1 A1237/A1304 Audio Board Differences
I recently upgraded my A1237 to a A1304 logic board. Everything works fine except for audio. The audio board *is* detected and shows up in the control panel, however no sound output can be heard. I know that one of the speakers is attached directly to the audio board and I've checked all the connections.
In the System Profiler
Device ID: 0x10DECB79
Audio ID: 53
Available Devices:
Headphone:
Connection: 1/8 Inch Jack
Speaker:
Connection: Internal
If someone could compare this info to their true A1304 (Not a frankenstein version like mine) Or someone has also done this swap. I'd greatly appreciate any info.
Esta é uma boa pergunta?

So the original machine was the A1237 (Early 2008 Orig Macbook Air 1,1) and the logicboard swapped in is from a A1304 (Late 2008 Nvidia Macbook Air 2,1) I do not get audio out of the external port either. I'm not sure where I should be looking for a 'red light'. Would this be inside the headphone jack itself (in the IO hatch)? I don't see one on.
