After Updating sound stop working

Hi internet

Have been watching movies and videos all day, after I update my system `sudo pacman -Syu` there is not sound, the system doesn't see any of my output audio (I have HDMI, internal speakers and headphone connected), I check journalctl -xb and I found this:

gnome-session[674]: (gst-plugin-scanner:1096): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-1.0/libgstopencv.so': libopencv_calib3d.so.2.4: cannot open shared object file: No such file or directory
gnome-session[674]: (gst-plugin-scanner:1096): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-1.0/libgstopenal.so': libopenal.so.1: cannot open shared object file: No such file or directory
gnome-session[674]: (gst-plugin-scanner:1096): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-1.0/libgstopenexr.so': libIlmImf-2_2.so.2_2.so.22: cannot open shared object file: No such file or directory

I went to /usr/lib/gstreamer-1.0/ and all those file exists there, is this the root of my problem? how can fix this problem? (even if it is not part of my problem)

thanks in advance!

have a good day/afternoon/evening

Re: After Updating sound stop working

I can't offer a conclusive answer.  However, I'd try:

$ amixer set Master 90% unmute
$ amixer set PCM 90% unmute

Then, fool around with 'alsamixer'.  Be aware of the 'm'/MM (mute) keystroke/option (man alsamixer)

Simultaneously, read     http://tuxradar.com/content/how-it-work … -explained

Then, if it still fails, I'd dig a bit deeper:

$ lsmod | grep snd
$ ls -l /dev/snd   # https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture

and maybe read http://wiki.archlinux.org/index.php/Sound_system

Just off the top of my head.
