So I'm remotely accessing a friend's server and while watching streaming video, neither the scrubbing slider nor the volume slider do... Anything. And the audio is SUPER quiet. Attached is an image of my browser window, relevant areas at least, showing that the bar is not showing a timestamp even though the video has started playing for at least 10 seconds. Also, while quiet, I can assure you that audio was playing at the time of the screenshot, despite the slider being completely down.
