I just downloaded Yosemite to my MacBook Pro 15" retina laptop. And it seems to be just fine, until I try to run graphics or video. I begin to get random popping sound from the right speaker of the laptop. It is quite bad when you start World of Warcraft but also is present when Safari loads up web video or audio. It seems to be around 1-4 Hz in frequency. It is pretty annoying. Any ideas on what that might be from?
In the terminal, type that:
sudo killall coreaudiod
And in the sound preferences, make sure your internal speakers (and not HDMI or other device) is selected.
This should resolve the issue, did it for me.

There’s more to the conversation
Read all repliesI've been having a similar issue too on my late 2011 Macbook Pro. Mine just cuts out and then back in.
Hi bugsortega,
Welcome to the Apple Support Community!
I understand that random sound issues can be frustrating. One thing I would suggest in this situation would be resetting the computer’s PRAM. Please use the attached article for information on resetting the computer’s PRAM. The article is for OS X Mavericks, but he steps are the same for OS X Yosemite.
OS X Mavericks: Reset your computer’s PRAM
Cheers,
Joe
@bugsortega just curious, are you using any third-party music software like protools, reason, etc?
I've been having weird sound issues, and resolved some of it by uninstalling them for the time being. unfortunately i don't think the drivers for them are compatible yet with yosemite and it caused some weird issues on my system.
No third party music drivers that I know of. I have the new Yosemite version of iTunes loaded but don't use it that much. I notice that the staticky scratchy sounding output comes only with Safari and video online. Not sure if it is a Flash plug in issue, or what. It seems to be worse when logged into and playing World of Warcraft. So I don't know enough about it to even hazard a guess. Just know that it is really, really, annoying. :-0
Joe: Thanks. Tried this. Twice. But no resolution. I still get crackling static with video and audio events. :-(

Have a great day,

yep, this is really annoying. Macbook Pro 2010 user here, Yosemite installed = sound not working!
I just thought I would add my little spark of frustration to the thread.

Thanks Etic, that worked perfectly for my sound issue after upgrade!!
On an early 2009 macPro the upgrade to Yosemite has effectively killed all audio. I have tried the usual fixes mentioned here: resetting PRAM twice, typing in the sudo killall coreaudiod command, sound output set to internal speakers. Sound still completely mute after having worked for a brief period. Go figure.
I had the same issues but then followed steps discussed here http://support.apple.com/kb/PH18958?viewlocale=en_US&locale=en_US and solved the problem.
I have the same problem. However, when I go to preferences to change to sound output, my internal speakers are not listed at all. I can't seem to find any advice to deal with this - any help, please?
I Have the 2010 macbook pro. I did a PRAM reset (can't remember the keystroke order, check online!). Thwe first time it didn't work, but I read somewhere, maybe here, that you need to do a PRAM reset twice. The second time it worked. Well the internal speakers work now.
I had problems with audio sync on every video I tried. (locally played, youtube, etc) It starts with about a two second lag, and may get as bad as 7 seconds!
In a seemingly unrelated problem, If I tried to save a photo out of a browser, download an app, etc.. The access to disks was dog slow.
Further, I had the well known Wifi problem reported all over the web.
These problems persisted even after the latest update to 10.10.1
I have an SSD with Yosemite on it, but I had recently CCCd from a spinning mac drive which was Mavericks. Then I updated the SSD to Yosemite.
As a Sanity check, I rebooted from the old spinning mac drive into Mavericks, and just like magic, my chronic problems disappeared! All of them!
I have since CCCd the SSD back to Mavericks, and my Mac Mini is now lightning fast... no exaggeration.
In my opinion, this is a software-hardware interface or I/O software issue, which affects all devices: Wifi, HDD, Sound, Video, Bluetooth, and anything else you may have attached. I also feel that this “fix” will be a long time coming due to its far-reaching nature.
Let me know if there is a fix, till then, Ill stick with Mavericks.
btw...I am running a Mac mini 3,1 (early '09 model) 8gb ram 250gb SSD
Question: OS X Yosemite - sound problems?
