I can confirm that the wavs do crash the engine here on Windows 10 for whatever reason.
I opened up the bombbeepmain.wav into audacity, and then exported it with no changes. It produced a wav which didn’t crash the engine - it plays properly. So you should probably download audacity (free) and export your wav files through it to produce versions which play properly.
Thanks Pkeod. Ableton exports in your desired bit-rate so I rendered them again without audacity.
The manual states
Should be set to a sound file in your project. The file should be in Wave or Ogg Vorbis format with a sampling rate of 44100. (See WAV - Wikipedia and Vorbis - Wikipedia for details).
It would seem that bits per sample should also be 16 to ensure that WAVs work correctly.
We should detect and warn about incorrect bits per sample and frequency when building, or better yet handle it properly at runtime. I’ll open a ticket when I get to the office.
