Streamed audio stuttering since update to Yosemite

I have a big problem with stuttering streamed audio and video (Spotify, Deezer, Netflix etc) since I updated to Yosemite. It seems to get much worse when the stream in question is not the "active" thing on my screen. For example when the screen goes black due to standby mode when listening to Spotify or when surfing on one tab while listening on Deezer on another. Also, while watching Netflix on another screen with the laptop lid closed, it doesn't take long before the audio and video becomes off sync. Does anyone else have this problem or have any idea on a solution?


I have a Macbook air 13" mid 2012 and 100 mbit connection. I completely erased the hard drive before installing OS X Yosemite.

MacBook Air (13-inch Mid 2012), OS X Yosemite (10.10)

When you have the problem, note the exact time: hour, minute, second.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console 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 Console in the icon grid.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES All Messages

from the log list on the left. If you don't see that list, select

View Show Log List

from the menu bar at the top of the screen.

Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.

Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.

Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

Thanks for the reply. I tried to be selective in copying these lines, but since I didn't exactly know what I was looking for I might have posted too much or accidentally left something important out. Pardon for that.

Please read this whole message before doing anything.

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.

The purpose of this test is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

Test while logged in as Guest. Same problem?

After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

*Note: If you’ve activated “Find My Mac” or FileVault in OS X 10.7 or later, then you can’t enable the Guest account. The "Guest User" login created by "Find My Mac" is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.

Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.

2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.

You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.

In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.

You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.

Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.

4. Here's a summary of what you need to do, if you choose to proceed:

☞ Copy a line of text in this window to the Clipboard.

☞ Paste into the window of another application.

☞ Wait for the test to run. It usually takes a few minutes.

☞ Paste the results, which will have been copied automatically, back into a reply on this page.

The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.

5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.

6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.

7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.

8. Launch the built-in 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.

Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.

9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter

exec bash

and press return. Then paste the script again.

10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.

If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.

11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line

[Process completed]

to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.

12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.

At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.

If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.

13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.

14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

A.

Disconnect the "Music Streamer" device and see whether there's an improvement.

B.

"CleanMyMac" is a scam and a common cause of instability and poor performance. The developer's instructions don't completely remove it. Follow those instructions, then do as below.

Back up all data before proceeding.

Triple-click anywhere in the line below on this page to select it:

/Library/LaunchDaemons/com.macpaw.CleanMyMac2.Agent.plist

Right-click or control-click the highlighted line and select

Services Reveal in Finder (or just Reveal)

from the contextual menu.* A folder may open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Repeat with this line:

/Library/PrivilegedHelperTools/com.macpaw.CleanMyMac2.Agent

Restart the computer and empty the Trash. Depending on the version of the product that was installed and how it was removed, you may also have to remove these items in the same way:

~/Library/LaunchAgents/com.macpaw.CleanMyMac.helperTool.plist ~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist

Never again install "CleanMyMac" or anything like it.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Once again thank you. The Music Streamer is my DAC, didn't make any difference wether it was connected or not. And I couldn't find any of the Clean My Mac files you mentioned. I had all ready deleted a few days ago Clean My Mac with AppCleaner though. Could it still be any traces left of Clean My Mac on my Macbook since you found it in these logs? Also, is AppCleaner something that I shouldn't use either?


Anywho, I did find a solution for Spotify at least, haven't found anything for the audio and video getting out of sync yet. I tried preventing spotify from "App Nap"-ing through the "Get Info"-tab, and so far I haven't been able to reproduce the stutterings on spotify...

Nov 12, 2014 9:22 AM in response to Linc Davis

Hello: I too am having audio stuttering problems. I will reread your posts above carefully....


Here's what I noticed to date:


I now have "stuttering audio" --across all browsers (Safari, Opera, Chrome).. Even iTunes is stuttering


I am running Yosemite 10.10


-- looking at Activity Monitor I noticed that com.apple.geod process was hanging... I forced quit it and I am still have problems


I saved a sample here


https://www.dropbox.com/s/g6o2rb6o59k82k9/FrankMcP_Sample%20of%20com.apple.geod. txt?dl=0

Mar 20, 2015 11:34 AM in response to frankmcpartland

My problem was App Nap, introduced in Mavericks, it puts background apps to sleep. I disabled it from the Get Info menu once, but after the latest update to Yosemite the stuttering came back and the option is gone. I used the global disable App Nap option with the terminal described here:

http://www.maclife.com/article/howtos/easy_mac_hacks_disable_app_nap

Streamed audio stuttering since update to Yosemite
