Try working your way through the openSUSE audio troubleshooting guide: SDB:AudioTroubleshooting - openSUSE

If that does not work, then to provide more information, with your PC connected to the internet copy and paste the following into a gnome-terminal or konsole:

wget http://home.roadrunner.com/~infofiles/tsalsa && su -c 'bash ./tsalsa' 

when prompted for a password please enter your root password. Please try to accurately answer the question on the number of plugs/jacks on your PC (for example my PC has 3 i/o plugs/jacks). When the script completes it will pass you a URL. Please post that URL here.

Also, please copy and paste the following into a gnome-terminal or konsole and post the output here.rpm -qa | grep alsa
rpm -qa | grep pulse
rpm -q libasound2
uname -a
cat /etc/modprobe.d/sound

Its quite possible you need to add a model option to your /etc/modprobe.d/sound file (ie dell-m21 or dell-m22) but I need the above information in order to make a recommendation. Once I have that information, I believe I may be able to provide helpful recommendation(s).

I’ve read of users with your model dell being successful with this edit to their /etc/modprobe.d/sound file:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=3stack 

and then restart alsa sound driver by typing su -c ‘rcalsasound restart’ and then enter root password when prompted and test one’s audio.

and I had another Dell user tell me that “5stack” instead of “3stack” worked for them.

But Dell allows multiple configurations for the same laptop, so I think it best we get the information I requested so we can ensure you get a good recommendation (and not speculation based on what someone else tried).
