Usage of Input and Output Device in smartphone

Hi,
I`m developing an In-Game VoiceChat using Vivox.
In smartphone, there are several devices:
Voice, Voice Communication, Generic…

Which should I use?

I used “Default Communication Device” as input before, but top speaker of Android not sound after updating vivox.

Unity Version - 2021.3.6f1
Vivox Version - 15.1.160000

Hello, before anything else, I’d advise to update to the latest version of 15.1.18. That version of Vivox uses Smart Platform Audio Management to automatically select the optimal Android audio configuration based on the context.
