This possibly also affects Linux users. When I start an android emulator my system sound quality drops significantly.

This seems to affect audio output through HDMI but not when I switch to internal speakers - strange!

SDK Version: “Android SDK Tools” Rev., 25.0.7
Host CPU Model: Intel(R) Core(TM) i7-4700HQ CPU @ 2.40GHz
Device name: hw.device.name=Nexus 5

I notice the same behavior. For me. it started yesterday, not sure what changed.

Emulator version 25.2.2-3096464
Android version 7.0 (Nougat) - API 24.

I just updated to the latest images to see if it would fix the issue: it didn't. I'm now on image x86 Atom_64 revision 7

Mac os Sierra

Even I am facing this issue since I installed mac OS Sierra and also updated to Android Studio 2.2.1.

It appears to be the case for every heavy processing software. When I run a heavy game on my macOS Sierra, the Bluetooth audio quality dips significantly.

Yup, same issue here using Sony MDR-1000X on Sierra. Typical tropical dr oid.

Same issue, using Sony MDR-XB950BT.

I have noticed this as well. What happens is that my headphones are connected using the AAC codec, and then sometime during the initialization of the AVD, it changes the codec to a lower-quality one, that is used for old-style bluetooth headsets on phones (possibly SBC, possibly something else). This happens with my Sony MDR-ZX770BT. You can find out what codec you're currently using by option-clicking on the bluetooth menu item, and hovering over your headphones in the list. More about Mac bluetooth audio quality here: http://www.theghostbit.com/2015/03/force-mac-os-x-to-use-aptx-with-your.html

I believe the issue here is that Bluetooth switches to a lower (shitty) quality codec (SBC) when the Bluetooth mic is activated.

On my Mac I can simulate the problem by simply opening Sound Preferences while listening to music. This activates the Bluetooth mic and trashes the sound quality. According to my friend this is in the Bluetooth spec but I haven't verified that.

So if the an droid emulator could disable input there would be no problem. I've never used sound input in the emulator but others probably have.

I am to join to this annoying issue. Experiencing it using bluetooth Bose buds. Anybody came up with any workaround solution so far?

I'm facing the same issue is Mac os Sierra from last one month.
Temporary fix: Disconnect and reconnect the bluetooth headset.
This is very annoying.. Expecting someone to fix asap.

I was about to file this bug, I'm facing the same issue with Bose QuietComfort 35 on the macOS Sierra 10.12.2, emulator version 25.2.5-3567187 and Android SDK Tools version 25.2.5.

Just want to +1 that this is majorly annoying to the point that I've stopped using the emulator and reverted to my personal device for development and, more importantly, this is the best bug report title I've seen in 9 years. =D

+1 Having the same issue on Mac OS Sierra 10.12.2 , Android Studio 2.2.3 and a pair of JBL headphones.

Found a workaround from Reddit post.
Basically, turn off your mac bluetooth > run the Android simulator > turn on your bluetooth > connect the device.

At least it works for me.

Having the same issue on Mac OS Sierra 10.12.3, Android Studio 2.3.0

Having the same issue on Mac OS Sierra 10.12.3, Android Studio 2.3.0, Sony MDR-1000X.

It changes the codec used for streaming, maybe related to the microphone on the headphones

Having the same issue on Mac OS Sierra 10.12.4, Android Studio 2.3.0, JBL Charge 3.

the same here. Music quality drop off!  

Workaround: Go to System Preferences -> Sound -> Input -> select Internal Microphone

+1 Please fix :)

Please fix this, it makes me want to not use the emulator

Ditto #21. Simply change your system's input source back to Internal Microphone. This is a macOS/Bluetooth issue, not an emulator issue. The emulator triggers the behavior because it connects to the system's selected sound input source, which will be the bluetooth headset if you haven't changed it.

Genymotion doesn't have this issue though. Only the Google emulator.

#21, #27 - "Simply change your system's input source back to Internal Microphone."
Does not work for me. Sound remains broken. Only fix is to disable blue tooth, disconnect my device, and reconnect.

AFAIK this is a MacOS issue, same happens with the iOS simulator: https://stackoverflow.com/questions/37901761/bluethooth-headphone-music-quality-deteriorates-when-launching-ios-simulator

This should be fixed in the latest stable/canary versions. We have disallowed the emulator from using bluetooth audio input.

This is back in Mojave. Of note is that launching the emulator brings up an "Android Studio is requesting to use the microphone" permissions dialog.

Thanks, will look into it.

Informal poll: What if the emulator simply skipped bluetooth audio devices altogether? Does anyone require the emulator's audio to be played through bluetooth headphones?

@ #35 - Nope.

#35 That would not be an adequate solution if you use bluetooth headphones as your primary/only speakers which I imagine is most people in this thread.

#37: Is that most people then? I realize that if you're on a Mac Pro you might have BT headphones as your only speaker, and that's unfortunate. Indeed, this solution is not optimal. But would we want to make bluetooth audio bad for sure though (by trying to use those devices)?

(Until the "proper" solution, which would likely involve replacing the macOS audio backend for the emulator and would entail a lot of work).

#37, this was fixed prior to Mojave. Did something fundamental change in Mojave?

Also, disconnecting and reconnecting the headphones restores the audio quality (a few seconds after it reconnects).

#37: Yes, something changed in Mojave so that if a BT headset is used only as an _output_ device, the BT microphone gets auto activated even if the (for macbook) built-in internal microphone is selected by the emulator.

Is it possible to disable the microphone on an emulator?
Also, why does it seems to fix itself if you disconnect and reconnect your headphones?

Fixed in 28.0.11 and later:

Same problem with macos 12.3.

The bluetooth device seems to switch profil : A2DP to HFP.
