fedora 18 sound problem pulseaudio

after installing fedora 18 KDE and have it updated, I got this problem and solved it by workaround :

open command line interface and type :

pulseaudio -k #to kill the process

nohup pulseaudio -vv & > /dev/null # run it again and even you disconnect from the terminal, it still running

 

well, I have no idea why the reboot didn’t kill it (or may be it has been respawned after reboot), but anyway it worked and hope it helps :P
