Audio Mods Stops Google Maps Voice Level (Volume) Control

Currently running MOAR V7.0 (everything you could want in control of your phone) Have tried quite a few audio mods to improve music quality. Viper4android, Extrememusic, etc. All of them remove the ability in google maps to change the "Voice Level" control which allows you to set to louder, normal, softer. The option no longer appears in settings/navigation settings. I need it set to louder to match to my Waze volume levels since I use both apps depending on travel situation. I really like the audio mods, but also need to control the volume setting in google maps. Anyone else notice this, and what can I do to rectify? Thanks so much for your help. Daily reader, first time question.
