HI, THere:
Recently we found out by default, all of preprocessing effects are commets
out in audio_effects.conf:
# Default pre-processing library. Add to audio_effect.conf "libraries"
section if
# audio HAL implements support for default software audio pre-processing
effects
#
# pre_processing {
# path /system/lib/soundfx/libaudiopreprocessing.so
# }
As a result, below error happens during one Hangout call:
This is normal because the library is not configred.
But we tested and found out Hangout removed the Near-end echo obviously, do
you know how it's done? Is't possible Hangout enabled the preprocessing by
another way, how we can turn if off?
We want to load vendor's preprocessing instead.
