I lost sound on a Lenovo Thinkpad P15 Gen 2 with Leap 15.4 after an update a month ago. I finally found my particular solution:
hwinfo -- sound told me I had two sound cards:
Model: "Intel Tiger Lake-H HD Audio Controller"
and
Model: "nVidia Audio device"
needing kernel modules:
snd_hda_intel
and
snd_sof_pci_intel_tgl
It seems the update a month ago had dropped these kernel modules.
My guess is they were moved to a related package. I don't see how to find that out, locate failed for me. In any case, you should report in Bugzilla, that package should have been recommended and automatically installed for you.
I have now used yast2 software management to search for the kernel that provides these. It was kernel 5.14.21-150400.24.28-default I have added that kernel back to /boot/, rebooted and sound is back.
uname -a says I am using 5.14.21-150400.24.41-default
Even though /boot/ shows, dated today:
initrd-> initrd-5.14.21-150400.24.28-default
and
vmlinuz-> vmlinuz-5.14.21-150400.24.28-default
grub2 has today's date on it as well.
Carlos' solution below to remove and re-add sound did not work for me.
No, of course, if the module is gone it will not work. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
