My sample rate is 44100, and I didn't change it since the Snow Leopard (where ChucK worked without any problem).
Anyone else having this problem? Or can think of solution?
Well, that sucks.
The only solution I can think of is that XCode may also have been upgraded when OSX was. I'd try recompiling ChucK under Lion. If that helps Princeton/Stanford should probably rush out a updated binary for OSX Lion.
If it doesn't help then Gary, who manages RTAudio (the audio library that we use), may have to dive in. That might be a good occasion to update the version of RTAudio that we use?
Wishing you luck,
Kas.
