The rear speaker of Quadzilla/Home Studio - the addon cards of Turtle Beach Montego II is not yet supported. 1) front and rear speakers (Surround40) or 2) 2 speakers and 1 headphone or 3) 2 speakers or 4) 1 headphone http://www.3dgw.com/hardware/soundcards/msmx300/index.php3 One nifty thing about the MX300 control panel is that it recognizes automatically what you have plugged into the Line Out's (speakers or headphones) I think the alsa application need to ask the user for the speaker/headphone configuration if it want to support Surround40.
