Has anybody been able to fully utilize this sound card using ALSA? I've been able to set up analog recording. But during playback apparently the ALSA mixer does not have all of the volume controls necessary. The card, as you may or may not know, has an external "break-out-box" with just about all of the internal sound card's inputs and outputs (very convenient btw). I'm able to control the left and right channels using the master volume control, but the card also has rear, center, and subwoofer channels as separate outputs. I believe I've found the volume controls for all of those except the subwoofer channel. I've tried every volume knob but the subwoofer never registers a signal. If anybody out there has this sound card and has been able to use the subwoofer channel under Linux I would appreciate some help. Thanks, Rolando.
