Loss of audio in macbook air

I keep losing audio on my macbook air and it does not come back until I have restarted. Is there a way to avoid having to restart?

Do not sleep your Air (close the monitor with headphones attached) with headphones attached, this is known to affect some Air under Mavericks.
I presume you are using headphones? * this occurrence is being looked into.
Much testing on my own and others as well show that in some instances this occurs in Mavericks.
If you choose you may contact Apple for an appt and diagnostics.
However as said, refrain from having phones attached when you close the monitor to prevent this until it is resolved
peace

How can i stream video and audio from macbook air to my tv?

how can i stream video and audio from macbook air to my tv?

Wirelessly: you need an AirPlay - enabled device such as an AppleTV.
Wired: if your TV has an HDMI port, you need a Thunderbolt to HDMI adapter such as this one:
Mini DisplayPort to HDMI® Adapter w/ Audio Support
If your TV does not have an HDMI port you will need a converter that will convert HDMI input to whatever input your TV requires.

[SOLVED] No Audio on Macbook air 2013

Hey all,
Currently I have no sound (either through speakers or headphone jack) on my macbook air 2013.
Card: HDA intel audio controller
Chip: Cirrus logic CS4208
when I boot up alsamixer, it says everything is unmuted and everything is at 100% volume, everything looks like its working fine but still no sound.
Things that I have already done but no effect:
blacklisted snd_intel8x0m (as per ALSA page)
added options snd-hda-intel model=intel-mac-auto to both my sound.conf and modprobe.conf files.
I am running the most up to date version of everything, including kernel version 3.12.8 which is supposed to have out of the box support for the card.
Let me know if you need any other information!
Thanks!

I pretty sure its not that. I use ratpoison as a WM (I like a minimal arrangement for my laptop) which doesn't use pulseaudio. Even when I had Gnome with pulseaudio. I still had the same issue.
So I ran speaker-test -c 2 on my computer and this is the output:
>>> speaker-test -c 2
speaker-test 1.0.27.2
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory
Which file/directory do I not have?
I have also checked amixer and none of the channels are set to 'off

Capturing streaming audio on Macbook Air?

I want to capture streaming audio from a website on my MacBook Air. But is this possible when the MBA lacks an external microphone? How do I go about it? The sound quality needs to be decent. My compture is brand new and has OS X10.9.1 if that's relevant. Many thanks!

There are tons of such audio (and video) capture apps on the APP STORE, such as twisted wave, sound studio, Amadeus,etc etc
more professional and pricey APPS such as Adobe tools, screen flow, capture screen.
most of the cheap ones can be had for $5 or so.
Why do you need a Mic? audio can be captured internally. Your Air does have an onboard external mic on the left side, either 2 holes, or older Air one larger multi-hole mic input.
for web audio however you want to use an application.

How do you get 24/96 audio from macbook air?

How do you get 24/96 audio out from macbook air?

If your media source is limited to a DVD disk, then a DVD reader will somehow have to be employed to read that disk. Apple sells a Superdrive specifically designed for use with the MBA, but I've found that many others will work almost equally as well.
Some DVD disks already contain a digital file suitable for play, when directly copied off the disk. However, for more traditional DVD movies, it will require an application to perform what is called "ripping", to convert and copy the DVD's contents to a file that can be moved and played off the disk. I have used an application called "Handbrake" with reasonable success.
After ripping, you may need another application to convert it to a format specific to the media player you may choose to eventually use. e.g. to convert into a file that iTunes may import.

Macbook Air Mid 2013 No Built-In Audio

Hey everyone,
I have an issue with my friends Macbook Air (Mid 2013 Model). After listening to some music through his speakers, he unplugged his Aux cable and then plugged them back in to find that he didnt have built in output or input anymore. I have tried all of the following to fix it:
Reinstall OS X 10.8
Run all of the Automation tools found in the application Onyx
Reinstall certain .kext files (AppleHDA and AudioAUUC)
Repair permissions
Re-seat the speakers in the device itself
Reset coreaudio
Resetting SMC, PRAM, and NVRAM
Clear and re-build kernal cache
Cleaned the headphone jack
Plugged in an audio interface
Reloaded from Time Machine Backup
etc...
I've literally tried almost everything in the book. The only other thing i can think of is installing a copy of Mavericks when it comes out (In October i believe). There is no boot up chime, and after running the OS in verbose mode, i can see that AudioAUUC.kext is not being loaded. Built in audio does not appear is system profiler. What can i do to fix this problem? Could it really be a hardware issue? If so, what can i do to fix it?

