Apologies if I'm not understanding your reply.

There does not appear to be a problem with probe_mask=1 , as when he uses that 
as below, the sounds work on his Medion MD96420 laptop.
options snd-hda-intel probe_mask=1

What appears to be needed is a quirk to be added for the Medion MD96420 
laptop, much as you have done for the Medion MD96630 above.

It appears that you need more info to add the quirk. I can find the vendor ID 
(17co Wistrom Corp), but no product ID's are listed.

Any suggestions as to what he can do to get the necessary info that you may 
need to apply the quirk for this machine?

Nigel.
