[SOLVED] Sound not working (anymore)

I rarely plug-in any sound device to my workstation. Last time was probably ~6 months ago. I do remember that it worked fine last time. But today I can't get any sound output.

I'm using the MATE desktop with Pulseaudio. I checked in alsamixer and the channel is not muted. Command-line speaker-test does not detect any issues (but can't hear anything). I tested my headphones with my mobile phone and they work find. Tried connecting both at the front of the computer (as I usually do) and in the back. Tried the MATE applet to do a speaker test, not hearing anything. Tried opening pavucontrol and in "Output Devices" Port has two options: Headphones (unplugged) and Line Out (unplugged). They remain marked "unplugged" no matter what I do.

Some hardware info output:

Hi

I'm worried that in your aplay -l the first two sound devices are the HDMI output. Pulseaudio may be trying to route the audio to your monitor.
I use gnome, so maybe the sound configuration window is not the same, but I had the same problem a couple of days ago, and it was solved by selecting HDA Intel PCH device to be the first one.

Thanks.
The analog device is selected both in the Sound Preferences of MATE and shows up as default in pacmd, so it must be another issue.

~> pacmd list-sinks | grep -e 'name:' -e 'index'
    index: 0
	name: <alsa_output.pci-0000_00_03.0.hdmi-stereo>
  * index: 1
	name: <alsa_output.pci-0000_00_1b.0.analog-stereo>

Yep. Commenting out

 load-module module-switch-on-port-available 

from

 /etc/pulse/default.pa

sorted it out. Thank you!
