my ballast did that and it was very warm after, i let it cool down for like 5 minutes and sound went away after light kicked on, might help...also make sure all cords are plugged all the way in that will make it buzz also

is it a switchable ballast?

i hope your ballast is dimable because you should only use the size bulb which your ballast is rated for. since it buzzs i would assume it is a magnetic ballast which is not dimable if this is the case magnetic ballasts do buzz but you must also use thee correct bulb rated for the ballast
