sound card not recognized in puppy 4.00
 

Hi,
I'm an ubuntu user.
I've decide to try to install also puppy 4, a very nice OS. But sound card is not recognized.
I've tried other puppy versions: puppy 3, puppy 4, meanpuppy, wolf pup 2, micropuppy: audio is always going, except with puppy 4!!
I've seen that wolf pup is a puppy 4.00 based version! Why does wolf sound good and puppy not?
can someone help me?
thanks
