Q: Sudden loud static noise on bluetooth headset

Yes!  I am experiencing the exact same thing.  Same headset (LG Tone+, HBS 730). I have a MacBook Pro, from mid-2010, running 10.10.2 Yosemite.

It only started in the last few days, though I've been running Yosemite for a little while now. I had previous bluetooth issues with Yosemite, specifically that the audio would get out of sync with whatever video I was watching.  Upgrading to a later build of Yosemite seems to have fixed that, though.

The loud static sound is new, though.  Based on the fact that the headset works fine in every other instance I use it (I have two phones that I use with it frequently), I'm fairly certain the issue is with Yosemite. 

Confirm this horrible bug. Macbook air late 2010, Sony SBH-20 headset. Now I'm really scared to use my Bluetooth headset

This is happening to me as well. Had the laggy bluetooth issue with the Yosemite update, but that was fixed in 10.10.2 that I downloaded today. My excitement about the fix was short-lived, however, as my earholes were soon accosted with "crank it up to 11" static. Please fix!

I have the loud static problem over bluetooth with a Jawbone Jambox speaker when I wake up a sleeping Macbook Air. If I disconnect via the Bluetooth menu or by power cycling the speaker audio will be normal for a while if continuously used.

This problem started when I applied the 10.10.2 update. From the release notes "Improves audio and video sync when using Bluetooth headphones" so a change was made to Bluetooth in that update.

Same loud 'static' problem after 10.10.2 update. Just updated iTunes (to 12.1.0.50) a bit ago and my Mac Air late 2010 still has load static problem. BT connecting tp samsung sound bar (HW-FM45C).Last example was coming out of screen save. Prior example was while in screen save (elsewhere in hse). FWIW, WiFi is on as well.

I also have started experiencing this since the latest update to 'fix' the bluetooth.

This has happened on both my Retina MacBook Pro and my MacBook Air, doing different things... My speakers are a Creative Bluetooth 2.1 system. Seems to happen when going from full screen YouTube to normal sized player.

Same problem here. Headset is Sony MDR-10RBT. The machine is a MacBook White, from mid-2009, running OS X 10.10.2.

I haven't experienced it before upgrading to 10.10.2, but haven't used the headset much on Yosemite because of the lag/sync problems.

Same issue here
I'm using a high end amp connected via bluetooth to my rmbp (latest update) it was fine till I updated.
Not sure if related to iTunes or OS X,
when muting the sound it stops.
When disconnecting bluetooth and reconnecting, it stops.
And when pausing the song on iTunes and play again, it stops.

Please fix.
It's happened 3 times in the last hour, with a heart attack each time

Thanks,
Teo

Same problem for me using Bose Soundlink 3 Bluetooth speaker on MacBook Pro Late-2011.

Seems to occur at random times but has happened both when listening to music through Spotify and on Youtube.

Same problem here after update 10.10.2

I have a Macbook Unibody Late 2009 with Philips SHB7000WT bt headphones.

BT audio already wasn't great before the update, now it's even worse, i'm always scared to hear that noise.

I use headphones everyday for work so...

I never report on bugs but this time that's very very annoying

Same problem using Ruark MR1 external speakers connected via bluetooth. MacBook late 2008.

Occurs from any audio source and often if the screen has gone to sleep whilst audio is playing, wake it up and you get the static stream. Pausing and waiting can fix it, or turning the speakers and bluetooth off and back on again.

Same issue. MBA mid-2012. Jabra Revo Bluetooth Headset.

Happened after the latest Bluetooth lag fix.

Just seems to happen mid-song. Unpredictable.

Bluetooth audio is un-usable in this state....

I am also having this problem since updating to 10.10.2.

I am on a 2011 Macbook Pro. And it usually makes the noise soon after waking my laptop.
