No SOund Flash with Youtube
I installed PCBSD several times and each time I encountered the same problem, when opening a webbrowser with flashplayer I had no sound.
I spend weeks trying to solve this problem untill I found the answer to this problem.
I have a rather big USB hub and the problem was caused due to a plugged Microsoft Webcam ...
Once unplugged and rebooted everything worked as should
If you ever have such similar problem with flash and no sound and if you have a webcam or such connected this could be one of the simple solutions to this problem
Just wanted to let you know if you encounter a problem like this
