I get this exact same problem on OS X. .. I've mentioned it before on
the list, but there really hasn't been a solution as of yet.

Any less than a "buffer 15" setting and sound is completely distorted..
I'm using the MOTU 828mk2

Still under WinXP and pd-0.36

Well, I don't understand a lot of things about it :

when I launch pd with the "-audiobuf 3" flag (so the sound card buffer
size / latency should be 128 samples / 3 ms.), I get this message :

=======================================================================

nchan 8 flags 3 buffers 0 framesperbuf 256 warning : number of buffers 0 less than recommended minimum 2 ======================================================================= ======

no latency, but the sound is completely distored (~ buffer error)

When I add the "-blocksize 128" or "-blocksize 64" flag : ~ same
results ("framesperbuf" looks to be controlled by the "-blocksize" flag)

to avoid this, I have to put at least "-audiobuf 15", and I get this
message : ======================================================================= ====== nchan 8 flags 3 buffers 4 framesperbuf 256 ======================================================================= ====== and too many latency of course

strange : when I don't use "-audiobuf", I get :

====== nchan 8 flags 3 buffers 8 framesperbuf 256 ======================================================================= ======

Is it really the ASIO Hammerfall driver I am using ? how can I be sure
?

Before I switch again to Linux, please tell me which pd command line
you use successfully under WinXP-pro

thanks a lot
