What setting are you trying to change from-->to. The original configuration varies with Volvo. I think the diesel series tend to have "EOR" from the factory.
My T6 S60 came with "EOE" from the factory. As I am not a big fan of the fake engine noise, I have changed mine to the disabled, "no EOE/EOR" setting. It works, removes the engine sound enhancement.
When you try changing these settings, it may be a good practice to try a reset of the ECM and the AUD (use the dropdown and the Hard Reset button on the ECU tools tab). If I remember correctly, it may have taken those ECU restarts to make the change take effect right away. There is some connection there, the ECM needs to send some engine data to the AUD unit, so it can play the correct "sound" through the speakers.
I did try EOR setting on my car, it did work but sounded very strange...I concluded that not all the settings are designed in to work for all the drivetrains, at the time I figured the EOR is primarily for the diesel engines, for noise reduction or just smooth out the sound. The EOE seems to be designed to enhance the petrol 4-cylinder, to sound perhaps more like a 6 cylinder or something more "luxurious". I prefer the more traditional sound without any electronic modifications ;-)
