Water Spillage! No sound on MacBook Air!

After spilling water onto my mac’s keyboard, i instantly tried drying the top of the keyboard, straight after i tried to see if anything was damaged, to my surprise, everything was working fine, but as i went to a video of such, there was no sound so i thought it might have just been a bug, i tried the siri on my laptop, but yet again, no sound came out.

The only sound that comes out of the laptop is when it starts up and makes the usual start up sound, but after that, nothing works with the sound.

The internal speakers are selected, still no sound.

I’ve shut it down for the time being so it doesn’t become more damaged, do i have to take it somewhere to fix it? What’s wrong with it? And is it damaged?
