Play - Auto fade in (unwanted)

Hi S-EH, thanks for help.
I suppose WL7 no have this [sometimes] annoying feature.
Sound Card can’t do that. Sound Card simply plays the contents of the audio buffer, no intelligence aboard.

Easy to test with Justin’s waveform + silence on top

  • Plays with Fade In, PlayStart begins at the first sample of the sine:

The result, FadeIn
.

  • Plays without Fade In, PlayStart some samples before:

The result, no FadeIn
