With multichannel voice activation support in LSM, it could be possible that the input media format/hw_params to LSM would be different than the output media format/hw_params. This change decouples the input and output hw_params for LSM. The output hw_params are obtained through ALSA pcm_hw_params operation, whereas the input hw_params are obtained though the LSM_SET_INPUT_HW_PARAMS ioctl to LSM. At the same time, the below parameter IDs are added to send the channel information to LSM service: - LSM_PARAM_ID_MEDIA_FMT_V2 - LSM_PARAM_ID_LAB_OUTPUT_CHANNEL_CONFIG Change-Id: Ie53a087b0ec54e83c4eba93a0828f9bdd6cc147d Signed-off-by: Bhalchandra Gajare <gajare@codeaurora.org> |
