Input not working

I was trying to record through a mixer and I think there was feedback. Then i started hearing a popping, ticking noise and it keeps going. It is preventing me from recording anymore because it's not picking up anything played on guitar or mic. My midi keyboard still comes through though. It's continuos like a metronome and it changes a bit when you adjust the recording level. Ive tried changing input settings and nothing works. It only makes sound if I have the 1/4 jack adapter in.

Macbook, Mac OS X (10.5.8)

its an old peavey mixer. I had it it plugged in with a adapter into the input jack. It was working fine, but i accidently raised either the volume to loud or the EQ setting on the mixer to high and got feedback. After this it made a continuos ticking sounds. It's not picking up anything thats plugged anymore because when you do plug something in the ticking comes back.

Will the mac still record from the internal mic without the clicking?

And if you open system preferences > Sound and choose line in with the mixer plugged in do you see clicks in the meter?

And this is just a mixer not a power mixer (PA) right?

its a powered mixer. whenever i plug in something into the input jack it does the clicking. I used to record my guitar like this and it dosent pick up guitar. This was the first time i used the mixer on my laptop, my friend has used the same one in his Mac and its worked fine.

What output from mixer did you try? You may have overloaded the Macs input and damaged the sound card.

NEVER use a speaker out, you may have burned out the input circuitry on the mac.

yeah Im guessing that happened. I still have limited warranty on the mac, but i've heard it might cost as much as getting a new mac.

Thank God I found someone with the same issue, its hilarious because i did the exact same thing with a powered peavey mixer and I blew my sound card too. M question is since the guy above said to NEVER use the speakers out, how Im I supposed to record to my mac through the mixer. And do y'all know how I can get my input fixed so I can continue recording!

Thanks
Pace

since there is no card, you're likely talking about a motherboard replacement, probably $500 at a minimum. it might make more sense to get an (external) audio interface:

without the console in front of me, i don't know, it might be. typically the main outs are used to drive the power amps, so WOULD be line-level, but check your manual to be sure.
