If you’ve ever had 30 Chrome tabs open and can’t figure out which one is playing some audio (guilty),  has some good news. The Google Chrome Team is working on identifying tabs that play audio to exclude them from the list of tabs to discard when memory runs out.

In a first step, they’ve added a small indicator on top of the tab favicon to tell when a tab is actually playing audio.
Youtube video work only if you joined the HTML5 trial at www.youtube.com/html5

You can already see it in the last chromium build (download-chromium.appspot.com).

It hasn’t yet hit my Canary nightly, but I’m really looking forward to this one.
