This is as expected. What Chris says is no surprise. If you render the output to a .wav file it is captured as a snapshot and the sample rate no longer has any effect (other than to change the overall playback rate). The problem others were trying to explain is that the synthesis patch is not independent of sample rate, so using the same Pd patch at different sample rates will produce different results. If you're recording it the problem doesn't exist.
I am not sure if I understand this distinction correctly. If I use Pd at 44100Hz to generate a high frequency wave that aliases, and save it as a 44100Hz wave file, shouldn't that wave file be subjected to different aliasing if I play it back at say 22050Hz? What about if I upsample it to 96kHz? Will the aliasing weirdness disappear if the tone I played was below 96kHz? Or is it somehow baked into the wav file. I think I am out of my depth here.
