whenever I put sounds in...

In any wads i ever make when I put in custom sounds in a character wad that have a name like se_a1 and DIRECT IT DO USE AS A SOUND in the S_SKIN5 it replaces EVERY SOUND in the game with sonic's thok sound!

This is what I put in the S_SKIN5:
dsjump = se_a1
And then when I add the wad... all the sounds are thok sounds!
I MEAN ALL! Including the checkpoints and the goal and the spin and everything... how do I fix this?

So, you're trying to replace the jump sound for that character? I would just do this:

-Rename the sound effect to DS and then the first four letters of your character's name and then a number; ie, if your character is named Bowser, name the file, DSBOWS1.
-Make sure in the S-SKIN, it says DSJUMP = whatever the file name is.
-Make sure that the file is a wave format file, 8-bit mono.
-Make sure the file is saved as doom wave.

Try that.

Sound effects MUST be prefixed by DS, like DSJUMP.

OHHH!!! I DIDN'T KNOW THAT!!!
I will do that right now because that THOK sound was so annoying:
Commanda kills me and then the game over sound is... thox!
I can fix that!
Locked... To me!
