Trouble Getting Segment Zero (0) to Play on AP-8

[Spooky Dad]

All other of the default sounds on the AP-8 play, except for the one sound I loaded in Segment 0.  When I hit the play button on the AP-8, the sound I recorded plays.  Any ideas on what I am doing wrong?

It runs as intended on my Prop-1/AP-8 setup.  Do you have the WRB wire plugged in correctly?  I had it backward at first.

[Spooky Dad]

Yes.  To be clear, its only segment 0 that attempts to play (the speaker's humm a bit and then go quiet) and fails.  When I change the code to refer to segments 1 through 7, all of those sounds still play. 

[JonnyMac]

Sounds like segment 0 got erased -- you might try re-recording it.

[Spooky Dad]

I'll rerecord.  When I hit the play button manually, I do hear the sound I recorded. 

[JonnyMac]

I'm baffled... must be aliens.  Or space monkeys!   :D
