Don't know the Roval wheel but 24 spokes and apart from a bit out of true- the remaining 23 will hold together for a while.

But a wheel that breaks spokes this soon after purchase (Take it that it is a newish wheel) possibly has some other problems on it. Get the wheel spokes detensioned before retrue and keep your eyes open for other damage to the wheel. Cracked rim may be a possibility or the adjacent spokes to the broken one may fail due to the extra strain they have taken.

That of course is the worst scenario- but a broken spoke for no apparant reason would get me worried.

Unless of course you are an animal and have just broken the spoke with the amount of power you put out. Son-in-Law has this problem so we keep a spare rear wheel built up for him and every time I get his bike in for checking- I check the spoke tension by ear. A dull thud on a spoke instead of a ring means that he has been out with the fast boys again on the after work commute home so change wheels and retrue the one he has knackered---Again.
