Audio doesn't play on iPhone devices??

Hi,


I'm having a very strange issue with audio after exporting for YouTube and uploading.

When you watch back with an iphone the music in the clip is ok but when the person speaks only static can be heard.

The same clip has normal audio when watched on a computer.

Here is a link to the clip.. try on a phone and computer to see what I mean: ***link removed***

This is a known problem with YouTube when feeding low resolution devices. It happens because the audio sample rate is too high for older devices. You can use Compressor to make a more heavily compressed version for these devices.

When I try low res version on youtube using computer the sound is ok...do you think that the sound should not work there also?

Forgot to mention: this issue has only appeared since I started using a lapel mic attached to the canon 5d rather than the on board mic.
