If you have encountered the “No audio device installed” error message or have no sound coming from the speakers connected to your PC, your issues may be related to the multimedia audio controller. If your multimedia audio controller drivers are corrupt or outdated, there is a high chance you will run into sound issues on your computer. In this post, we will tell you how to fix the “no audio device installed” issue in Windows 10.
The SM Bus driver is part of the chipset driver package. I suggest that you go to Intel's download site and update your chipset drivers. Afterwards, try to update your onboard video driver there. I am not sure if Dell supported Windows 7 for use with the 620. As title says, I have managed to install Win 10 on my late 2011 macbook pro. Unfortunately, Apple does not support these models anymore. Therefore, I am getting blue screen of death every time I install bootcamp driver. If you do not see an SM Bus Controller entry, your computer does not have an SM Bus Controller or it is not recognizing the controller. Restart the computer and perform these steps again. If you still do not see an SM Bus Controller entry, your computer does not have an SM Bus Controller. I installed Windows 7 on a user's Macbook Pro yesterday (Aug 2010 model I believe) using Boot Camp, then I used the Mac OS X disc to run the Boot Camp Drivers installation. I then restarted as normal and went about the myriad other installs, when I entered devices and noticed the '!' Symbol on the computer.

How to Remove the ‘No Drivers Installed for this Device’ Error Message?
As there are several issues that can be causing the problem, there are also plenty of ways you can try to fix it. These include:
- Updating the multimedia audio controller driver
- Uninstalling the multimedia audio controller driver
- Checking for available Windows updates
- Adding a Legacy hardware
We will go over these solutions one by one, starting at the top. If the first option does not work, proceed to the next solution in the list — and so on.
Now, before we get into the steps for each of the above fixes, we suggest you create a System Restore Point to protect your OS in case of the rare occasion that anything goes wrong.
The first thing you will need to do is make sure that System Restore is enabled on your PC.
Typically, this utility is always on by default, but if it has been manually disabled, you will need to turn it back on again. Here’s what to do:

- In the search bar, type “system restore” (no quotes).
- Select Create a restore point.
- Navigate to System Protection.
- Choose the drive you want to check and click Configure.
- Make sure Turn on system protection is enabled — this is needed for the System Restore Utility to be turned on.
Now, proceed to creating a System Restore Point:
- Right-click the Windows icon on your taskbar.
- Go to Control Panel > System and Maintenance > System.
- In the left section, select System Protection.
- On the System Protection tab, select Create.
- Type a description for the restore point you want to create (you can use a specific date or describe it as “before clean install”, for example).
- Click Create.
After you have created a restore point, we can proceed to the first solution.
Option One: Update the Multimedia Audio Controller Driver
An outdated driver can be the cause of many problems on your PC. It is, thus, very important to keep your system drivers up to date. There are two ways in which you can go about updating your multimedia audio controller driver: you can do it manually or automatically.
Updating your drivers manually is typically recommended for more experienced users. You will need to locate the outdated drivers yourself, download the latest available versions from the manufacturer’s website, and install them on your PC. This can be quite a time-consuming process. Plus, if you do make a mistake when updating your drivers, this can result in more and bigger issues for your computer.
