This is usually caused by having DD 5.1 SS Audio in your files. If you create a New Project with the AVCHD Preset and choose DD 5.1 SS, this will allow the Clips to line up.
You can edit in Timeline View Mode, as is, but you will need to scroll to see the Audio Tracks, where the Audio from your Clip has gone.
Thanks Hunt. I found
the correct pre-set. I can see this will have a bit of a learning curve, but I'm on my way!
Since DD 5.1 SS was added by many cameras to AVCHD, this has tripped up many before you.
As mentioned, things are OK in the Timeline View Mode, but the Audio will be a bit further away, than it will be, when you choose the proper Audio in the AVCHD Preset.
Good luck, and we are all, always learning.
