No audio after importing! FCPX

I have a cannon T3i, I have been troubleshooting this situation for some time now! After I import into FCP I lose audio, and I have to export it to quicktime, export audio, and then import it into FCP. The reason this is happening is, because I use a rodes external mic. When I record with my T3, and do not use a external mic it imports everything fine. How can I fix this? I need my good audio with my external mic, but tired of taking the extra step importing my audio. Something is going on with FCP! Because when I use Premiere Pro it imports everything fine with no issues! Someone help, so I can continue using FCP.
