mplayer won't play sound from capture device

I have an empia28xx that receives composite connections from a video source (originally used to convert VHS tapes to DVD players) and I was experimenting with it a bit. I have the device working but only the video part of it with this command

mplayer -tv driver=v4l2:device=/dev/video0:norm=NTSC:alsa=1:adevice=hw.2 tv://
But whatever I put into the alsa portions of the command, it doesn't seem to want to capture the sound from my card. I know that Linux is capable of doing this since I ran audacity with the empia28xx card and it picked up the sound crisp and clearly. Why isn't mplayer picking it up? after all of what I have been putting in the command string nothing seems to be working. Don't reccomend any other software programs for this problem because I am not interested. I plan on streaming the input of this device over a network and want to know what configurations work and which one's don't. here is the list of cards from my /proc/asound/cards

root@baron:~# cat /proc/asound/cards 
 0 [MID            ]: HDA-Intel - HDA Intel MID
                      HDA Intel MID at 0xfbbf8000 irq 47
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfbcbc000 irq 48
 2 [Em28xxAudio    ]: Em28xx-Audio - Em28xx Audio
                      Empia Em28xx Audio
