I just got this bad boy today and got ALSA set up with no problems following the Gentoo ALSA guide. This thing beats the hell out of my old SB Live, but one thing I can't seem to find any information about in these forums or via google is the I/O hub. I'm able to plug into the headphone jack, but the volume knobs don't appear to be working. I've been googling for an hour and I can't seem to find anything. So does anyone know if I can use the external hub with Linux?
