Mountain lion sound
I've upgraded to Mountain Lion and now have no sound! I can see that the 'Mute' box is checked but can't find a way to 'uncheck'. Anyone else found a solution?
I have the same issue here. Since I found the same when I first installed Lion, I am not surprised but still looking for the fix on Lion Mountain. I trust it is a matter of time.

I am trying to get air play mirroring working on my mid 2011 Mac book pro and Apple TV 3 (latest one) with mountain lion. I have the icon, it seems to connect to each other, and the screen shows up on my apple TV, yet it doesnt update, takes a long time to show up at all, just keeps showing the same screen. However, the audio works fine, I tried to play a Xfinity stream through safari, the video didnt show up on apple TV but the sound came through with no delay. Any ideas?
thanks for the help.... even thought it didn't work...
basically I think i either have some virus or this is the result of that stupid update I did... I know i did that keyboard one an itunes one a quicktime one and there might've been another. -
Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

No sound on YouTube since upgrading to Mountain Lion
I think this problem started after upgrading to Mountain Lion, but I didn't notice it for the first few weeks, so I'm not certain. I haven't made any other changes since then. My husband upgraded his iMac at the same time, and he didn't lose the audio on YouTube. The sound is fine for other videos.
Most YouTube content requires the Flash plugin ...
Open System Preferences > Flash Player then select the Advanced tab.
Click: Delete All
Quit then relaunch your browser and try a video.
If that doesn't help, uninstall the old Flash plugin > Troubleshoot Flash Player | Mac OS
Then reinstall new > http://get.adobe.com/flashplayer/
Very important to uninstall the old plugin first.
Then relaunch your browser to test. -
I am using Mountain Lion iOS and trying to connect my MacBook Pro to my plasma TV using AppleTV and AirPlay mirroring. The video does just fine. However, there is no audio coming from the TV. After activating AirPlay I try to select Apple TV as the audio output in System Preferences and it highlights it but then immediately goes back to Internal Speakers and only has sound coming from the MacBook Pro..
What's going wrong ?????
AJAre you sure that WIFI network doesn't have an AppleTV on it? Just because you don't own it doesn't mean there isn't one on that network. The laptop or better said the OS cannot differentiate between an AppleTV that you own or not. If it sees one on the network, it will show you one as being available. The automatic reconnection is happening probably because the last time you streamed to an AppleTV, you didn't drop that connection before sleeping the computer or shutting down iTunes.

How to mute/delete startup sound in Mountain Lion?
Is there a way to shut off/mute the startup sound in Mountain Lion without simply turning down all sounds? For years I have used a third party pref pane called startup sound, but it has not been updated for OS 10.8. Thanks.
1. Login as administrator and open Terminal
2. Create scriptfile for muting
sudo nano /path/to/mute-on.sh
3. Enter this as content, when done press Ctrl+O to save and Ctrl+X to exit:
#!/bin/bash
osascript -e 'set volume with output muted'
4. Create scriptfile for unmuting
sudo nano /path/to/mute-off.sh
5. Enter this as content, when done press Ctrl+O to save and Ctrl+X to exit:
#!/bin/bash
osascript -e 'set volume without output muted'
6. Make both files executable:
sudo chmod u+x /path/to/mute-on.sh
sudo chmod u+x /path/to/mute-off.sh
7. Check if any hooks already exist (these will be overwritten, so make sure it is OK for you)
sudo defaults read com.apple.loginwindow LoginHook
sudo defaults read com.apple.loginwindow LogoutHook
8. Add hooks for muting
sudo defaults write com.apple.loginwindow LogoutHook /path/to/mute-on.sh
sudo defaults write com.apple.loginwindow LoginHook /path/to/mute-off.sh -

Calendar alerts have no sound in Mountain Lion.
When I create apointments in Calendar in Mountain Lion and put (Message with sound) and choose my sound for the allert. When it pops up as a notification it does not make any sound. My notification for the Calendar app is set to (Alerts) not (Banners).
Can anybody help
ThanksAfter trying many methods. I found this a temporary fix. The solution is to set a rule in Mail Preference to run an Applscripts if there is new email. This Applescript will play a notification sound of your choice:
tell application "Mail" to if (count of (every message of inbox whose read status is false)) isgreater than 0 then do shell script "afplay '/Applications/Mail.app/Contents/Resources/New Mail.aiff'"
You can change the path /Application/Mail.app/Contents/Resources/New Mail.aiff to any folder that containt an aiff file. For example: /System/Library/Sounds/Glass.aiff (in this folder you can find all the alert sounds of Mac OS)
Applescript Editor
1. Open Applescript Editor in Applications folder
2. Paste the script in after choosing your notification sound path
3. Save in ~/Library/Application Scripts/com.apple.mail (can name it New Mail in my example)
4. Now you can choose the script in Mail Rules setting
For the Mail rules setting
Open Mail Preferences then Rules then Add Rule. The setting like photo

