[PD] hammerfall on osx

[Alex from Idoia]

Hi list,

I know this is the second time I send this email, but I cannot solve my 
problem and this is now driving me crazy.
So if that time nobody has a solution I will give up.

I have a Mac G4 867Mhz, it has no built-in audio input. A Hammerfall 
DSP has been installed properly.
Now when pd starts, the terminal gives the error -99999, and there is 
no audio in pd at all.
I think their is a conflict with the DSP of the card which take care of 
the audio latency, but the interface to deal with the buffers of the 
card has disappear with OSX(unless I don' t know where to find it).
I know that the error -99999 is an audio problem, I have tried to start 
pd with r -48000 and even r -22050, but it is still the same.
I have also tried different audiobuffer but I am not very confident 
with the value to use.
If anyone has any other  idea to solve that problem, it will be very 
much appreciated.

Thanks again.
Alex
