>(a) The sound-in-event-recorder bug *does* occur [in 3.9 7067].
>But it's slightly

>OLPC, the *pitch* does not change. So it is not a Donald Duck sound.

>(b) Also, the same bug now (i.e. in 3.9) also occurs in the vanilla
>SoundRecorderMorph! (In the OLPC/Mac image, the vanilla
>SoundRecorderMorph produces good playback on the Mac -- it's only the
>use of sound within an EventRecorderMorph that's problematical. In
>the 3.9/Mac image *every* SoundRecorderMorph use has this problem.
>But again, the overly-fast playback occurs *without* a pitch rise.)

>So evidently 3.9 went "final" with the SoundRecorder completely
>broken on the Mac.
