Steve, either the file has audio or not. Playback volume is not determined by the file/export process. I'm not aware of any default mute/unmute in Magix export files.
I'd be looking at the player setup. How are you "unmuting" the audio when the file is playing?

@Steve-Purcell Hi & yeah i second what @AAProds says, if you can un-mute the movie in the player then it has nothing to do with either the movie clip/file itself or MS, It must be a player setting,
@AAProds is correct but if you right click on the offending track/s you should be able to see 'Show audio waveform' in the drop-down Menu which should show you visually if there is any audio there. It is even easier to see audio if you have the audio placed onto separate tracks. If there is already audio on the track but you are not seeing or hearing it, right clicking the file with the mouse should bring up 'Restore original audio' in the drop-down box. If that is not in the selection then you are seeing and using the original sound track of that clip and as Al suggests, there is no audio.
Out of interest, is this video file clip from a smart phone? If so it may very well have a variable frame rate and may be the cause of the missing audio. If that is the case then the file needs to be converted to a constant frame rate using a free downloadable program such as Handbrake.

@CubeAce Variable frame rate being an issue?, I read that so often on here & the Vegas forum, accepted some frame rates are really wild, really variable but i have always used a phone to film, looking at my clips 90 - 100% of the time they're variable,
Given that a huge proportion of people are now filming with their phones & have been for 10yrs+, surely the makers of these editing programs have looked into this variable frame rate issue, ?
It may be that in part a lot of the decode encode formats are not licence free so not implemented by Magix and if the fees are too steep, may possibly not be offered. There are a lot of variations that are phone model specific as well to suit a specific sensor, so the variation could quite extensive. The problem is one of static movement within a frame. No movement, no additional frames are used. If the program can't see the frame information or interprets it incorrectly then the audio can't stay in sync. In theory it could start too soon or too late.
There could be other explanations though. First it would be good to find out if there is audio when played in a normal video playback app.
Another thing is sometimes I've known particular cameras to have the missing audio on a previous clip and where the video may be chopped up into 4GB chunks if recorded on a camera that uses the fat 32 file system. Odd I know but I've seen that on other camera forums. Normally it is not that large amount of missing audio. Between 5 to 10 frames but if in the middle of say a musical performance, can be audible.
It will be nice to get more information on the problem rather than speculating.
