I recently reinstalled my operating system Suse 10.0 and now flash player will
only play videos it won't play the sound on youtube.

I recently downgraded my flash player from flash-player 7.0.70.0.1 i586
to
7.0.25.0-4 i586 and still there is no audio.

Problem solved

I found the solution. The only thing that worked was adding the mozilla
repository to Yast then downloading the newest version of flash-player in
software management.

Here is the link to the respository information:
