Audio playing when you hover your mouse needs to go

The video previews itself, great idea. I have nothing against it until recently. Now, when you hover your mouse on a video, it plays the video with the audio, and to make it even worse, it plays the same volume the video itself plays it on. I don't know if this was a feature in the past, but if it was, I must have had it turned off. Now it gives you the option to turn it off, but once you change tabs or reload the page, it's back on. Every time I go on YouTube now on my pc I have to make sure my volume is low, and I turn off the volume on preview every single time. I don't know how many times I had my pc on max volume and had some random loud video play. Some videos need to be on max volume, and some need to be on a lower volume. They could easily fix this problem by giving you the option to turn off audio from the video preview itself. The only way now to turn off audio playing on video preview is by turning off the video preview itself. Video preview itself is a great feature that I don't want to turn off, but adding audio to the feature without giving you the option to turn that part off ruined the video preview.
