equaliser stopped working

The equaliser has stopped working, I think it could have been after the recent system upgrade to Android 8.1.0 OPP28.85.13 on Moto G5. Everything's there, all the  sliders and controls but moving them makes no difference to the sound (I use a good quality Bluetooth speaker). Anyone else have this problem? Anyone have a solution?
