Place the archive in .xonotic / data
Other versions (Versions v2 and v4 is not avaliable): pre-release,first release,bottom v5, v3, v6-v9 
EDIT:
    DOWLOAD LATEST VERSION Reply

.mp3 sounds do not work in this game, but .ogg should. The likely reason for it failing is execution order; the xonotic-data package has a lower alphabetical name than sounds.pk3, so the stock sounds are preferred. Most server packages work around this by naming their package zzz-myfile.pk3.
It would also be worth adding a version number to the pk3 incase you intend to make further revisions, and since this is a local replacement, you could go for a file name like this:
zzzz-kota-sounds_v1.pk3 Reply

it would be great to add support for .mp3 format, but now .ogg works Reply

I like some of them, especially Laser's one. But there is a trouble with "grenade_fire.wav", its sound is overloaded. Take a look on the screenshot and compare your version with default one:
