[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

HT1379 A flashing question mark appears when I re/start my MacBook Air 2013. At first, I pressed Power & Option button and it recovered from Internet. Then, four options appeared but none of them are helpful. Could u please help me to solve it asap?

Hello,
A flashing question mark appears when I re/start my MacBook Air 2013. Then, I pressed POWER & OPTOIN buttons and internet options appeared for internet recovery. After internet recovery, the OS X utilities appears with four options (Restore from Time machine, Reinstall OS X, Get help online and Disk utility). But none of them seemed helpful. On the last option Disk utility, the icon created only with 33KB and other disk 1 Mac Os X Base system. On First Aid, the icon Repair disk is disabled. So I could not click on repair disk. Could you please suggest me how to solve this problem asap? Thank you so much for your help in advance!

You can try the following:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Macbook Air 2013

I just got myself a new Macbook Air 2013 and while I realized I couldn't expect the smoothest experience, I never expected this much hassle with it. So many differnet issues. No need to have a sad face about it, though - let's get together and figure out how to make this work! At least we only have one graphics chip to worry about this time around
This is going to be a pretty long post but I figured it's good to have it all in one place. Please correct me if you think this is the wrong way to post these things.
Installing and booting
Booting from a normal 2013.6 USB key works fine, but I couldn't seem to get either GRUB or Syslinux working.
I was able to boot by first installing Arch Linux following the Macbook guide at the wiki (having a separate FAT32 /boot partition). Skip the bootloader installation.
Installing rEFInd from OS X (important!) and installing the EFI stub loader made me able to boot fine.
Separate thread.
Stability problems
This is the big worry for me. Every now and then my system hangs for a brief moment and everything involving net or disk access just hangs there for a while and then it seems to work.
So far it only seems to happen when I run something disk- or CPU-intensive. Also had an occassion when I couldn't start X and just got this repeating all over my screen:
ata1.00: failed command: WRITE FPDMA QUEUED
ata1.00: cmd 61/08:f0:10:8c:c2/00:00:0b:00:00/40 tag 30 ncq 4096 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1.00: status: { DRDY }
On the next attempt it worked fine.
I did SMART short and long tests on my disk and they returned fine:
smartctl -a
There are some messages in my boot that indicate this could be disk and/or ACPI related.
journalctl -b
dmesg
This was on a boot when my NIC was renamed from eth0 to wlp3s0 as noted under Wifi - this should hopefully not be a big deal to fix. Will update when I look more into it.
uname -a:
Linux temperance 3.9.7-1-ARCH #1 SMP PREEMPT Thu Jun 20 22:45:32 CEST 2013 x86_64 GNU/Linux
WiFi
WiFi does not work out of the box. Installing wireless-bcm43142-dkms from AUR made me able to connect to my network. I haven't been able to get it stable yet -interface name changes randomly between wlp3s0 and eth0 between reboots and I get disconnected from my network every 30 minutes or so. Disconnects seem to correlate somewhat with the freezes mentioned above.
Separate thread.
Touchpad
Have only been able to get it to work like a one-button mouse using evdev for now. Looks like an upstream bug.
Separate thread
Audio
In order to get audio, I need to put the following in /etc/asound.conf:
defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1
I'm no ALSA pro, but I can only seem to get output from the headphone jack so far - no speakers yet.

