Open terminal and copy and paste or type this in



yes > /dev/null



Then press enter. 


Minimize terminal do not, I repeat DO NOT close terminal or you stop the command and have Audio. This command  is better then moving the mouse around at all times. Let me know if this helps or if you tried this before.

I tested on 2 Asus Motherboards thought it might be worth a try on yours. Too bad sorry I couldn't help. 


Might be an issue with your Motherboards Audio card. Maybe an upgrade is in order.

i have solved this problem ..  by setting the exact bus ratio and after that giving that command including " sudo yes > /dev/null " thanks to you all...

but i want set that command in start-up by making a small program for this.. i tried but .. i'm not able to get privilege access to that .. can anyone help in this...??



These Lines are by Niresh:

Do not use "sudo yes > /dev/null"

This is a wrong concept here, cause all that the yes command do is use processor exclusively (100%) you can simply check from activity monitor and its not needed here.

@ There you go! I created a script for you and you can download it from here:!IN5HjQQS!vy9SNtu5S6l0Q8JaSLPsm6-j6mu6-pO7yGiNXsQfApI

It's an app that you have to put in the startup option. To set it in startup go to "System Preferences" and then go to "Users and Groups" then select your Mac account and go to "Login items", click on the "+" and select the script that you downloaded and then you should be ready to go! The only thing is that everytime that you boot the pc you need to insert your password in order to run the script but it isn't a big problem. Hope that this helped you, maybe give a like to this post and let me know if it works.  :)

    • @Niresh i forgot to say that that error was given because i have a Samsung M2 NVMe 960pro. I tried to remove it and it kinda worked but with a lot of bugs even during the installation. I can't remember everything clearly now cause it's been like 4 months ago
    • Thanks. I Have One Ethernet And One Wifi.

    • How many network adapters do you have? Like WiFi or Ethernet? Post output of lspci -nn command
    • Unfortunately i dont have any Option to disable my Grahpic Adapter. Can i disable it in an other way? Like any Boot Flags?   EDIT: I did just an Update for my BIOS but it didn't add any Options to disable my Graphics Adapter
    • This issue is called Discrete Graphics issue of High Sierra, To bypass this you have to disable either Intel HD Graphics 630 or Nvidia GeForce GTX 1060 from BIOS, Check into your BIOS to see if you have any options to disable Graphics, Then try booting Keep me updated
