Crash in OALSource::DoRender()

troysandal

We've been complaints from customers that sounds in our game suddenly stop working. Below is the only stack trace I've seen which could potentially be related though I'm still digging for more. This is a hard crash obviously versus the game running with no sound, but perhaps it's related.

Anyone ever seen this?

We encountered this, sounds stopped suddenly on the iPad mini. Except for a game made with adobe flash, sound for all other games and apps stopped working and won't start again. The device was updated to iOS 7.1.1.

There were incidents before where IOS device ran out of SoundChannels to play multiple sounds, it used to crash, so the default behavior was changed that play method returns nil if all sound channels are busy and sound can't be played.

Also which Gideros version you are using?
in one of the older version there was also a bug, a delay of releasing channels, thus if many little sounds are played constantly you could run out of sound channels periodically.

2014.01 is the version we are using. We do play a lot of sound simultaneously but we're checking for nil and moving on if a sound won't play. Would we be affected by this bug or should it be fixed in 2014.01?
