PCM is what you want to see, so it looks like you will need to add a bootcode to your bootloader.
Now raise it, speakers green is unmuted which is good
Do I need to use blacklist=snd_hda_codec_hdmi
yes ...EDIT changed my mind
All of the columns that are not raised in the s/shot won't move a bit.
then quit alsamixergui then use terminal command alsamixer command
remember press the key
m = mute or unmute output volume
space bar = mute or unmute (activate) mic inputs
page up or down = raise volumes fast
up or down arrows = raise slower
and your speaker lead is using the green hole
good luck
