Alliteration is a powerful tool, used sparingly and in the right way. Certainly you don't want to sound like a comic book, recounting the raucous rows of right and wrong that ring readily round, or whatever. That gets old REALLY quick. But you might consider some of the following ideas:
"He cracked rusty caps and fractured glass as he crunched through the gravel..." This concept conveys the sound of the event it's describing - the sound of glass and gravel under foot - without having to write actual sound effects.
It is a common tool as well to use alliteration in names, such as the classic Morkoth, Mordor, Sauron, etc., as well as the more valiant sounding Arwen, Aragorn, Galadriel, Elrond, etc.
Finally, don't forget to include assonance (like alliteration for vowels) in your mix, to produce more fruitful results:
"A cream dove cooed musically in the sussurous gusts of dawn."
This is a blend of "k" sounds, as from a dove, but softened by "S's" and the schwa vowels and "u" sounds. It is a little more reminscent of the scene than...
"A white songbird made chirping noises as wind blew while the sun came up."
That's not only more of a report, but the sounds of the words clash with the beauty of the ideas. But, hey...that may sometimes be the effect your looking for, as in the irony of something beautiful clashing with a hangover, for example.
Just remember that the purpose of assonance, alliteration, and meter/prosody are intended to give writing a lyrical, poetic quality, rather than making them cartoonish.
