Angry Birds - no sound after Angry Birds interrupted by text message

Angry Birds - no sound after text message...

iPhone 4, iOS 4

Playing angry birds when the iPhone receives a text message; upon acknowledging or viewing the text message and returning to the game, Angry Birds does not have any sound.

One solution is to power cycle (reboot) the iPhone, but this is overly intrusive. Better way is to restart the Angry Birds application...

Check this out:

"Force Quitting To force an application to quit, Apple recommends that you bring the app you want to quit to the foreground. Then press and hold the sleep/wake button for several seconds, until the Slide to Power Off control appears. Release the sleep/wake button and hold down the Home button for another 7-10 seconds. Your screen will flash briefly and you will return to the main iOS 4 Springboard home page with its icons. This method works for all operating systems from iPhone OS 3 forward, and is the preferred method listed in the iOS 4 documentation.

Removing the Application from the Recents List There's actually a much simpler approach for quitting apps, and that's to use your recent app list. Double-click the home button to display the recently accessed applications. Press and hold any of the icons shown, then navigate to the application you want to quit and tap the red circled minus button. This sends a signal to the application in question that allows it to quit. The application will be re-added to the recents list the next time you launch it."
