Delete XMP files

Okay, so my problem is that i cant get audio on my MTS files in Premiere. Neither in the preview window or when i put them into my sequence. I have tried with Stereo, 5.1 and multichannel but nothing seems to work. So i went to the my local video and photo store and asked for their advice, and they told me that i should delete the xmp files. Firstly i cant find them anywhere and secondly i do not know what they do! Anybody here who can offer me some help on the matter

 

Thank you!
