I have installed SuSe 10 on 3 different PCs ranging from PII166 to PIII833 to Athlon850Mhz and every installation went fine except for one thing - I was not able to get any sound out of my system. The only successful installation (including sound) was on a laptop. All three PCs have different sound cards so I doubt there is a compatibility problem. Laptop is obviously using on-board sound chip. I subsequently installed Mandriva 2006 Powerpack on two of the PCs and sound works perfectly.
I am not completely new to Linux but I certainly don't fit into expert user description.
