    PE8 unable to play 5.1 sound from an imported .m2ts


      I import an .1080i 5.1 m2ts into PE8 and drag it onto the timeline.  The video lays out ok and the audio track indicates 5.1.  However, no sound track is displayed and no sound occurs during playback.  The m2ts plays fine from Windows Media Player.  I completely wiped my machine back to factory Win7 HP and the latest MS updates with a fresh install of PE8.0.1 but still no sound.  I've tried two presets:  NTSC/AVCHD/Full 1080i 30 5.1 channel and 1080i 30 5.1 channel with no luck.  What am I doing wrong?


      1080i 5.1 recording is stored on a Scientific Atlanta Explorer 8300HDC PVR STB.  STB is connected via component video and optical audio cable to Hauppauge HD-PVR.  .m2ts is created using Total Media Extreme video capture from STB playback through HD-PVR.  Workstation is a Gateway NV7923u laptop i5 M430 2.27GHz, 4GB RAM, 500GB HDD (300GB free), Windows 7 Home Premium 64-bit.

          Did you create a New Project with the AVCHD - 5.1 SS Audio Preset?


          If so, then the Audio should go onto Audio 1 Track. If not, then it will go to a higher numbered Audio Track, and you will need to scroll the Timeline vertically to see that Audio Clip.


          Also, when you Imported that Clip, did you allow it to Conform the Audio? This ARTICLE will give you some background.


          Good luck,
