No Sound and Fast You Tube

[Jonathan Moore]

Hi

I'm having trouble with my sound nothing plays on You Tube but when I turn
up the volume
I hear static. I found this in the forums
https://forums.freebsd.org/threads/53712/ .

Plus You Tube video plays fast and I really don't want to install flash.
I'm
using Firefox.Running FreeBSD 10.3 RELEASE.

Thanks,

Jonathan
