.MTS files no sound

The problem for me was the way I imported the video files from my Sony camera. It seems like it missed some data. Some MTS files had sounds, others didn't. Quicktime did play the sound but exporting from there and importing in Premiere didn't even do the trick.

This was my fix;

I copied the entire content of the disk do my computer and then I opened the files like this;

PRIVATE (map) > AVCHD (file) > right-click > show package contents > BDMV (file) > right-click > show package contents > STREAM (map) > import (I dragged) into Premiere.

Thanks to this youtube video. But I added the steps just in case in gets taken down.

Hope this is helpful to someone because it drove me crazy for the pas three hours.

I solve this problem by selecting the clip (or clips) in the project and then right-clicking - then select, "New Sequence from Clip".  Creates the clips with auido in the timeline.  Selecting multiple puts them all on the same timeline.

I'm having the same problem - it showed up with one of the updates (I wish I had paid attention to which one) and now every time I import video it is a nightmare.  Adobe will no longer import the main folder from any of my video cameras.  I have to get into AVCHD, then BDMV, and then import the "Stream" folder.  But then I have missing audio files.  Consistently, I get the full audio from one camera and partial audio from the other two.  I have deleted my cache, made the files "offline" and then relinked.  It still doesn't work - but even if it had worked, this is a waste of my time.  I want to be editing video, not searching forums for fellow users to do the job that Adobe's team should be doing.  Time to get this fixed, folks - the rest of us have jobs to do.

I have the same problem now - nothing helped. Media Cache emptied, rename "common" folder (Youtube-Tip), import via Media Browser (I can't even find the file, it's not being shown).... I have a deadline, Premiere updated itself (I changed the automatical updates now), EVERYTIME Premiere SUCKS and has bugs, this makes me angry, that I lost half a day. 

That second scenario sounds like you simply didn't have the Source targeting set for an audio track. After you have a sequence open in the Timeline panel, any further media you add from the Source monitor needs to have Source targets set on the very far left of the Timeline control header block for an audio and a video track.

I'll bet you have a blue video block on the far left, but no blue audio block. Simply click on the block for the appropriate audio track, it turns blue, and now the audio will also come with the video.

I found a solution for me, which is probably not the problem of many, but I'm writing it down here in the offchance anyone else has this setup:

I am running Windows Server 2019 as my primary OS, where MTS Files do not work. I installed Windows 10 2004 in a VM and installed Premiere there, and it worked again.

jstrawn - Thank you so very much for that information. Much better than jumping through the hoops trying to extract audio, or unlinking, relinking. Your suggestion worked wonderfully.

Using a different editing software could Resolve your issue. Premiere is really starting to piss me off.

The renaming doesn't work for me. My MTS files simply do not play audio. It won;t link. This is unacceptable, ADOBE. You guys are making a KILLING with these subscription packages and now pro's like us are taking it on the chin. Sort this nonsense out, NOW.

Don't try to tap dance a workaround dialog with me...fix this remedial issue or I will drop you like a sack of trash and edit with another software. Your stuff isn't that good, trust me. I'm not afraid of another UI. Let's get this going on the double. This is OUR money paying for this service and keeping your team of fiddlers employed. Let's get serious here.

I know I'm a little late to the party but I have had this problem a number of times with .mts files. They import fine, and when i play them in the preview monitor the audio is definitely there. When I go to file properties, the audio info is definitely there. The problem lies in me trying to drop the file into the timeline, the video will drop down fine, but I can't even see the audio bar drop onto the timeline. Sometimes it has simply been because the file hasn't had a chance to index or load into the system entirely. Tonight though, i closed the sequence and opened a brand new sequence within my project and then dropped the file into the timeline and it worked perfectly. My thoughts are that the sequence settings from my first sequence somehow clashed with or cancelled out the audio from the .mts files. All three camera angles I am using are the same, so it may just be the fact that it's .mts clashing with .mov. No idea. Just thought I'd throw this up as an alternative. Next time I'll make sure I drop the .mts file into the sequence before other video.
