HDMI issue....

HDMI issue with knoppix 6.7.1 on HP Pavilion g6-1b67ca

I want to connect to my TV (for movie watching from my Laptop) via HDMI cable
but I have no graphic /sound output from MPlayer.
I checked HERE and got this terminal output:

root@Microknoppix:/home/knoppix# aplay -l

I also attached a screenshot from
root@Microknoppix:/home/knoppix# alsamixer

I have difficulties to interpret and handle the alsamixer window.
Can somebody help me with that, please?
