1752656245 (hwiu) returned from AudioQueueStart

[coneybeare]

My app uses AVAudioPlayers for local sounds in addition to AudioStreamer for remote sounds.

Audio streamer works great by itself, but after playing a local sound (using the hardware decoder) an AudioStreamer cannot be instantiated and returns error code 1752656245 (hwiu)

http://developer.apple.com/iphone/library/documentation/musicaudio/reference/audioconverterservicesreference/Reference/reference.html

Looking at the docs doesn't really help in this case, or at least I don't understand enough about what is going on to figure it out. Is this an AudioStreamer bug or am I doing something wrong?

for lack of a better solution right now, I added a hardware preference override to the audioqueue in "createqueue" line 1494

// set the software codec too on the queue.
UInt32 val = kAudioQueueHardwareCodecPolicy_PreferSoftware;
OSStatus ignorableError;
ignorableError = AudioQueueSetProperty(audioQueue, kAudioQueueProperty_HardwareCodecPolicy, &val, sizeOfUInt32);
if (ignorableError)
{
    return;
}

I have the same problem. Thanks coneybeare.

I feel like you should probably add this to a fork and request it be added into the main code base.

Yes , Playing multiple sounds doesn't work. thanks for the fix. This patch should be officially committed for this issue.
