51 e2687188aea5 The evil Apple iOS 5.0 OpenAL regression bug strikes again. A user managed to encounter a case where the OpenAL buffer never unqueues and the workaround gets stuck in an infinite loop which results in the app getting killed by watch dog (crashing). I've added a timeout that will abort the unqueue attempt after 200 milliseconds. But if the buffers could be unqueued but the timeout we picked is too short, then we will regress back to the original problem. All iOS 5 audio users need to test this to make sure their apps don't break again. Please remember to file your Apple bug report if you haven't (bug:10145018), test with iOS 5.1 beta to check for new problems, and report results as necessary.

51 e2687188aea5 The evil Apple iOS 5.0 OpenAL regression bug strikes again. A user managed to encounter a case where the OpenAL buffer never unqueues and the workaround gets stuck in an infinite loop which results in the app getting killed by watch dog (crashing). I've added a timeout that will abort the unqueue attempt after 200 milliseconds. But if the buffers could be unqueued but the timeout we picked is too short, then we will regress back to the original problem. All iOS 5 audio users need to test this to make sure their apps don't break again. Please remember to file your Apple bug report if you haven't (bug:10145018), test with iOS 5.1 beta to check for new problems, and report results as necessary.
