Hallö,
I want to change the damage sound in 1.3.2. That's supposed to be the alpha sound. So if you die or get damaged.
Although I have never played in the 1.3.2, but in the newer versions, this is (only) by texture pack. I searched for a short time on YouTube and was also looking for, next time so ask the search engine of your choice ;-)
You'll need to create a resource pack for that and simply swap out the sound files you want.
