Here:
https://github.com/android-ia/device_intel_mixins/blob/master/audio/hsw_alc282/audio_policy.conf
hsp {
outputs {
hsp {
sampling_rates 44100
channel_masks AUDIO_CHANNEL_OUT_STEREO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_OUT_ALL_SCO
}
}
inputs {
hsp {
sampling_rates 44100
channel_masks AUDIO_CHANNEL_IN_MONO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_IN_BLUETOOTH_SCO_HEADSET
}
}
}
