If you plugged  the speaker into the black jack,

Seem you are using stereo profile since surround dac still using channel=0

Auto mute was disabled when you select ac97 front audio panel

Do you expect pulseaudio just mute the surround playback switch but keep
the surround playack volume remain unchanged when you select stereo profile
?

Do your computer chassis have a hda front audio panel ?

> Now upon start up or pulseaudio being restarted the headphones is muted,
but the surround channel isn't any more. As mentioned I would like both
channel not to be muted.

You have to kill pulseaudio first
