Thanks Guenter for your quick reply (and to Miller too, for his reply on d_ugen bug)

few warnings, like "failed to open audio read port"
This is due tue the fact that SB's only support one directional sampling. Pd chooses to use the write port and therefore fails for the read port.
I should have guessed that, sorry... Does somebody have a current list of the cards that support full duplex and that have drivers for linux?

Basically MIDI is known to work ..
well, I'll test MIDI a little bit further...
You are right, I did put in some rt scheduling stuff for Linux which can only be used under root. Otherwise it will just be ignored.
I think it could be a good idea to su-id pd (not pd-gui) in the installation target: I do not think there is a security breach in this (but I am not a specialist of security). Or better, there could be a condition that allows to select whether to do this or not.
- If, for example, I call up pd, set the audio to ON, THEN open a patch like "cos~.pd" and run the oscillator, no audio happens; if I open the patch THEN turn the audio ON the audio works (this used to happen to 0.18 too)
This, or similar cases are "known" bugs. I guess they are not high priority at the moment, but anybody solving this is welcome .. :)
I'll look this up if this is still there on 0.21...
- on 0.20 when I edit the patch and audio is ON, after *any* edit operation
I can't reproduce this, but there have been two 0.20 versions, the first one had a bug. Probably we should come up with a 0.21 just for clearness. Miller ?
Well, this is extremely deterministic on my machine (it happens all the time). If this persist, I'll try harder. Does somebody know how to trap processes dying with sigsegv with gdb? (no core is produced, even with ulimit -c unlimited, and gdb says it cannot ptrace the pd process...)
