Here is the output of that:
$ amixer -c 1 contents numid=2,iface=PCM,name='Capture Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR
numid=1,iface=PCM,name='Playback Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR
And I didn't mention that in my original post but, alsamixer has been informing me that "This soundcard does not have any controls." when I select the AudioBox via F6.
That usb audio device seems to offer no feature controls:

Alsamixer lists only controls of type MIXER, while amixer lists all - incl. those of type PCM added by alsa-lib for your soundcard.
