Hi Chris, Regarding the sample rate problem on older iPods, I would try to find an audio project that works properly on an iPod Touch 2G and see how its setup code differs from that in PdAudio. Other than that, I'm afraid I don't have much of an idea because I don't know much about iPhone development and I don't have any ARMv6 devices to experiment with. A number of people seem to be interested in this problem, and so I started a new topic at pd-everywhere in order to create a place where people can meet up and exchange notes: http://noisepages.com/groups/pd-everywhere/forum/topic/libpd-and-armv6/ Best, Peter
