every once and a while when i'm on YouTube or Grooveshark, i audio sounds like Metallic Static...

To "cure", i have to Close the whole tab and reload. refresh doesn't seem to fix it ...

Anyone else having this same problem?

The newest update in the Development channel will fix it for you if you want to give that a try. Click on the wrench and go to About Chrome OS, then click on More Info and change the channel to Development. Click on Check For Updates at the bottom.

did as suggested "About/Dev Channel/Update" and so far so good ... have not heard the sound once since.
Thanks for the advice.
