Is My Pb Broken? Options

[joshuas]

Hello,

This is my first time here, I found this site while searchng for music on mac help.

I need and would really appreciate if someone could help me out with this problem:

I have a 15-inch, G4 aluminum Powerbook. It has a line in port on the side. I decided to try recording some guitar using Garage Band. So I did the following:

1. Plugged my electric guitar into an amplifier.

2. Took another cable, and pluged that into the headphone port on the amplifier, which I then plugged into the line in port on the PowerBook using a 1/4-1/8 adapter.

3. I lastly plugged headphones in the Powerbooks headphone port so I could hear what I was doing.

In Garage Band everything seemed to work, I was playing around with the guitar effects and evertything seemed to work fine. The green to yellow to red monitor thing was showing that sound was coming in.

My problem is suddenly it stopped and it doesn't work. I cannot get anything to play and the monitor thing shows no sound coming in.

So....My question is....did I break something? Was I not supposed to do this? I am new at this music recording thing and don't know what to do. So if anyone can tell me if I broke my powerbook I would appreciate it.

Thanks so much for your time in reading this whole post.

Hi again,

Thanks very much both of you for the replies.

I tried checking every part, using a different amp, different cables, etc.

Finnaly I used a different cable with a CD player instead and the powerbook picked it up. So thankfully my PB seems ok. I think the problem is the adapter I have, perhaps that is not working or something.

I just have one question...should I be doing what I was doing? ncastel, do you think it is better to use an external sound device like the Griffin iMic?

Thanks again for the time, I really appreciate it.
