Dolby Digital Plus Audio Driver Update
Dolby Home Theater User Interface If you have recently upgraded from Windows 8.1 to Windows 10, there is a high chance that the Dolby Home Theater is missing and you won’t even see the Dolby icon on Taskbar. This happened to my Lenovo IdeaPad U530 laptop, and the following steps solved the problem.
Solved: Lenovo Notebook model Z50-70 Issue: Dolby Digital Plus not working after recent update to Windows 10 update version 1709 build.
IMPORTANT:. Note that this fix is only to be applied on Lenovo computers which was once running Dolby Home Theater on Windows 8.1 and the program went missing or isn’t doing anything after Windows 10 upgrade. Sankat mochan hanuman newark.
In the process we are going to uninstall audio drivers and install it, so it is a good idea to create a System Restore point before proceeding with the following steps. Incase if something goes wrong you can revert to your earlier system state.
First thing to do is to check if your computer has some hints of corrupted Dolby Home Theater program leftover or not. So click on Action Center and then click All Settings. Hi Kiran, Like you, I lost the taskbar icons to Dolby Home Theater v4 on my Lenovo laptop when I upgraded from Windows 8.1 to Windows 10. I got the icons back and profile selector lighting up after uninstalling, and then reinstalling the app, however, it didn’t work.
In other words, I could change sound profiles and got nothing. The app isn’t actually working. Are you sure it is really working on yours? This app was my favorite of the apps that came with my Lenovo laptop.
As it wasn’t working, I downloaded an open source equalizer to fill in until I got it working. Now I’m wondering if that is the problem now. If someone responds that got the Dolby Home Theater v4 working using your method, I might try uninstalling the open source one.
However, I can’t ever do exactly what you did since I uninstalled the software, instead of just “repairing” it. Maybe I did something wrong, but I couldn’t get it to work.
As soon as I uninstalled the drivers, it prompted me to reboot. So, I wasn’t sure whether I was supposed to install the old audio driver first — it’s on on my D drive also — or reboot. I think I tried it both ways. My old driver is a Vista64 driver from 2012, and when that is installed, the sound doesn’t work, which is what I would expect.
When I reboot and it upgrades to the new driver, the sound comes back on. But still no Dolby Home Theater v4 icon in the lower right. I just use the same one as before, the one I created for the desktop, and the equalizer doesn’t show live, nor do any of the settings work, although it turns on and I can switch settings. I might recommend to anyone trying this that they set a system restore point before doing anything with the driver. Something seemed messed up and I ended up using a restore point from before the first major update to Windows 10 came in (not the initial upgrade to Windows 10 but a big update to the initial upgrade) so I ended up having to go through the whole download for the Windows 10 update, after doing a system restore which took over an hour.
One of the annoying things about Windows 10 is that it takes nearly 5 minutes to reboot, which is twice as long as Windows 8.1. Even so, there’s no going back for me. On the Lenovo website board, the initial post of the person who had this problem has over 500 views, and the Lenovo rep answered with a PROBLEM SOLVED by saying people who lost the Dolby Home Theater should revert to Win 8.1. LOL, I am not doing that. Other than the longer booting time and having to use an open source equalizer, I like too many things about Windows 10 to ever go back.
I can be quite the nutter in these matters, and would ordinarily try something different, like deleting the Dolby Home Theater app, and trying the driver thing again. But, this time I think I’ll wait. Hopefully, someone in my situation (who deleted their Dolby Home Theater app) will get your method or a variant of it to work, leave a comment here, and then I will try again. I appreciate your effort, and again, it’s possible that your tip would work, and I just did something wrong. You might add to your post that people are supposed to load the old driver without rebooting the first time it prompts you to after uninstalling the driver, if that’s what they’re supposed to do. Your post is the closest thing I found in the entire web re my speaker problem with my Z510.
Thank you It’s not quite a success yet, though. After doing the above exercise, I still get this message when I tried to open Dolby. “The current Dolby Digital Plus audio driver version is 7.6.4.9 and the software application expects driver version 7.3.2.2. Please install a valid driver and software application combination.” Is the old driver still saved in my drive d driver folder? How to identify if it’s the 7.3.2.2 version?
I’d appreciate so much any further advice and helpful insights:)).
