I am editing a series of MP4 clips shot with a Canon Vixia, and for some reason, Premiere Pro CS6 will not play the audio on a few of the imported files. All of the clips were videotaped with the same camera. I know that there is audio on the clips in question, because it works fine when they are opened in Windows Media Player. I have deleted and reimported the faulty files, to no avail. I noticed in the online discussions that several others have had this problem; but I haven't been ablet o find an online fix thus far. I would greatly appreciate advice on this!
I have a Canon Vixia HFS100, which saves AVCHD files to an SD card... exactly what model is your camera?
If you are copying from an SD card to your hard drive, read these two links

It's a Canon Vixia HFM50. All files are already on my hard drive and an external hardrive. I have successfuly imported and edited dozens of files with the same format in Premiere Pro CS6. This is the first time that it's having trouble reading the audio. Basically, it will play the clips in question for a few seconds, and then the audio quits and I get the conforming error sign.
Yes, they always worked before. I have edited several hours' worth of clips filmed with the same camera. This is the only time that I have encountered this problem with faulty audio. Each faulty clip has an error sign that reads: "An unspecified error occured while performing a conform action on the following file..."
I have noticed that several others have posted discussions referring to similar issues with audio not working.

It looks like I've fixed the problem by converting the files to .mov files, using a free video converter from Wondershare. Apparently, others have had problems importing mp4 files -- though this is the first time that I've encountered such issues with the audio. Here's the link to the article and software download info: http://www.wondershare.com/mpeg/mp4-adobe-premiere.html. Hopefully, this will be helpful to other people who run into the same issue.
