Restart/reset sound drivers/service in Lion

After a couple of weeks after its release, Apple's Lion is by far not the synonym for stability & reliability. If your sound system resp. the drivers crash and you don't want to reboot the machine, just type this into the Terminal. And then ..."it just works"!

sudo kill -9 `ps ax|grep 'coreaudio[a-z]' | awk '{print $1}'`
