'Emulator Error when launching AVD in Android Studio 3.0

I have a problem when I am trying to launch my AVD on Android Studio 3.0.
I have installed HAXM to run this AVD. The RAM allocated to run the HAXM is 2GiB.

Emulator: audio: Failed to create voice `goldfish_audio_in'
Emulator: qemu-system-i386.exe: warning: opening audio input failed
Emulator: audio: Failed to create voice `adc'    
Emulator: [7752]:WARNING:android/android-emu/android/base/async/AsyncSocketServer.cpp:99:Error when accepting host connectionError message: Unknown error

My AVD is a Nexus 5 API 23, CPU/ABI is x86. RAM is 512MB, VM Heap is 128 MB, and Graphics is Software - GLES 2.0. My PC's RAM is 5GB.

look in Android\android-sdk folder if it doesn't have the Platform-Tools folder containing the adb.exe

download platform tools again and deleted the previous one and extract the new one and see if it work