While I'm using Ubuntu and not Arch, I wanted to chip in with my experiences.
First, I am happy to tell you that I've found a fix for the ata errors/freezes (which for me were so bad I could hardly install) -- at least I think it's the same or related. I got udevd spitting errors about blkid timing out, and it couldn't find the disks. I found this in a Ubuntu forum -- sadly, I can't find the url now. Anyway, Pass
libata.force=1:noncq
to the linux kernel parameters (in Ubuntu you can add this to /etc/default/grub). This disables NCQ, which according to that post wasn't needed.
YMMV and I am not certain that it doesn't have bad side effects, but for me it made the laptop usable.
Other findings:
My Fn key, and thus delete, page up/down, media keys etc didn't work. That's because the keyboard has a new device id which isn't in usbhid. I added entries like the existing apple keyboards with the new device id (05ac:0291) and after recompiling, it works. I'm pretty sure this is fixable by passing the correct "quirks" flags to the usbhid module, e.g. "quirks=0x05ac:0x0291:0x00001248", but I'm not sure which flags should be set (I have an ISO keyboard layout which is yet another flag).
My sound card doesn't work. Or; i hear no sound at least ;-). After checking in alsamixer, it had two cards, one HDMI with S/PDIF only and one with analog in/out and digital in. I tried passing "index=1" to snd_hda_intel, which makes alsamixer pick up the right card by default. I'm not sure if the problem is that pulseaudio still has the wrong card, or something else.
My wifi works after installing bcmwl from Saucy (i.e. the upcoming Ubuntu 13.10 release), which was a relief because I feared this not being supported.
Sometimes after resuming from suspend, the screen is totally dark -- barely discernible in bright daylight. First I figured this was an issue with lightum (a daemon which monitors the lighting and adjusts keyboard and screen brightness), but after checking /sys/devices/pci0000\:00/0000\:00\:02.0/backlight/acpi_video0/brightness it turns out that when this happens, only the brightness levels 13, 14, and 15 (which is the brightest) have any brighness at all. 12 and under means no backlight. The only "fix" I've found so far is rebooting, which sucks. I hope this will get fixed (I will report a bug on Launchpad next time it happens).
Somewhere I picked up that passing
i915.i915_enable_rc6=1
to the linux parameters enables some great power saving features in the GPU. From modinfo:
i915_enable_rc6:Enable power-saving render C-state 6. Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6; 2 = enable deep rc6; 4 = enable deepest rc6). For example, 3 would enable rc6 and deep rc6, and 7 would enable everything. default: -1 (use per-chip default) (int)
Oh, and if anybody knows how I get my GNU/Linux partition to show up in the Mac boot screen I would be grateful! Right now I have refit installed, which works but I would rather just use the built-in boot manager, which works on the predecessor (MBA 3,2).

MacBook Air 2013 Camera Problems

I have a MacBook Air 2013 and recently, after the most current update my built-in camera not only does not work with Skype but does not work with Facetime or Photobooth either.
Under "Camera" in System Report my camera does not show up. I have rebooted, shutdown and cold-booted, pressed Shift + Alt + Ctrl + Command when booting.
I don't want to do a fresh install of my (brand new) computer all over again just yet. What should I do? Is it a software issue?
It's rather frustrating because I can't Skype or even Facetime my family and resorting to an external webcam is a ridiculous notion for a laptop.
Thanks,
scintoon

Hey dominic23,
Thanks - that update solved the issue of me not being able to use the webcam. However, now my mic does not work as well. I have rebooted a few times (shut down, cold boot) as well as holding the Shift + Alt + Command when powering up.
Is there a fix to this? Apple seriously needs to fool-proof these updates. Or, at least never have any of these problems in Mavericks
Thanks for all your help.

I tried to register my macbook air 2013 and it said the serial number was already registered

I tried to register my macbook air 2013 and it said the serial number was already registered. I purchased it in my city at an authorized reseller beucase there isn't any Apple Store and they told me that they haven't registered it.
How can I solved this trouble? I want to registrer it.
Thank you very much.

It could be that it was automatically registered when Apple sold it to the reseller (which is what they usually do). It is best to contact Apple and provide your proof of purchase so the machine can be registered in your name.

ISP,INTERNET,SERVER failed on macbook air 2013 13'

hi,i have problem connecting to wi fi with new macbook air 2013 13' 2 days old,network bars showing that im connected all the time,but i cant surf the web,deley btw having and not having connection is about 20-30minutes sometimes is 10 minutes,i tried to reset router several times and its the same,my internet and cable provider is sending 2.4ghz internet,the model of router is
huawei HG532E and i have cable and internet with two devices, router and cable box they are connected each other its a adsl connection.
macbook air comes with mountaine lion 10.8.4 installed i updated to 10.8.5 but i have same problems with both versions of software.
so i run diagnostics and im almost always have first 3 icons green and always (when there is no connection) i have other 3 icons red and failed
ISP
INTERNET
SERVER
and asistent tells me that i need to check my router and access points,all other devices in my home works normaly with the same router.
i know that new macbook air 2103 comes with new 802.11ac Wi-Fi and as far as i know its a 5ghz i read someone have same problem with the same macbook air but different router,and he is assuming that new wi fi AC is not backward compatibile with the older or regular routers,i dont know if this is true but can someone try to help me to solve this problem,maybe i need to change settings in mac?

