also happened with snes9x core

Hi, sorry this took so long to get looked at. Thanks for including all this debug info!

This is the key line: [W] using null output device, none available

There doesn't seem to be any audio output device available. Our code, unable to handle the situation, crashes. When this happened, did you have any kind of audio working on your computer?

[athairus]

The entire frontend and backend have been rewritten. If this problem happens again, feel free to make a new issue. Closed!
