I have my keyboard sounds on. When I activate Siri and deactivate it and pull open a message to text, the keyboard sound is probably 10x as loud and continues unless I stop typing for maybe ten seconds. Does this happen to anyone else?
Yes, same here...also with sounds if they occur during the same time. I'm sure it's an OS bug that will be addressed with an update.
There are still quite a few bugs that need to be worked out in iOS 5 anyway.
