tomi71 If your audio was lagging then you were most likely playing on a device that wasn't up to specs.
Or, there is a known browser issue where when you play positioned audio for the first time there will be a pause while the sound information loads up. You can work around this by playing the positioned audio for the first time at the start of the layout at something like -1000db. (You should do this at before the player starts the game, like on the title screen layout for example). That allows the positioned sound info to get processed by the browser at the start of the layout without the player actually hearing the sound.
