We have previously had [similar reports](https://qa.fmod.com/t/when-the-media-volume-of-some-mobile-devices-is-set-to-0-it-reports-failure-when-fmod-is-initialized/17210/6) on Huawei, Vivo and some Samsung devices when the hardware volume is set to 0.  
Just to confirm whether this is the same issue you are having, can you please check that the volume is on and see whether this prevents the initialization failure?
