[whatwg] HTML Audio Element removal from DOM

Tue Jan 17 21:58:11 PST 2012

The issue I'm having with webkit is with running play() immediately after removeChild. Are you hearing an audible pause when doing so in Opera and FF? I believe there should be no audible pause even though there is an event pause and a loop/queue cycle.
