LPCM audio will not import from camcorder into Live Movie Maker or Live Player.

Recently purchased a canon camcorder (Vixia HF G30).  Naturally, wanted to test out the highest setting   (Video-AVCHD @ 59.94 fps,   Audio-LPCM).  Imported the file using the canon import utility app.  File imported fine, (no error messages).  Played the file, Video portion played great,  but no sound.  Looked at the file properties (detail),  no audio information present.  Doesn't look like the audio imported.  All other clips shot with other camcorder settings import and play correctly, just not the LPCM audio.   I have searched for days now and cannot find solution.  I am running Windows 7 64 bit and Live Movie Maker, not the 2012 version, tried that, inadequate video card for 2012. Uninstalled 2012 and went back to Live.  I have tried Microsoft import utility, same problem, and I have tried importing straight into Movie Maker, same problem.  Video imports fine, LPCM audio does not. Help if you can.    Thanks.
