So they replaced two things: Audio Board (Part No.922-8379), and Audio Board Flex Cable (Part No.922-8380). So I took it to the local Apple service center here in Manila and they did determine it was a hardware problem: the audio board and the flex cable were screwed. I tried everything you guys did, to no avail. And it's becoming a widespread thing, from the looks of it. I think, but am not 100% certain, that I updated iTunes after the problem first appeared. The machine gives the blue screen and either locks up, or freshly reboots to the Login Screen (with previously logged in users now logged out, ie a restart). I have also had system crashes when trying to wake from sleep. I have since removed it using its Remove option in one of the menus.

The only software I've installed around the same time this problem first occurred was CoolIris. The Sound Preference panel says 'No Input Devices Found' and 'No Output Devices Found', and the volume slider is grayed out, set a max, with a grayed Mute box ticked.ДЇlash video on various sites plays only for a second or two before stopping, although the file continues to load in. Pressing the volume buttons on the keyboard flashes up the level indicator on the screen but it does not change, and also a little 'O' with a line through it appears underneath. Best of luck.ДЇrom about 2 October my MacBook Air developed the same problems as described above: no sound output and (flash) video playback issues. HTD says: Let me know if this did or did not work for you. Remember, if you just keep digging around, you will eventually find a solution.

If you have a MacBook Air, you might want to check out for an Audio Cable replacement and install which you can potentially do yourself (but only for those who know what they are doing please!). If it still doesnвЂ™t work, you can take it the Apple Store to get fixed.

#Why does my laptop say no audio output device installed portable

I saw plenty of threads on the Apple Discussion forums around this issue and it seems to happen to any type of portable Mac. I would love to find out what solution worked for you or if none of them worked.

I DONвЂ™T recommend sticking anything else into that headphone jack though (grin!). This was another case of the Mac just needing to be prodded by something to get it going. I just took some headphones from my iPhone and plugged it into the headphone jack and magically the on-board audio output started working (it might have worked had I tried the USB headset fix above вЂ“ but I couldnвЂ™t find one). Plug in standard headphones вЂ“ the funny thing is, the fastest and easiest fix is the one that actually worked for me. (Give it a reboot as well just to be sure it вЂњsticksвЂќ). If you do, thatвЂ™s great! Then try unplugging the USB device and see if your on-board audio output device starts working. If you have a USB headset or speaker, plug that in and see if you get audio output through that device. Plug in a USB headset вЂ“ sometimes your Mac simply gets confused and needs to be literally poked by another audio output device. Go this preference file (location shown below) and just delete it and reboot. But it also seems to be the source of all sorts of odd issues that you can never figure out, and tends to get corrupted. It controls those on-screen images that you see when you change the volume, eject DVDs/CDs, change brightness, etc. If it does work, there may be some other type of conflict going on and I would continue with the tips below.Дelete the BezelServices preferences file вЂ“ this is a mysteriously magical file. Check to see if the audio is working after that. Start in Safe Mode вЂ“ try booting in вЂњSafe ModeвЂќ by holding down the Shift key when starting up. And be sure to Repair Permissions after installing the combo update.

Go to the Apple site and download the latest Combo Update for your version of OS X. Reinstall the latest OS X Software Update вЂ“ this is a great fix for all sorts of issues as well. Repairing permissions via the Disk Utility is something that is easy to do but can take a little bit of time. Repair Permissions вЂ“ this is a good thing to do regularly anyway, especially before and after you install new system software updates. Sometimes your computer simply gets confused. Reboot вЂ“ rebooting your computer is a tried and true method for вЂњfixingвЂќ all sorts of problems (and it is not limited to just Macs, it works for PCs too!).

How to fix the вЂњNo Output Devices foundвЂќ issue on your Mac: Here are all of the known steps to recover your audio. Since deleting bezel services the issue has not returned for six months. We previously replaced the audio cable and then the problem came back.

I was able to correct the problem on my daughter's MacAir by deleting the preference 'bezel services'. This issue seems to plague the MacAir and no one seems to have the best answer.
