Fundamental Sound Play Issue- Help Requested

Hello to all,
First thanks for taking the time to read and hopefully reply to this question. Simple one. Just purchased an audio-technica AT-LP2D USB turntable, and installed audacity. I am running Macbook Leopard operating system and have 2 small speakers/subwoofer that connect into my headphone jack on the Macbook. Here are my settings:

Sound settings: Output: Built-In Output
Input: USB Audio Codec

Audio Devices: Properties for: Built-in Input
Default Input: Built-in Input
Default Output: Built-in Output
System output: Built-in Output

Audacity Preferences:
Playback Device: Built-In Output

Recording
Device: Built-in Input
Channels: 2(stereo)

I have the turntable working fine and hooked up just no sound on the speakers. I apologize in advance if this is a bit of a basic (or obvious) question; I don't even want to record my LP's to digital just want to listen to them and eventually work with garageband. Thanks again for your input.

That's what Playthrough is supposed to do.

Audacity Preferences > Audio I/O > bottom two clickies.

Mac OS-X sees running the record and playback at the same time as an unstable condition, so I wouldn't be shocked if it didn't work--or didn't work like you want it to.

Ok,
Tried with your suggestions and still nothing. Cannot get any output from the Mac with the computers speakers even though they are powered. So if I want to listen to this record player, or a record player in general, what software/turntable do I need? I would be fine running things through GarageBand if that was possible as well. Thanks for the help again.

I was going to send you to the OS-X System Preferences panel, but I see you've already been there.

Unless you know this is possible--that you've seen it done before, I'm going with you can't do that at all. It was a conscious design decision on Apple's part to make it really difficult to run the input services and output services at the same time. There is an extraordinarily tricky programming package that is necessary to make a Mac do telephone calls on the internet, which, of course, requires a microphone and headphone to run at once.

I know it's possible to use iChatAV and talk to somebody with the built-in microphone and hear with the speakers, I have personally done that, but that's one in a row.

Before you explode with righteous indignation, let me point you to the Windows people who regularly create terrible damage, feedback, overload, clipping, echoes, muffling, stuttering, and various other damage modes by having an infinite variety of audio pathways--including listening to the speakers while monitoring an audio device--a radio in my case. Microsoft has recognized what chaos this causes and has greatly restricted the sound pathways you can choose, thus making them a good deal more Mac-like.

This is where someone else jumps in and calls me all wet and reveals how to do this, but I sure doubt it.

Some "Ghetto Blasters" have AUX inputs in the back and you can connect any line level item and listen to it through the speakers.
