I tested this by upstream kernel 4.0.0-040000rc5-lowlatency, where there
is "Line Out" mixer in ALSA for the (second) analog output.

When I choose "Speakers (unavailable)" port in pavucontrol, Headphone
level is raised to dB gain 0 (equals 89%) and the port level controls
Master volume and Speaker volume (in ALSA). By the way, why does it read
"(unavailable)" even if it is available and playing and Auto-Mute Mode
is set to Disabled? The text changes to "Speakers", if I unplug
headphones.

When I choose "Analog Output" port, Speaker volume sets to 0%, though
Speaker unmutes, Headphone sets to dB gain 0 (equals 89%), and the port
level controls only Master volume.

When I choose "Headphones (plugged in)"  port,  Speaker volume is set to
0%, Speaker mutes, and adjusting the port level controls Master volume
and Headphone volume.

Why isn't it just so that Speakers port controls Speaker in ALSA and
does not change others, Analog Output port controls only Line Out in
ALSA and does not change others, and Headphones port controls only
Headphone in ALSA and does not change others? pavucontrol should have a
separate mixer for Master volume, and the volume control in Indicator
Plugin should control just that. Besides muting a port should only mute
a respective mixer in ALSA. It is annoying that muting Headphone in
alsamixer mutes Master and sometimes Speaker, too, (and thereafter
unmuting Headphone in alsamixer unmutes only Headphone, but Master
remains muted.) As for PCM volume, I don't know if pavucontrol should
have specific access for it.
