The audiomixer.h listed a set of input channel related functions:
But 'Speaker' , "Headphone', and 'A2DP' channels all reported t not to have INPUT support (from the audiodevice_detailed_t ). Are those input related functions are real? If yes, then they apply to which audio channel(s)?
Also, in the system setting for Sounds and Notification, there is a on/off toggle for the Headphone Audio Boost. Does anyone know how it this done using any of the published ndk API? Thanks.
Solved! Go to Solution.

The audiomixer input functions apply to those channels for which audiodevice_details_t.input is true, e.g. HEADSET, HANDSET, BTSCO (bluetooth headset), etc.
There is no way to adjust the Headphone Audio Boost from the NDK. It is a user option only.
