Crash playing MP3 for background music

by Joe Williams · in iTorque 2D · 12/12/2010 (5:22 am) · 3 replies

I'm playing a small MP3 as my background music. It works fine in the simulator, but it's causing a crash on the device. The error in the debugger is:

Program received signal: “EXC_BAD_ACCESS”.
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).

And Xcode then highlights the middle line here:

result = AudioFileReadPackets(CurFileInfo->mAFID, false, &numBytes, THIS->mPacketDescs, THIS->mCurrentPacket, &nPackets,
inCompleteAQBuffer->mAudioData);
AssertNoError("Error reading file data", end);

Anyone have any ideas as to why this would happen?

The code that is playing the file is this:

%filename = "~/data/audio/STTMain.mp3";
$musicStreamHandle = startiPhoneAudioStream(%filename,true);

I just got the 4.2 SDK and a 4th gen device, so I will try testing this a little later to see if I can replicate the error.

Is that possibly the issue: the 4.2 SDK? My main music track isn't very long, I can just switch it to a wav and play it in engine if rolling back to 4.1 is the only way to fix this.

Could very well be due to something deprecated or a change to the way the sound engine works. I'm almost up and running, might have to tackle this tomorrow.
