I have just upgraded from r190 to r200 and I got an audio error that will crash the game and give out stack trace complaining "Failed to set the 'volume' property on 'HTMLMediaElement': The provided double value is non-finite."
This problem does not occur in r190. I have reverted back to r190, re-exported the project as node webkit and see that the game runs without a problem.
Attach a Capx
http://www.mediafire.com/download/11ucq ... ioBug.capx
Description of Capx
The capx slowly turns down the volume of the music, using a global variable. The formula used in set volume function is -log10( 100 / ( x / 0.9*100)) *33.2, where x is a variable. This is used in my game to turn down the music or slowly fade away a sound effect. (ex. when you walk away from a waterfall) Once the volume is all the way down, the game will output the stack trace error.
Steps to Reproduce Bug
Have a countdown variable that slowly decrease and use it to set volume using the formula given above. After the variable is less than a certain number, the game will crash. See the event sheet of the provided capx.
I have been trying to reproduce this in several other ways, such as giving -infinity to set volume function, but it does not seem to crash.
I got this stack trace:
TypeError: Failed to set the 'volume' property on 'HTMLMediaElement': The provided double value is non-finite.

The game should not crash, as it does not crash in r190.

I see that r198 got a bug fix "Audio: setting volume did not work correctly in r197", so this implies the internal code has been changed in the function. Perhaps, you could add some sort of parameter safeguard to prevent the function to crash the game just like back in r190 ?
