Game crash (maybe relative to sound)

Rickyngk

I've found an interesting crash bug.

1. First, run any made-by-gideros app. I tested with "save my toys" (go to level screen), and game42 (go to tutorial screen)
2. Switch to another made-by-gideros app. For example,
+ Open Audio buttons example and play some sound;
+ or , Cerberus at level screen
3. Back to first app.
+ "save my toys" : press any level.
+ "game42": press next button


Try some times, it'll be crashed (100% with "save my toys" vs Cerberus , "game42 " vs Cerberus, "game42" vs "save my toys"). For Audio buttons example, sometimes it does not cause another app crashed, but it can not play sound anymore after switching among those apps.

For game42, I see that sometimes sound channel now is null without any clue

Any Issues like that ?

Currently I'm fixing the bugs reported up to now and I've put this bug to the list. I'll update this thread when I find a clue. thank you

@Rickyngk,

I've tested same behaviour with other sound libraries like ObjectAL and CocosDenshion. With ObjectAL same bug occurs but with CocosDenshion it doesn't. Also there is a probability that this is a bug of iOS 6:

CocosDenshion has a workaround for this bug and I've also used the same way to fix it.

Interesting. Could this be related? I've found starting my game with the media volume set to zero will crash it immediately on my Droid X phone. Even extremely low volume sounds seem to cause it to crash. I had cases where the source of the sound in the game was quite distant, so the sound would be played with a low volume. I have an in-game master volume adjustment, and if that's also set low, some sounds would end up playing with an effective volume of under 1%. By adding code to skip any sound with a final volume of under 5% I prevented the crashes. But now I see it still crashes if the system media volume is zero when I launch the app.
