[PD] PD on Gumstix - Duplex Audio Problems

Hi PDers-

I have compiled PD (not PDa) for use on Gumstix overo, but I'm having  
a couple of problems getting full duplex audio.

I can do either in or out ok (eg. -noadc), but asking for in and out  
/dev/dsp invalid argument "read/write"
and then switches to out only.

I can do audio in/out on gumstix (using arecord | aplay) with no  
problem, so it seems something specific about pd. I compiled pd-0.42-5  
on the actual gumstix board with gcc.

Has anyone had this problem before - perhaps not with Gumstix?
