How to restart services like youtube (sound) and usb (flashdisk)

Sun Oct 28 01:23:07 UTC 2007

Hi,

Once in the while my youtube (firefox/flash) will have no sound.
This will usually happen after returning from a screen saver.
Then, it will work again after exiting firefox (and sometimes
 rebooting).

I tried to restart alsa-utils with no success. Is there any
other way?

Also, I am using an USB cable modem (Sci.Atlanta 2100).
Sometimes, the system will not recognize the USB disk.
Is there anyway to restart the USB service?

regards,
