Javascript notifications in Chrome -

-

i'm trying make sort of alarm clock web application , noticed having problem audio file wouldn't play , title-bar wouldn't flash if chrome or web application's tab wasn't in focus.

i found answer here saying chrome runs in separate processes or threads, need inter-process programming or something, couldn't find examples how this, find ways pause javascript in background until focus given tab or chrome. obviously, useless, point of application provide notifications while tab or chrome not focused.

the application works fine in other browsers, not chrome. know how can make titlebar flash , play audio file if chrome or web app's tab not in focus?