Test after each step.
1. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
    Option click the speaker icon, if present and select Internal Speakers.
2. Plug in the head phone and reset SMC.

Audio too loud on my MacBook Air!

So, I just purchased my MacBook Air from Best Buy (as an Open Item since there was an awesome markdown plus coupon markdown on top of that, and 18 months financing is pretty cool too). My problem is that the sound is extremely loud on this system, especially when I have headphones plugged in. I have the master volume at the 4-5 level (out of 16, mind you), and headphones can only be set on 1 (or if using the gradual shift with Shift+Option+Vol Up/Down it would be more like .5). If I have it set to full volume, the speakers are blaring (and I'm sure I'd be permanently deaf if I tried that with headphones on). This is my first Apple laptop, and I don't have this issue with my iMac (but I've got a pretty decent set of external speakers hooked up to that, so if there is an issue I don't notice it).
I tried fiddling with the sound in the System Preferences, but all I have access to is the Alert Volume slider and the Output Volume slider (which I found is the same as using the volume hot keys). And for the Output preferences tab, I can select the headphones, but all it gives me is a balance slider, no individual volume control for them.
I've been googling and searching this issue in this Support Forum, but most of what I'm finding is about the system having the opposite problem (extremely low audio), and the few that seem to have the same problem as I do aren't really getting a definitive answer. I thought I saw one where somebody had this problem and took it into an Apple store, where they popped the laptop open and noticed that something wasn't hooked up correctly (wires hooked up wrong, or something like that). But I can't find that particular thread anymore, so I'm a bit uncertain on that - anybody know where that thread is and can I have a link?
I'm wondering if this particular MacBook Air was returned because of this sound issue. Should I take my MacBook Air in to get it looked at? And if so, should I just go into a full Apple store rather than the Geek Squad (which is more PC oriented)? I did purchase a Geek Squad Black Tie plan, mostly for the accidental coverage. (I'm a klutz).

I think I might have figured out why the volume is bothering me.
On my iMac, I have a decent set of Creative external speakers hooked up and it has an external volume/bass controler w/ headphone jack. I've set up the volume on the speakers to a comfortable level, and use the iMac internal sound control to do minor editing - which is normally set around 11 out of the 16 "notches" and that way I can increase/decrease w/o fiddling with my Creative volume control.
But when I unplug those speakers out of my iMac, I end up with the insane volume that I'm not used to (I jumped when the sound played and had to mute it. XD I think I should start video logging my troubleshooting for the lulz.) I also figured out that the system remembers the sound levels when you plug/unplug headphones/external speakers. Very handy. :3
So, I'm just used to having a fine tuned control over my sound, and when I started playing on my MBAir, I thought something was wrong. I'm probably just going to go get myself a really good set of headphones that have a volume control on them so I can get the same results I get from my iMac.
Thanks for the help! <3 I'll let y'all know if I run into anymore problems!

With newer MacBook Air, sending both video and audio to an LG TV works fine, but I want to send the audio to a sound bar attached to the TV. Any way to do this?

I am trying to get audio to play through the soundbar attached to the TV for great sound. Works fine with Apple TV, but on the MacBook Air, system preferences will only find the TV speakers. If I change the settings on the TV to external speakers (the soundbar), then I get no sound at all. The HDMI connection does what it is supposed to do, providing video and audio, but the audio can only go to the TV. I don't know if you can go backward and send only video through HDMI and then connect to the soundbar through the mini jack ports on the computer and the soundbar. Any solutions will be appreciated.

its important to do this in the correct order so the camera will be senced by the Mac and to prevent the Firewire connection from electrical damage:
power down your Mac
connect firewire from camera to Mac
power on camera and insert tape in camera and play back
power up Mac
start QuickTime
File > Preferences > record tab
video source - select the camera you have
sound source - select the camera you have
quality - select device native
the video should show in the QuicTime window
a green line below video will show presence of sound-it will play through the speakers if they are selected in system prefernces
rewind tape and playback
click on red button to start recording

MacBook Air to TV via HDMI...No Audio?

How to get audio on tv when Macbook Air is directly connected via MiniDisplay adapter to HDMI /TV.....? Only have video at this point??

Are you using this particular dongle? I've had trouble with some of these OEM adapters in the past. However, you can't beat the pricing if it works (I think the Apple version is $29).

