The output from alsa-info.sh

No sound comes from the internal speakers or the headphone jack of my laptop.
The programs producing the sound (eg. Audacity, Rhythmbox) show a varying sound
level, confirming that sound is being produced. Sound is not muted and is at
100%. There are no error messages in dmesg.

The problem is not confined to OpenSUSE. I have tried Fedora which has the same
problem. When I have searched the web for solutions, many have been suggested
but none have solved my problem. I have successfully forced the analog card to
be the first in the list by creating a /etc/modprobe.d/alsa-base.conf file:

alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-hda-intel
options snd-hda-intel id=Generic index=0
options snd-hda-intel id=HDMI index=1

This makes no difference to the sound. I have tried disabling pulseaudio,
without improvement.
