Thanks! Gertjan Lettink a.k.a. Knurpht, installing sof-firmware did the trick, although it didn't go completely smoothly. After installing sof-firmware I tried to start the sound system using YaST2. That crashed my system, locking it up and forcing a hard reboot. But after reboot all seems to be working now and my laptop is happily playing some enjoyable tunes at the moment!

Much appreciate your assistance ol mighty guru! ;-) Marc

Hi, My new Dell XPS 15 9530 laptop is unhappy because it's sound system
is not working under OpenSuSE 15.5 x64 with the KDE/Plasma desktop. When
I tried to "configure" the sound system I got the following error message -

The kernel module snd-sof-pci-intel-tgl for sound support
could not be loaded. This can be caused by incorrect
module parameters, including invalid IO or IRQ parameters.


The YaST2 hardware info tells me the following about my sound system -

Is there a sound guru around who can help me make my poor laptop make
noise when I want to watch/run my favorite
YouTube/Netflix/Zoom/Clementine apps?  Thanks as always, in advance, for
your time and patience with me...

You might need sof-firmware to be installed.
