Audio on cell phone but not tablet

I don’t know if it’s just me not configuring a Tablet setting properly.

I have full audio from Towerbeta when using my Huawei P8 2017 lite (Nougat 7.1), but I have no audio from Towerbeta at all when using my Samsung Tablet A6 (Nougat 7.0)
I have delved into the audio settings on the Tablet and volumes are all set to MAX…
