No audio from skills

There is no audio from my attack skills, but I can hear everything around my character. I reset the audio, computer, and game still no sound.

which class ?

If you’re using the Korean VO DLC, try uninstalling then re-installing it in Steam. When viewing Lost Ark in your library, click on the “Manage my DLC” button in the bottom-right, below the Achievements.

I have only checked my Gunslinger, Sorc, Soulfist so far.

Thanks that fixed the problem for me.
