No audio playback when importing AVCHD video from my JVC Everio camcorder.  I am using MEP v17.0.3.183 in a Win 10 environment.  I downloaded the MPEG-4 FULL Codec Upgrade, with no change in audio.  Importing audio-only media (.m4a) plays the audio normally. I imported the same video into MEP 16 and the audio was there as expected but I prefer and intend to use v17 going forward. FYI, the file extension of the video I am importing is .MTS. What am I doing wrong? Thank you in advance.
