This is a still a major problem for me across a couple of BigBox builds, if the attract video is just starting playing when the game is selected the sound will continue to play in the background once the game starts (mainly for MAME). Seems like an issue that should be fixed/fixable without needing 3rd party software, although I recognise it may be linked to the theme I’m using (CoinOp and CoinOp Redux).
Anybody have the same issues and has found an easier solution?
