Google Chrome Youtube Sound error. Video Link inside

Hello experts,
While I was watching a YouTube video on my Chrome browser, I turned up the volume slider up to 95% on the YouTube player. However, I can't seem to adjust the sound bar. A dotted box will appear around the sound bar when I try to adjust the slider. I can't move the slider to more than half of the volume level. Everything works fine on my computer except for this. Can someone please provide some resolutions to my problem? Thanks.
