With alsa there is a ""Simple mixer control 'Independent HP'" if set to
* "Enable", sound is /only/ audible through the built-in speaker
* "Disable", sound is /only/ audible through the connected headphone/line-out
as pulseaudio only use device 0 for analog playback,
when independent HP is on , HP is only used for alt analog device 2
(auto mute of speaker by headphone is disabled)
when independent HP is off, HP is used by analog device 0
if your external speaker is always plugged into line out,
do you mean you want the internal speaker only auto muted by headphone but not
by line out ?
