I have no sound from internal speakers or headphone jack at all.

I recently purchased a used original Macbook Air 2008 model and fixed a few minor issues: Bad Internal Battery (was toasted), new MagSafe Charger & HD's missing Rubber gasket. Also fixed some dents to external casing.

I'm sure that someone else has opened this thing up since 2008 for better or worse. The only other issue I have't been able to iron out is that the speakers and the headphone jack will not output sound.

I've attempted reseting the internal connector of the jack with a pick, checked over all sound settings, clearing PRAM, But no fix.

The computer works great otherwise the USB connector works well the Back lit keyboard works, Screen is great, Everything but the sound works.

My hope is that its not an issue with the sound board. I have ordered a NOS speaker assembly since it wasn't very expensive. I like this laptop and it got it for $110 used so spending a little $$ to repair it is all good with me.

I never could have bought it new. Any Help wold be appreciated.

If both the speaker and the headphone jack are not working that would imply the Audio board needs replacing. Here's the IFIXIT guide: MacBook Air Models A1237 and A1304 Audio Board Replacement You'll need to find out what your exact model is here are there are two versions.

Your other option here is to use a USB sound card but then you'll need to use an external speaker.

Yes have drawn the same conclusion. Iv'e went through All the software issues out there for this. If replacing the Speaker and Sound board don't fix it then its a logic board. Really wish that isn't it. Thanks for all the Help!, Hope this thread helps others in the future.

there are many fixes to this.as it is a faulty one, open up the mac and check the motherboard for any compnents of sorts that appear non functional near to the 3.7mm jack. check continuity for any cracked components. take some acetone(nail polish remover), earbuds and blue tack. use these carefully to remove dirt.if problem persists, desolder the jackand replace it. if even that dosent work, try exposing the connector of the speakers and connect the terminals of a 9v batt to test if it works. if not, go to a reputed apple service shop.

I did check all related components for cracks and cleaned the entire inside when i had the case open, cleaned all connectors with isopropyl alcohol and saw no obvious sigh's of issue. maybe replacing the jack is the answer the problem is that it wont be an easy proposition. The Orignal air has a flipdown door with usb -headphone jack and dvi connector all in one on a custom connector and ribbon cable. thats why this is such a difficult issue to pinpoint inspecting internal components. thank you for the ideas though. im interested about the 9v battery trick to check speaker out put.
