I don't think any audio mod will work for now until devices where the audio mod are taken from are updated/released with Oreo.
Any equalizer app in Play Store won't work too, complaining no AudioFX to work with.
A friend with N6P on stock Oreo has same problem, so it is not only M8 issue.
Reflash your device variant firmware or you can install this one (assuming you're not on T-Mob US network)
Also make sure you install the latest ROM not the early alpha release.
