So I've noticed that in JB, on both a Nexus 4 and the Note 2, I receive a notification sound whenever I get a new Google Talk message. This is working as expected, however, whenever I open the app and am in the conversation window, I still get the notification sound for every incoming message. Obviously the sound should only be going off when the app is minimized, but it goes off even when I'm in the app. Any ideas? Is this a known bug? My Google Fu failed as I only found posts about changing the sound. This was not a problem in ICS.
