Youtube Safari not working - Please Help!

Dear all,

Usually I try to fix all the problems myself but this time it is way off my head. I opened this account with hope that somebody will help me to fix my problem. I have Yosemite, and today i have update Clover to the last version. Right after update, youtube and some other pages with flash content just stopped working. When I open any video from youtube i just hear a strange very short sound and that's it(like the scratch of a vinyl)

Here you can see the errors that i have it in console:

Please Help!
Thank you

I have had a similar issue and the only solution I have found is to use the MacPro 3,1 definition. Happens on my machine with every definition except MacPro 3,1, which is a shame since I planned to use iMac 15,1 which matched my i7-4790k CPU.

I will post back if I find a better solution.
