MacBook Air no audio output device found ???????? please help

Dear all,

since yesterday my Mac Book Air can not find audio output device anymore, so no sound.

Its actually strange because i was running the Hardware Test (Boot + D and so on) but it does not show any failure or problem.

Could you please help me? Anybody has any idea?

Thank you
Carsten

I have a similar issue, (1) I have no sound from either my internal speaker or from headphones, (2) the volume control does not appear in the menu bar, (3) opening garage band brings up an error code "Core Audio: Selected Driver not found. (-10202)", (4) in iTunes I cannot play songs (the tiny speaker icon to the left of on the song shows volume but the timeline at top does not advance), (5) same youtube issue (appears to start but stops after a second or two), (6) some other video (for example ABC full episode player) will play but no audio.

I tried (1) cold boot, (2) zapping the nvram, (3) reinstalling quickplayer, no change. The other threads are for other hardware and refer to a headphone jack reset issue, but that seems to involve different hardware (there is no "red indicator light" on the mba).

This problem appeared out of nowwhere, it happened after (but not immediately after and apparently not associated with) installing itunes 8.0.1.

any help would be greatly appreciated...

Macbook Air mid 2013 (My beloved)

Lost all sound about 6 months ago. Tried all the methods mentioned on previous 24 pages, all no no avail, with no installed audio hardware reported, it appeared to be a logic board problem.

Bluetooth speakers worked OK but sometimes a bit scratchy to the Speakers. BT headphones from my phone did not connect. HDMI to TV via Thunderbolt adaptor also worked with 5m cable across the floor to the TV.

Put up with this for 6 months, not worth $600-odd to repair with no real warranty of enduring success.

So just a week before Xmas I bought myself a Lenovo laptop that looks a lot like the new gold macbook. Thin/skinny, 2 C - ports plus 1 USB3 as light as the air, same size, converts to a tablet. Decided I had to learn Windows instead. Still have a house full of macs to replace as they fade.

BUT YESTERDAY A BIG NEW SYSTEM UPDATE INSTALLED (=10.12.2 (16C67), and audio is 100% normal now. Now I have 2 small similar competing laptops, and will have to carry on as planned, and learn Windows instead. Cannot depend on the macbook series any more after 6 months of no sound, so will probably retire all the macs as they fall over with time. Will be a sad but inevitable day sometime in the future.

So advice for now is get the OS update 10.12.2 (16C67) before you decide to replace the old Macbook.

Thank you, marcopolo! Deleting bezelservices did it for me. I never would have found this on my own! 😮😀

Use software like OnyX, and delete Audio Cache and restart the mac.

Hi, did anyone try to buy an external sound card (USB), to solve the issue?
