Title: Survive from IE9 throwing "Not implemented"

Apparently IE occasionally throws "Not implemented" from `new Audio()` Behavior was encountered when runnin IE9 and Windows 7 on Sauce Labs cloud. Other reports of this issue relate to Windows Server 2008 or Windows running in a VM.

I'd expect it is safe to turn of audio completely in case `new Audio()` explodes.
