Q: Bluetooth audio lag

worked for me too, until machine went to sleep ...............

Same issue.  Will Apple fix this?  Does anyone know if there are Ubuntu drivers for a 13" mid 2010 Macbook Pro?  Love the hardware, but I have always been pretty indifferent to Apple software.  This makes me wonder about doing a ˆ"real" software update and just putting Linux or Windows 8 on the machine. 

Tried rebooting PRAM. Noticed a slight improvement, but lag is still there when I navigate while streaming music to my Jawbone blackbox. I have a Macbook Air with 2 Ghz, i7 8 GB. This was never a problem before. Annoying!

its been a while now since i did the clean install of Yosemite and i was too lazy to do another one for mavericks. I have to say though that the lag is much much less than it was before the clean install. Especially Quicktime seems to be ok. Ill leave it athis for now.

Btw, another Bluetooth bug - I now know that my headphones wont connect when my external display (with audio over DP) is conected. Only if i disconnect it, the Bluetooth Headset will conect. Also Safari cannot be open during this! Must quit before and then re-open.

So much fun to figure out this stuff. Deja-vu of my Windows days.

I've been experiencing the similar issues with my Bose AE2W bluetooth headphones when playing music after updating to Yosemite. Songs skip/stutter every other second making it a very frustrating experience. No issues with the headphones when paired/synced with other devices. The headphones are basically rendered useless until this gets fixed. I'm more than willing to work with a tech/engineer to help troubleshoot.

Has any1 fixed this problem? It's so annoying! Is it just Apple or other OS to? or is it the bluetooth?

Im using Outdoor Tech. Private and sometimes the lag may reach 1 second at it's worst. But then I restart so I don't know how far the lag can go.

page 17 and still no solution? Really, Apple?

Disabling 'Sound Check' in Music setting seems to work for me. 

I had the issue as well, then I tried something that worked for me.

I am using Beats headphones as well, via bluetooth on a Mac Pro (2013)

Open terminal

type in: sudo killall coreaudiod

enter your password

close terminal

problem fixed

reality is, coreaudiod is an issue with the last two OS's for Mac. No idea why, they say do a complete install again... where as I say, really Apple? How about a simple patch to fix your faulty coreaudiod?

doing the terminal tweak, your bluetooth sound issues will be resolved.

jamesrt, I'm not an OSX expert, but running that command resulted in my playing music stopping immediately, and I couldn't get sound working again still I opened Sound Preferences and started clicking around (or perhaps just waiting was what did it), but once the sound was working again, the skipping and popping and delay was immediately present. As with all the other supposed solutions, this did absolutely nothing for me. Did I do something wrong?

(Using MacBook Pro (Retina, 13-inch, Mid 2014) running 10.10.2 and connected to Jawbone BIG JAMBOX Wireless Bluetooth Speaker or LG Electronics Tone+ HBS-730 Bluetooth Headset and often also using Aerb® Wireless Bluetooth Speaking Mouse, usually playing music with Spotify, though the problem is exhibited for all audio, even the volume adjustment notification noise.)

Same problem here, bluetooth audio lag happens with my iMac 2011, MacBook Air 2013 and MacBook Pro Retina 2014, all running Yosemite 10.10.1. The audio lag happens when CPU load is high. For example, when I listen to music with iTunes on my MacBook Air and have the audio stream to my bluetooth-connected UE BOOM, by firing up multiple tabs on Google Chrome rapidly, the audio will start to lag a bit. Then by compiling code with Xcode, the audio will lag further. Usually when I pause the music, it continue to play for 5-10 seconds before it stop.

I think we might be able to mitigate this issue by renicing bluetoothaudiod with a higher priority. 

Actually disabling 'Sound Check' in Music setting only works for a while, as soon as I disconnected bluetooth or restart the phone, audio lag was there again. I'm using the iPhone 5s and JBL onbeat awake as speakers. The delay at the beginning of each song appears to be time it takes to transmit signal from the phone to the speaker, which is about 1.5 seconds, as soon as the speaker receives the signal it starts playing, but then it fast forwards at 2x normal play speed 1.5 - 2 seconds to catch up with the phone and that's how the audio lag problem is for me. I wouldn't mind it if it is just the first song but because it happens at the beginning of every song, it kind of makes the listening experience a lot less enjoyable.

I<3Music, oh, you're talking about an audio problem with an iPhone?! I thought all the messages in this thread were in reference to OSX + Bluetooth. It is interesting to hear the problem also affects iOS. That also makes me less hopeful this will get fixed… and more confused how Apple's "quality control" missed this issue that affects every computer I personally tested.

howanghk, can you either test or give more info on what you mean by "renicing bluetoothaudiod with a higher priority"? I'm fairly familiar with unix systems but not as much with OSX internals. How can we control this?

try running this in Terminal:

ps aux | grep bluetoothaudiod | grep -v grep | awk {'print $2'} | xargs sudo renice -10 -p

This command find the process ID of bluetoothaudiod, and then set its priority to -10 with renice. As bluetoothaudiod is run by root, and setting a negative priority value requires root privilege, we run it with sudo and thus it requires your password.

howanghk, that makes perfect sense. Somehow I never heard of renice and thought it was a typo at first glance!

Anyway, I ran the command, and the first minute is promising!! I can now pause and resume music instantly, and it seems good. I'll report back after some more use and testing. THANK YOU SO MUCH!

EDIT:: I'm an idiot and forgot I just switched to a hard cable an hour ago. I unfortunately have to take back my response.

howanghk, sending this as a separate reply in case people are only following the conversation by the e-mail notifications.

Unfortunately I stupidly forgot I had just switched back to physical audio cable in frustration, so when I ran howanghk's suggested command, I then tested and things seemed good… but switching back to bluetooth, the problem remains. :-(

EMOTIONAL ROLLER COASTER!
