My MB is Asus P4S533-X and I remember I installed Mandrake 9 and the ADI1980 worked fine. Now I am using Mandrake 10.0 Official downloaded from one of the mirrors. I just downloaded Mandrake 10.1 Official from the ftp server in UK. I have not upgrade but pretty sure the sound will work. The convenient front panel sound extension doesn't work however. I suggest you download the 10.1 from the internet then upgrade your system to see if the on-board sound work.
