type pd my machine freezes. I know it is starting because it is telling me I have no midi in or out. I can't even escape with ctrl alt del . The message I get is: Oops :0000 EIP: 0010: [<c98ffcca>] EFLAGS: 00010246 etc etc.
Its hard to say but my first guess is a faulty sound card driver. Have you sucessfully tested other apps with audio input/output? Or... try starting PD with -nodac -noadc.
later. andy