in the manual i linked up on resent post you can see how to acces the router.
it says
Step 1
Launch a browser on your computer. Enter http://192.168.1.1 in the address box, and press Enter.
Step 2
On the login page, enter your user name and password.
 By default, both the user name and password are user.
 For security reasons or to make the user name and password easy to remember, you can change them. For details, see section 4.1 "Changing the User Name and Password for the Web-Based Configuration Utility".
Step 3
Click Login.
After verification, the web-based configuration utility is displayed.
The first time you log in to the web-based configuration utility, a configuration wizard is displayed. To skip the wizard and further configure your HG532e, click Here when the following message displays: Click Here to enter the advanced configuration page.
and go to advanced configuration page and se WiFi settings, check transfer mode/protocol 802.11 if it is on b/g b/g/n
you can try to set it to 802.11g only and change channel to 11 or 9
Yes you need to do that on your mac when your connected to the network, then you will get an Advance view option over WiFi.

IPhone 4s keeps connecting and disconnecting from my new Macbook Air 2013

Ok I've been having this problem, I recently got an 11 inch Macbook Air 2013 and after I try connecting my iPhone 4s it keeps connecting and disconnecting every 1-2 seconds. I already check the community, I know this subject has been asked many times. Nothing worked out though. My cable cord must be fine because it works perfectly on my PC. I updated the OS and iOS to their latest firmware and still nothing. Whenever I try opening iTunes I get this message saying " iTunes could not connect to this iPhone. This device is no longer connected. " Please if anyone fixed this issue I would appreciate some help. Thanks in advance.

I just solved it, I hope this helps everyone who is experiencing the same problem. Apparently the iPhone seems to charge normally and connect to iTunes if the iPhone battery is over 60%-70%. This must be a power issue the MBA has.

HP 23xi / 25xi compatibility with Macbook Air 2013?

Hi,
I'm looking to buy an external monitor (HP 23xi or 25xi) for my Macbook Air 2013 (10.9.1).
Since the MBA doesn't have a HDMI output, I was wondering if a Mini DisplayPort-to-DVI can be used to connect the external monitor?
I've gone through several forums, and many guys seem to have problems relating to blurry displays on their HP monitors -- when hooked up using DisplayPort-to-HDMI adapters
So, can anyone confirm the compatibility of MBA with the HP monitor, and the adapter used?
Many Thanks
Piyush

Hi Piyush90.
I found information on Apple.com about a "Thunderbolt" connector that enables you to connect your Mac Book Air with other monitors. It doesn't state specifically what monitors it will work with but it looks promising that it will be a viable solution to your question.
I've included a link below to the webpage about Thunderbolt.

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.

1. Follow these instructions, or these for OS X 10.9 or later.
2. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Why can't I update bootcamp software on my Macbook Air 2013?

I'm running windows 8 on my 13" macbook air 2013. Apple sent me a notification of updated bootcamp support software and directions for installation. This web page included a list of the models that are supported by this software and mine is one of them. When I began installing this support software an error message said my computer model isn't supported. I called apple care and they told me it isn't their responsibility to supply windows drivers for people running bootcamp. This sounds fishy and completely wrong. Can someone help, please?

Can you go back and post the web page and actual details (drivers, versions, etc)?
Are you trying to update in Windows and from the Apple Software Update application? manually downloading in Windows? you can use either.
Yes, very fishy. Use to be even worse I think with just how well they are ready to answer and help with Windows on Mac topic.
Use to be the old support pages were to me easy to see and find updates and tech support articles but you can still try there for both your Mac, firmware and model specific, and for Boot Camp.
Also when Mac OS X gets updated, often you download new drivers from within Boot Camp Assistant, too, a 3rd method.
Wasn't clear which method was used.

Help bootcamp windows 8.1 Macbook Air 2013

I have a Macbook Air 2013 running Mavericks and I want to install windows 8.1 on it but first im getting a message saying that the iso is not 64-bit and im so confused because it partitoned my harddrive aswell so how do i get that back.

Not true. In Mac OS's Disk Utility, you can delete the Bootcamp partition then resize the Mac partition larger to use the free space.
Gn12, if your mac keeps trying to boot to your Boot Camp partition, hold down the Option key as you boot so that you can select the Mac partition then use the Startup Disk preferences to select the Mac partition for future boots.
