APO keeps uninstalling from Audio devices

[Erik Malren]

I have been using Equalizer APO for years and I have this issue for a long time now. It happens at random times, where APO just uninstalls from one or all of my audio devices (bluetooth headphones, speakers, and microphone). I can usually instantly tell when this happens as the sound signature changes and when I open the Equalizer configuration editor I get the "No device matched "XXX speaker XXX" message on the device selector. To fix this I have to reinstall APO to the device using configurator and restart the PC which is starting to become really annoying.

It can happen anywhere from once a month to every day, and lately it feels like it's happening more often.

How do I stop this from happening?

I regularly observe a similar phenomenon but only on some Windows updates. These Windows updates have a tendency to reinstall audio drivers, leading to Equalizer APO being thrown out.

I suspect this would especially affect audio devices that use the standard Microsoft audio drivers (e.g. generic USB Audio, Bluetooth), as these drivers might be frequently updated with each Windows build.

Assuming you have the same problem, then I doubt anything can be done about it aside from adding a feature to Equalizer APO where it could automatically detect this situation when it occurs and reinstall itself automatically.

Yeah, I suspected it was audio driver related. And when you mention Windows update I believe that could be the case because I rarely restart or shutdown my PC other than when there is a update that requires me to do so. And this is usually the time I notice Equalizer APO is uninstalled from my speakers.

Yeah, would have been nice if there was an auto install APO feature on restart or similar.
