This is the reason why most people explore the world of third-party equalizers, and this is where Equalizer APO comes in.
We take a look at how to fix some of the main issues with Equalizer APO on Windows.
Causes Of Equalizer APO Not Working
There could be any number of causes that mean Equalizer APO is not working on your Windows computer.
You will need to find out the right cause of the problem first, and then you can sort out the issue.
Blocked By Firewall
If you have an antivirus program installed on your PC, chances are it has blocked access to the audio device.
The solution here is simple: disable the firewall for a few minutes so that the audio driver can use the microphone.
You may also need to add an exception to the firewall to ensure your Equalizer APO is running.
Disabled Device Enhancements
Equalizer APO needs certain enhancements to work properly.
These enhancements include support for surround sound and support for Dolby Digital 5.1 Surround Sound.
When these features are disabled, they cannot be used by any other software.
No Sound At All
Sometimes, there is no sound coming through the speakers, even though the volume is turned up all the way.
In this case, check if the audio drivers are updated. If the drivers are outdated, update them.
Audio Hardware Acceleration
When you have hardware acceleration for audio enabled in your computer’s properties settings, then you may find that Equalizer APO isn’t running on your machine.
You need to disable hardware acceleration and try again if this has resolved the issue.