WIFI Packet Loss/Jitter MacBook Air 11 & LION OSX 10.7.1

I started using computers more than 30 years ago when I was 5, I had my first IBM PC at the age of 10 and have never had any interest in paying over the odds for an Apple mac mainly because I saw the Mac as a kind of "Can't open nothing", one mouse buttoned retard of the computer world.
That is, until now.
I set up an online business 3 years ago and rented a dedicated server and set the whole business up in a cloud, so to speak. Having done that, all I needed a laptop for was a remote desktop connection and to run a SIP phone (Internet phone).
My PC based laptops had almost nothing installed on them, and I wasn't using software on the laptop itself, I was using remote desktop, so - why not try a MAC? The new Macbook Air 11 is small, light and made of metal and glass so should be robust enough to travel with me.
I have to say, this was the worst move I've ever made.
I opened the new shiny macbook and the first thing I noticed was that the internet seemed hit and miss. Moving around the room I managed to find a spot whereby pages woud load quickly. Strange, my £200 acer laptop was sh.t fast everywhere in the house. No matter, I packed it back away and carried on working on the Windows machine.
I've come to Newquay this week, and i've started to try and use the Macbook again in a hotel. The wireless signal in the room is low, and speedtest shows about 1 meg down and 3/4 meg up. That may sound bad to you, but remote desktop uses about 5k/sec (modem dial up speed) and the softphone, well, my Asterisk VOIP setup is confugured to use the GSM codec so that's 8k/sec each way + overheads.
This whole setup was deliberately designed to be "thin" so I can travel with ease and work on bad connections like USB internet sticks.
Anyhow, the Macbook was unable to hold a stable connection to the remote desktop or SIP phone, even though the speed test showed a whopping 1 meg up and down. What you may not be aware of is that there is more to a connection than the speed, there is the quality as well. How many packets are lost / how much "jitter" is on the line.
Anyhow, we're not living in the 3rd world, I ran a PINGTEST and it showed a small amount of jitter but told me the line was class B, online games may suffer but voip should be fine.
I unpacked the Acer, placed it in exactly the same spot as the Apple had sat in and it worked beautifully with 1 bar of wireless signal, all day long. Phone calls were clear.
So you know now what I'm thinking. I'm sitting here with my £200 acer because I can't use the £1500 macbook air 11. I paid nearly sixteen hundred pounds for this piece of .... and it doesn't ...... work. Time to contact Apple support.
2nd Mistake!
Representitive 1: - Told me that I can't compare the Macbook Air to the Acer, the Acer has Google Chrome and everybody knows Google Chrome is the fastest browser. I was told there was nothing more he could do, its probably a bad line at the hotel. When I explained the Acer works fine for voip I was told well, maybe it is getting a better signal. I explained the Acer has the cheapest possible parts inside it and paid 1500 for this macbook, expecting it to have quality parts inside and was told I'd paid for the size, because its so small but its not considered "powerful". Apple do you train your staff? Clearly not.
Thank god I wasn't paying to talk to this moron.
Representitive 2: - Had no idea what packet loss or Jitter was, got me to do a speedtest and said that looks fine. Then he got me to remove the WIFI adapter and re add it in the network settings.
Guess what, nothing changed, its still the same hardware and software.
Representitive 3: - Still not really understanding "quality" issues with the networking interface, I was asked to install the latest Java client. I did it, only because I wanted to comply with Apples wishes so they'd help me, but they weren't helping and Java has nothing to do with the network adapter, so that was useless advice too.
Apple seem to have no idea there is a problem, even though Google has pages and pages of people saying the same as me, and their own discussion forums have thousands of people complaining https://discussions.apple.com/thread/2664670?start=0&tstart=0
Finally, late yesterday whilst speaking to d.ck head number 3 at Apple support, we found a forum post talking about a fix, 10.7.1 update. I told d. head number 3 about the update and he suggested I applied it. So I did and everything looked great, for a whole evening.
This morning, I switched on again and the same thing, slow remote desktop, choppy unusable phone. Remember the phone needs less than 20k for a conversation, thats 0.2 meg. Speedtest again showing a whole meg both ways.
I called apple support again, this time being a little forceful, and I've asked for this to be escalated, but the bottom line is - they have no fix, they don't aknowledge this as a problem and I was told LION is new, so maybe it's got a bug..
I told the guy on the phone this is a network driver issue, the intermittency of the problem shows that and the Apple's lack of settings for the network adapter means the unit is autonegotiating with the router and choosing speed and duplex settings on its own. Sometimes it does that correctly, other times not and the connection although fast has a lot of noise / packet loss / corruption.
I've found a workaround, you put the unit to sleep and wake it up again and it runs fast until the next shutdown. Not really acceptable seeing as I was paying for "the cream of the crop".
I will definately not be recommending Apple products, and i'll certainly not be replacing the Windows laptops in my business with Apple's toytown system- i'd go out of business if I had to rely on this.
All there is left now, is to look at Boot camp and see if I can wipe this waste of space linux hack from the unit and install Windows 7.

