure those are the right drivers for you sound card? If you install the wrong ones that could crash your system.
