Comment # 2 on bug 1188683 from Takashi Iwai

Also, in general, the Leap kernel is built in kABI compatible way, so you can
copy the old kernel module into the new kernel (in most cases).
e.g.
  # mkdir -p /lib/modules/5.3.18-lp152.84-default/updates
  # cp /lib/modules/5.3.18-lp152.81-default/kernel/dvb-core/dvb-core.ko \
       /lib/modules/5.3.18-lp152.84-default/updates
  # depmod

This will override dvb-core module on the new kernel with the older code.  Try
reboot and retest after that to verify whether the problem persists. 
Similarly, you can try to swap a module one by one and identify which module
has influence.

For removing the override, just remove the module from */updates directory,
then run depmod.
  # rm /lib/modules/5.3.18-lp152.84-default/updates/dvb-core.ko
  # depmod
