Since this is clearly a question about a video file, I have moved your post to the video section of the forums.
But, exactly which video software do you have? If it is a Vegas product please see this post and follow the advice given there.
If you have any of Movie Edit Pro/Movie Studio, Video Pro X or VideoEasy you are in the correct forum but we will need to be told a lot more about your computer (please see this post). Also, more detailed information about the actual video file you ahve would be very useful. This tutorial will show you hoe to create and post here a detailed analysis of your file.

Hi
. . . . When I import an m2ts there is no sound. . . .
This would suggest the audio is encoded Dolby AC3 Stereo or Surround sound, this format was removed from Movie Edit Pro due to licensing issues.
The audio stream needs converting to AAC stereo with a video converter such as Handbrake or Avidemux.
Is your PC spec still:-a
Cpu Intel(R) Core i5-2400 CPU @ 3.10GHz"
OS Microsoft Windows 10 pro 64 bit
RAM 8 GB
Graphics AMD Radeon(TM) R7 360 Series 1440x900

Thanks, John. I got Handbrake and it works fine, except slow. Unfortunately, I discovered that my camera (Sony HDR-CX130) cannot be set to record in MP4. To avoid converting clips that I do not need, I have to review each one and delete before converting and importing to MAGIX. Time consuming.
Yes, I still have the same PC.

Handbrake, as far as I can tell, always recodes the video, which is probably the time-consuming part. Try AVIDemux, as this allows a straight "copy" of the video independently of the audio, which you can convert.
You can either install AVIDemux or run it in "portable" mode after unzipping it..
Open it, open your file
Video Output: Leave as Copy
Audio: on the main Audio menu, click Select Track and untick the tracks you don't want (try using track 1 to start)
Audio Output: choose AAC (FDK)
Audio Configure: bitrate to 192
Audio Filters: Resample to 48000
Output format: MP4 Muxer
That's it, click the Save button and in a short time you should get an MP4 video with AAC sound which Magix sill import.
If you have any issues, it would help if you could provide a short clip for us to analyse. Post it on Google Drive and give us the link, as the forum software will re-encode it if you post it as an attachment here.

@EditorJim Hi, I'm just curious, I had a look at the specs of your camera online
MOVIE FORMAT - High Definition, MPEG4-AVC/H.264 (AVCHD)
Like I say I'm just curios as to the file that creates -
So there's an App called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish. https://mediaarea.net/en/MediaInfo
After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, Copy & paste the information in a new comment on here 👍

Hi
The Sony HDR-CX130 camera records audio as Dolby AC3 Stereo, it is the only option and due to the removal of the Dolby AC3 codec the audio is not imported into Movie Edit Pro.
The removal of the codec was a result of the Adobe vs Dolby licensing issue and affected many software manufacturers who used the codec.
Magix Movie Studio 2021 and later can import AC 3 audio, both stereo and Surround Sound, however they cannot export as Surround Sound. Unfortunately the computer spec is not conducive to a good editing experience with MMS, it has limited capability to hardware accelerate h.264/AVCHD video
