<p>I haven't been using Sony Vegas too much, but this has never happened to me before...
<img src="https://i.sstatic.net/reZJF.jpg" alt="enter image description here"></p>

<p>All my videos look like this.. I can playback no problem, but without sound. It's mp4.
What could be the issue?</p>

<p>Thanks</p>

Do the videos actually have sound?  Are they using an audio codec that Vegas understands?  It appears that Vegas thinks there is no audio since no waveforms are displayed.

It's working already.. I had to reencode the videos with Handbrake. Don't know where the problem was..
