Hello,
sound was ok on my Fujitsu laptop AH530 with Archlinux (x86_64) until I
upgraded pulseaudio (and libpulse) to version 3.0.

After upgrading:

1) when pulseaudio starts, the alsa "Speaker" volume is set to zero and I can't
hear any sound. If i set again the alsa "Speaker" volume with 'amixer -c0 sset
"Speaker" 100%', sound comes back. 
I explicitly tried to set volume to 100% (hearing sound), restarted pulseaudio
('pulseaudio -k', then pulseaudio restarted automatically), verifying that alsa
"Speaker" volume was now set to 0.

2) every time I plug or unplug the headphones, alsa "Speaker" volume is set to
0, so, after unplugging the headphones, I can't hear any sound and I must issue
again 'amixer -c0 sset "Speaker" 100%' and (again) I explicitly verified alsa
"Speaker" volume before and after using output of "amixer -c0".

While headphones are connected, all is working as intended: speakers have
volume set to 0 and I can hear sound through the headphones.

With previous version all was ok: some other people on archlinux forum facing
same issue solved(?) downgrading to pulseaudio 2.1: I didn't do that because I
don't want to mess the bug. 

I don't know exactly which logs, documentation, etc. could be useful: I issued
(as root) 'journalctl -b /usr/bin/pulseaudio' but obtained empty output.

I attached output of "pacmd ls".

I can do some experiments if it's necessary.

Sorry for my bad English. Thanks in advance for your valuable time and
patience.
