AL_INVALID_VALUE on Unity iPhone

Hi,
I am getting this error: AL_INVALID_VALUE, which according to other posts in the forums relates to audio levels or trying to play a sound before it is loaded.
In my case I am trying to load 1280 very short sounds from Resources into 5 audio sources (256 per source). I can find one audio source that seems to cause the error by not loading sounds for that source. Then I restart Unity and the error is back and I can again find the new source that is creating the error. This is the code that loads the sounds for each audio source (although this is not where the error is being generated):

function Start () {
clips = new AudioClip[256];
for (i = 0; i < 256; i++) {
clips = Resources.Load(insName+i.ToString());
}[/code]

I finally tracked it down - there were 16 samples with an audio bit rate of 1411200. I saved them from Audacity and they now have a bit rate of 705600.
Problem solved - yeehah - only took about a week.
Maybe there should be some error checking when Unity imports resources?
