Dolby Audio gone after forced re-install of Win10 on Aspire Z3-715

BillH11103

Due to a bad MS update the other day, and no fixes working, I was forced to basically reinstall Win10 on my Aspire Z3-715 from a USB. Nearly everything came through fine, and I'm back running up to speed. That is, except for Dolby Audio. I've re-downloaded the audio drivers both from Acer and Realtek directly, as advised on several fix-it type pages. But, to no avail. The sound is working okay, but it definitely doesn't sound anything like it did before with Dolby Audio. What do I need to do to fix this issue?

Hi BillH11103,

I suggest you to uninstall and reinstall the Audio drivers.

Follow the steps to uninstall the Audio driver:

1. Press Windows Key + X key and click Device Manager.
2. Right-click on the Audio device listed and click on ‘Uninstall’.
3. Select the option to Delete driver software.
4. Restart the computer after its uninstalled. 
5. Press Windows key + X.
6. Click on Programs and Features.
7. Right click on the Sound software listed and click on Uninstall.
8. Restart the computer after its uninstalled. 

Now download the Sound drivers the manufacturer website and install it and check if it fixes the issue:

My experience had slightly different labels due to a different version of Windows, but in the end, Dolby is back rather painlessly. And, my sound options are singular. Not headphones (aka my Bose speakers) and the internal ***** speakers on the AIO. Thank you! Well done!

I have unstalled /installed AudioTech drivers twice from Acer site.  Device manager says the drivers are current and working properly - still no audio