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)?

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)? I often miss the visual power percentage in the top bar, so would like an audio alert as well.

For global alerts, yes:
There is no need to do anything before the alert appears, and the MBA will not lose data should it go to sleep. If it goes to sleep at 0% you still have several hours to plug it in before it shuts down.
I wouldn't even bother displaying the percentage value.

Macbook Air no longer recognizes external audio devices

My Macbook air's audio port recently stopped recognizing external devices such as speakers and headphones.
The external devices are functional with other devices and fully plugged in, but only the internal speakers will produce sound.
This problem happened just recently with audio devices that had been working fine with the laptop before. I did not use any
audio devices that I haven't used with the computer before. They are fully plugged in, and I've already tried twisting the head
of the cord to see if it's going bad. The headphones I tried to use work fine with my iPhone.
I've tried opening System Preferences > Sound, to select the device, but it doesn't show up in the device list.
The internal speakers work fine, and continue to work even though the headphones or external speakers are plugged in, and in
the case of the external speakers, turned on.
Does anyone know if updating my audio driver would help?
Has anyone expirienced and resolved this problem or a similar problem?
Does anyone know how I can actually get in touch with someone who works at apple without having to go in to their store, as
I don't have time to do that and wouldn't be able to leave my laptop for repair since I use it for college?
Any help would be greatly appreciated!
Thanks so much!
Update:
I've tried using "Audio MIDI Setup", the external devices do not seem to be recognized by the computer.

Because something has gone wrong. I have no way of knowing what, and without backups, you're in a very bad situation.
If you want to preserve the data on the startup drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Start up from the Recovery partition, from Internet Recovery, or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
2. If Method 1 fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
3. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
4. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Can't get sound on My MacBook Air, Shows No Audio Device. How do I fix this?

I have a MacBook Air that I receved from a relative, it is beyond it's warantee period.
Today, while on my MacBook Air, the sound suddenly stopped
I went into System Preferences, and when I click on Audio, it shows the sound as muted, but doesn't allow me to unmute the sound
When I went into System Profiler, it is showing under Audio (Built-in): Intel High Definition Audio: Audio ID - 0
no Audio Device
How do I fix this and hear My sounds again?
Thank you in advance

i got same problem too but it's 2011 macbook pro 10.6.8 also SD card out of order as well and it's horrible computer I ever have. no more mac

After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolutio

After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolution from the community, but hope to get the attention of Apple engineers. If you are having same problems or have a miracle cure I am all ears.

May start my own thread, but I'm having similar issues.
I've been using an old iMac (running 10.7.5) and Apple TV for years with no issues. Last week I bought a new Macbook Pro running Yosemite and have had audio issues multiple times. The weird thing is that sometimes it works flawlessly, other times (like now) I spend half an hour just trying to get a song to play.
My issues are: When I got to "computers" in Apple TV to stream my music, my music is sometimes chopper or intermittent, and I seen to know when it's going to happen based on the status wheel just before it plays. When I choose a song, the status wheel will spin for an unusually long time, usually an indicator that the audio is either not going to work, or stutter.
When it does finally pull up a song, the playhead sits at the beginning of the song for a good 3-5 seconds before actually playing. Then, when it starts playing, it's all downhill. It will play a few seconds, drop out, play a few more seconds, drop out, and then ultimately the playhead will keep moving across the song as if it's playing, but there's no audio.
Again, this is a new phenomenon never experienced by me. I've tried everything I could think of, some of them all at once:
• restart Apple TV
• restart Macbook Pro
• quite iTunes/open
• turn off Home Sharing on iTunes then reconnect it
• unplugging and cycling both my modem and router
None of these have alleviated the problem.
The odd thing is, like this morning, the audio started up perfectly and never gave me any issues. It wasn't until later in the day that it started. Perhaps after the macbook pro had been put to sleep? Not sure.
Regardless, this is an annoying trait, one that's new to me and my system (as stated, worked flawlessly until my new purchase), and is 100% limited to either a) the macbook pro b) Yosemite or c) both of them.
