Found a workaround after studying many posts. Here the steps I followed:

1: I am only using front speakers for sound. No 5.1 or such speaker system 
present. Thus I am using the green jack on the side only for headphones. I used 
hda-jack-retask to override pin0x14 to be headphone only. (restart)
2: After reading up on alsa-mixer in pulseaudio I changed 
analog-output-speaker.conf in /usr/share/pulseaudio/alsa-mixer/paths in the 
following way:

[Element Hardware Master]
;switch = mute
switch = ignore
;volume = merge
volume = ignore
;override-map.1 = all
;override-map.2 = all-left,all-right

[Element Desktop Speaker]
;switch = off
switch = mute
;volume = off
volume = merge

after restart (system or with killall pulseaudio;alsa force-reload) I have 
sound because probably hardware master (pulseaudio and default) are no longer 
coupled with headphone and speaker controls.
I still have to test a little if everything works as supposed but for now I 
have sound without having to kill or suspend pulseaudio.
