Can someone help me with is ?thanks!

As others have said, the solution is disabling sound. Unfortunately, in recent Android Studio releases (I'm using 1.4) the option to disable sound has been removed from the GUI. To disable sound you can do it either by launching the emulator from the command line with the -noaudio flag, or by editing the AVD's config file and setting the following parameters:

hw.audioInput=no
hw.audioOutput=no

On Linux, I found that file at ~/.android/avd/myAVD.avd/config.ini

I've had the exact same problem and found a solution that works for me. In the config of the AVD I've set an extra flag "Audio playback support" to "no". I've also made sure the AVD has 1GB of RAM.

This worked for me.

For me, it was unchecking the Multi-Core CPU check box

Niels' answer worked well for me https://stackoverflow.com/a/7706018 in that the emulator stopped using 100% CPU (dropped down to 10-15%) Furthermore it had another useful "side effect". I noticed that playing video in Totem or music in RhythmBox would block while the emulator was running. VLC would play video but refuse to play the accompanying soundtrack for the video. As soon as the emulator was killed, music would start playing. Niels' answer to set "Audio playback support" to "no" prevents this issue. I am running Ubuntu 11.04 and Android emulator version 13.0 (build_id OPENMASTER-172639).

I had same issue on my macOS High Sierra and for me helps to create new AVD device and choose CPU/ABI = x86_64, not x86 in Android version dialog. Hope that helps.
