Why the audio poor on Html5 ?

My game almost finish, and i'm now testing it on many Pc,s, In some Pc's the Play sound at position or at objects will play all around the layout and you can hear the sound from every where.

I don't know why, but if this is a common problem i will delete this events and replace it with normal play sound.

Thank's for any help

I personally haven't had any issues, but ive only used it a little bit. It may be in how you put in the events can you post a screenshot

Sound positioning on objects works upon audio properties. Try to experiment with "distance model" and "roll-off factor".

Positioned sound requires Web Audio API support, and some browsers like IE don't yet support it. If it's not supported, positioned audio will play back like ordinary audio (full volume, no panning). This is documented.

Thank's for help and clarification.
