Sound Troubles

Hi everyone;
This is my first thread after installing OpenSuse11.0. I do not have any sound coming out of my machine. Also, I am not able to write in Arabic in Yahoo. Another issue is how about the voice chatting in Pidgin.
Thanks in advance.

Reference your sound problem, try working your way through the openSUSE audio troubleshooting guide: SDB:AudioTroubleshooting - openSUSE

As for the arabic output I went to Keyboard>Layouts>+Add>Arabic
Even this can be used to install different lang outputs.

Now, it comes to the voice chat softwares that enable me to utilize chatting on Yahoo and Gmail, still I did not any reply.
Would u please give me detailed steps if there is any package came with the Distro.
Thanks for your help.
