hi3516cv610 去除风扇声音，人说话声音正常输出不变声

hi3516cv610加了风扇散热，然后mic采集的地方离风扇比较近（大概a4纸长的一半），我对音频进行了vqe降噪处理，然后AUDIO_MICIN_GAIN_OPEN 开启 acodec_input_vol设置60db，其它的逻辑如下：
ot_audio_dev ai_dev;
td_u32 ai_chn_cnt;
const ot_ai_chn ai_chn = 0;
ot_aio_attr aio_attr = {0};
sample_comm_ai_vqe_param ai_vqe_param = {0};
td_void *ai_vqe_attr = TD_NULL;

/* 初始化VQE Talk参数 (复制自 sample_audio_ai_vqe_process_ao_init_param) */
aio_attr.sample_rate  = OT_AUDIO_SAMPLE_RATE_16000;  // Talk VQE使用16kHz
aio_attr.bit_width    = OT_AUDIO_BIT_WIDTH_16;
aio_attr.work_mode    = OT_AIO_MODE_I2S_MASTER;
aio_attr.snd_mode     = OT_AUDIO_SOUND_MODE_MONO;    // Talk模式使用单声道
aio_attr.expand_flag  = 0;
aio_attr.frame_num    = SAMPLE_AUDIO_AI_USER_FRAME_DEPTH;
aio_attr.point_num_per_frame = OT_AACLC_SAMPLES_PER_FRAME;
aio_attr.chn_cnt      = 1; /* 单声道 */

ifdef OT_ACODEC_TYPE_INNER

ai_dev = SAMPLE_AUDIO_INNER_AI_DEV;
aio_attr.clk_share  = 1;
aio_attr.i2s_type   = OT_AIO_I2STYPE_INNERCODEC;

else

ai_dev = SAMPLE_AUDIO_EXTERN_AI_DEV;
aio_attr.clk_share  = 1;
aio_attr.i2s_type   = OT_AIO_I2STYPE_EXTERN;

endif
