No Audio in import from iPhone after 24 seconds

Question

First, I'm not an iMovie expert in the least, but I've been trying to work through it and learn as I go.  I'm having a problem where I'm trying to import video clips from my iPhone, and after I go back and watch the imported clip, the audio stops after 24 seconds.  It does it with every imported clip from the phone, every time.  And, like clockwork, it stops after 24 seconds every time.
I also have a JVC camcorder which I've imported clips off of its SD card, and all those import just fine.  So it's only having the problem with the clips from the iPhone.  I can play the clips both on the phone and in the iMovie import window (before it's imported) and they play fine all the way through.  I only lose the audio after it's imported.
Any ideas are appreciated.
Macbook Pro OS X 10.8
iPhone 5.1.1
iMovie 9.0.7
Oh, one other question maybe someone can answer.  When I connect my iPhone to my mac to import, my iPhone turns its WiFi hotspot on.  This then forces my mac to use that for its internet connection instead of my home internet.  The WiFi in the menu bar still shows connected to my home network, not the hotspot, but I think it's going through the USB connection.   When it's connected and I turn off the hotspot, the phone will then disconnect from iMovie. Is this normal?  Is this how it's supposed to work?  Any way to prevent that?
Thanks!

I had the same problem so what I did is to download a streamclip media free software, search out from google, then when the clip from memory card are downloaded onto computer I open them with streamclip media and then export them in compatible format , there is option on file menu, I don't reme,ber now as I am replying from a cPC, but this works, so save this exported clip and use it in i movie it plays sound.
