Headphone playback volume

Apologies if this has been answered before, I’ve tried searching for answers several times in as many ways as I could think of and always find a different topic.

When I playback tracks through any headphones, the volume takes several second to get from almost mute to normal. If I then immediately play back that same section, it stays at normal level throughout. If I then make an edit and resume playback, the volume is all the way down again and I have to keep playing back the same section several times until the volume gets back to normal.

Any ideas?

Possibly Windows Enhancements ?