I have found, in the past few days, since the latest update to Mountain Lion, if the Mac is put to sleep, there is no sound available when it wakes. I have to re-start to get sound back. Is this general??
Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal. -
No sound after Mountain Lion upgrade - is NVRAM reset safe?
Hi there, I've followed a few posts and tried out all of the offered solutions but, as yet, none have worked for me. I'm wondering - is it safe to do a NVRAM reset (I have a 2011 model 24" iMac)? Bit of a newbie, Mac is only 5 months old and was a PC man the rest of my life......
Everything was working fine then I decided to keep up to date and installed Mountain Lion. Now, output is greyed out in 'sound options' (so I cannot select). I'm getting 'startup' and 'notification' bleeps, but no regular sound (eg via programs, web or Spotify).
Sheesh if I had known this I really wouldn't have bothered with the upgrade.... (my first with a new Mac).
Strangely, also, under 'Purchased' in iTunes I still get the option to 'download' ML, although when I try to do so it correctly then informs me that it is already installed. All my other purchases have 'installed' against them.....
Anyway, the main issue I have is with loss of regular sound and any advice/recommendations would be most gratefully received, thanks in advance, Andrew (Scotland).Thanks hpr3, tried that..... but it didn't work.
I notice that under 'sound' in system preferences I no longer have an option to select a device for sound output. Under the 'output' tab, 'Headphones' is associated with 'headphone port' but Soundflower (16ch and 2ch) gives no option for an output device (it has, literally, disappeared!).
Presumably if I can get an output device back, I'll get sound back.
I've read elsewhere that an NVRAM reset may fix if all else fails (but reading on from that there are posts as to what to do if your Mac fails to restart after an NVRAM reset) and I'm naturally a bit anxious as to trying this?? -
No sound after mountain lion update
Just updated to mountain lion from snow leopard...
After the update process was complete (I am currently running 10.8.2 on a MBP 2.3 early 2011 model) I noticed that there was no sound from my macbook pro speakers, except from the startup chimes sound.
In the Sound Settings in system preferencies there is no longer any Internal Speakers option in the output tab. Just a simple Digital Out with the volume slider grayed out.
Same thing with the Audio Midi Setup from Utilities where I am see a Built-In Output but all the sliders are grayed out as well.
If I plug in my headphones then all sounds work. When I unplug them, then the problem continues.
I tried all the following that I read from other users:
Rebooted
PRAM reset
SMC reset
Plug-Unplug the headphones.
Force Quit coreaudiod using the Activity Monitor Utility
Nothing has worked.
Any help will be appreciated.
NasHi there.
Sorry about my late reply but my issue was solved unexpectedly... I plugged in again the headphones and I forgot to plug them out for 20-30 min... Then when I unplugged them the problem was solved!!!! Therefor I didn't have the chance to try your solution but I'll keep it in mind for next time.
(However I was also experiencing some other issues as well after the upgrade so I erased everything and installed from scratch. Hope it never happens again.) -
I have mac book pro and recently bought mountain lion online, i then used bootcamp to upload windows 7 now i have no sound when i use windows what can i do to get sound.
Install the required Windows drivers: Boot Camp Support Software 5.0.5033. Download this link preferably from Windows. Otherwise, download onto a FAT formatted USB disk from which you can copy to your Windows system.

No sound after mountain lion upgrade
After I upgraded to mountain lion, I'm unable to get sound from the built in Macbook speakers. The headphone jack works fine, any advice?
I have the same problem: Almost a year later. Like you, I tried all the suggestions given in these forums. Nothing has worked. Is it possible that there is still not a solution after all this time?
Does Apple have a fix yet?
Do any users have a fix? -

Does anyone have any thoughts on what might be causing this? Anyone else seen problems with sound files?This is how it looks like for me. This accours on every Boot Up.
