alsa-mixer: only use switch to mute Front in the Headphone path

According to the alsa-info.txt in the pipewire issues of 747 and 1206,
the Front Playback Volume is shared by Headphone and Lineout or
Headphone and Speaker, But Headphone, Lineout or Speaker they all have
independent Playback Switch, change to only use switch to mute the
Lineout or Speaker. This could resolve the issues of 747 and 1206.
