Update flash player.External speakers fail.

I use iMac OS 10.6.8. I updated today to the lastest flash player update 100.9.900.152 and since then my external speakers dont work. (Model Logitech Z-10). Also, my Click-to-plugin plugin doesnt work either although it is set to work and enabled properly. Everything worked fine until this update. So, how do I fix this, OR how to I get to the former state I was before?Can I rool back to the former Flash version??

Thanks in advance
