If you managed to get it working reliably on the output device then we can concentrate on getting the mic working. In the past SteelSeries APO's also didn't play nice with Equalizer APO. Usually this was the mic part of a headset. But the last couple of years I hardly ever need to help people with this specific SteelSeries mic issue so everything is okay there. I'll see where i can find traces of clownfish's APO somewhere I hope you can clean things up.
By default Equalizer APO processes the audio stream on the post mix side. If this side stays red then we can set 'Equalizer APO stage' to 'Before' on the Peace Effects panel. But good to hear that SFX/MFX does the trick. So are you able to use Peace on your headphones (try the pre amp slider)? If not after trying Clownfish then something is terribly wrong. Usually such an issue is caused by a Windows update. In this case I don't know what. I'm guessing the developer of Equalizer APO doesn't know...
A further look at the uninstall icon makes me believe it's from the installer/uninstaller app NSIS (Nullsoft Scriptable Install System). So Clownfish may or may not use Equalizer APO. We can't tell unfortunately. But I think we can conclude it's an APO specially made for the mic. If so, it doesn't tell us why Equalizer APO doesn't any longer work on other (output) devices. At least the default output device (laptop speakers/headphones or PC output jacks) should work. Unfortunately, the issues the...
It depends if Clownfish uses the generic app icon as shown in the attached image. The uninstall app of Equalizer APO also shows this generic icon. It only reported a problem once, which was with the registry after i ran your bug fixing tool. Sorry, I don't understand. Did the Device Selector pop up a message saying it had a problem with the registry?
Btw. Your reply is just fine. Short replies can be more difficult for problem spotting. I prefer longer ones.
Yes clownfish is most likely an APO, since it has the same executable for uninstalling as equalizer APO What do exactly mean by 'same executable'? Perhaps Clownfish uses Equalizer APO or a clone. If so, this is a huge problem. The Windows registry would be mixed up, Equalizer APO (and so Peace) won't work. Anyway, after the Device Selector did its testing, does it report problems?
I guess Clownfish Voice Changer is an APO (audio processing object = sound effect/enhancement). This could mean that Equalizer APO can't work together with Clownfish Voice Changer. Looking at website of this there isn't any information what it exactly is. Did you uninstall it and afterwards Equalizer APO (thus Peace) still didn't work after installing Equalizer APO on the target audio devices?
That shouldn't happen. Could you attach your Peace configurations (.peace files) on which this issue happens, to your next post? You'll find them in c:\program files\equalizerapo\config. And attach your peace.ini file which is located in the same folder. I hope to get the same issue with your files. To be sure, are you're using Peace version 1.6.9.11?
