Summary MESS-specific 06034: apple2gs and clones: improper startup sound
Description The startup sound of an Apple IIGS uses a volume decay technique with the 1-bit DAC output. MESS doesn't handle the trick at all. Other IIgs emulators however, do implement a DAC emulator that properly can handle this.

Audiofiles describing this MT report can be downloaded below for comparison.
Steps To Reproduce 1. Start apple2gs or a clone

I can't hear it in the second video; can you provide a better video for reference?

I updated the second video with one that has some more volume. Go to 13:12 of that video, please
