After installation of multimidia packages from Packman repositories I lost the sound. The sound was working fine before that. The first thing I tried was to uninstall or reinstall all packages changing the provider to openSUSE when possible, but it did not work. The packages are listed bellow
k3b ffmpeg lame phonon-backend-vlc phonon4qt5-backend-vlc vlc-codecs libdvdcss2 libxine2
h264enc x264 x265 gstreamer-0_10-plugins-bad gstreamer-0_10-plugins-bad-orig-addon
gstreamer-0_10-plugins-base gstreamer-0_10-plugins-ffmpeg gstreamer-0_10-plugins-good
gstreamer-0_10-plugins-good-extra gstreamer-0_10-plugins-ugly gstreamer-0_10-fluendo-mp3
gstreamer-plugins-libav
My system is:
# uname -a
Linux linux-7l6l 4.4.120-45-default #1 SMP Wed Mar 14 20:51:49 UTC 2018 (623211f) x86_64 x86_64 x86_64 GNU/Linux
Looking in yast2 sound configuration there are two sound devices: 9 Series Chipset Family HD Audio Controller as device “0” and GM204 High Definition Audio Controller, as “Not configured”, but my alsa information script says that both are installed (it may be found in http://www.alsa-project.org/db/?f=54c87a213147e1aac8b1098328dc8ef0f869964f).
Also looking in VLC menu Audio/Audio Device I see only one option for GM204 High Definition Audio Controller Digital Stereo (HDMI).
The output of lspci, amixer and aplay are shown bellow:

I have tried to install the nVidia drivers but, after many trials and tribulations I gave up and stick to the nouveau drivers for now. So I am thinking that the nVidia sound device is not working because the drivers are not installed. I just do not understand why the motherboard sound device is not working.
At this point I am tempted to reinsntall the system again…
I thank you in advance for any help anyone can offer. It will be very much appreciated!
