Eliot Miranda uploaded a new version of Sound to project The Trunk: http://source.squeak.org/trunk/Sound-eem.76.mcz

==================== Summary ====================

Name: Sound-eem.76 Author: eem Time: 1 December 2020, 4:41:34.045008 pm UUID: bc35632b-366a-4d24-81f7-024beb3dbda7 Ancestors: Sound-eem.75

Fix a bug in SoundRecorder so that the following works:

[:r| r resumeRecording. (Delay forSeconds: 5) wait. r playback] value: SoundRecorder new

Arguably this should work too:

[:r| r startRecording. (Delay forSeconds: 5) wait. r playback] value: SoundRecorder new

i.e. startRecording should set paused to false. But this is a change in API that could affect clients so I'll oput the suggestion out there and leave it to others to judge.
