I see no such issues here, with either 44.1 or 48 kHz files. All I hear
is a slight pop when the pitch changes between exactly 1.0 and >1.0,
otherwise playback is smooth and clear, even at varying pitch. This is
on a MacBookPro2,2 with 10.5.8.
One thing you could try is to use the system-provided OpenAL framework
instead of the one that comes with Pipmak (which is there because OpenAL
was only included in Mac OS from 10.4 on). To do this, right-click
(ctrl-click) on the Pipmak application and choose "Show package
contents". Navigate to Contents/Frameworks and move the folder
OpenAL.framework away (to your desktop or somewhere else outside of the
application package).
