I open a project in movie maker and all sounds stop working. I checked the sound mixer and saw that Movie Maker and Google Chrome were making noise, but it didn't show output on my speakers.

The speakers are in my laptop, which is an HP Notebook 2000 running Windows 8.1.

Sound only returns when I restart my computer

I've updated the driver software, made sure nothing was muted, turned up the volume all the way and still nothing.

I saw another thread on this, but it was old and wouldn't let me reply, as well as none of the solutions there worked either.

EDIT: I've found that sound returns about 8-10 minutes after Movie Maker closes
