Okay, asking here because I am utterly stuck. My audio seems to keep vanishing on my internet. Only started happening yesterday. I play a video online - sometimes the audio works fine, sometimes there is no audio. It's completely random. As soon as the audio stops working, it won't start again unless I close the tab I'm using and load the video in a new one.

I've got the new update for Flash, and haven't changed any settings. I've troubleshooted my audio playback, and tried changing playback settings on my internet, to no avail. All other audio isn't affected, so it's not my computer that's the problem. And I have no virus as I've just finished running scans :/

It's happening on YouTube as well as other video sites.

Anyone here have any idea what might be causing this? :(
