      求助帖，望路过的大佬给指点一下，万分感谢🙏

      软件SDK: Tina4-V1.2 SDK
      硬件平台：百问网V853-AICT开发板
      4678e55d-486a-4772-8a33-82047ead51ad-42cdbce66e50d9005f5d9826d9256fa.png
      需求：我想要测试一下AEC效果
      当前操作过程：我编译运行了external/eyesee-mpp/middleware/sun8iw21/sample/sample_aec例程。程序运行结束后输出的ai_cap.wav只有一个wav头44byte大小。

      AEC调试记录：
      测试过程如下（异常是没有获取到aec后的音频帧，所以结果文件ai_cap.wav只写了个44byte的wav头）：
      初步定位：sample_aec.c:311行的ret = AW_MPI_AI_GetFrame(pCtx->mAIODev, pCtx->mAIChn, &frame, &stAecFrm, 500);
      返回值为ERR_AI_BUF_EMPTY，拿不到音频帧，所以ai_cap.wav输出为空文件。。。

      我当前的menuconfig配置如下：
      0c90faaa-88ae-4f6a-8b99-95668828bf9b-image.png

      我当前的asound.conf配置如下：

      pcm.!default {
type asym
playback.pcm “hw:{CARD=audiocodec, DEV=0}”
capture.pcm “hw:0,0”
}

pcm.PlaybackRateDmix {
type plug
slave {
pcm {
type dmix
ipc_key 1111
ipc_perm 0666
slave {
pcm “hw:0,0”
format S16_LE
rate 16000
channels 1
period_size 1024
periods 8
}
}
}
rate_converter “linear”
}

#pcm.resample rely on alsa-plugin and libspeexdsp. Select them in menuconfig if we want to use plugin pcm.resample.
pcm.resample {
type plug
slave {
pcm “hw:0,0”
format S16_LE
rate 16000
channels 1
}
rate_converter “speexrate”
}

pcm.CaptureMic {
type hooks
slave.pcm “hw:0,0”
hooks.0 {
type ctl_elems
hook_args [
{
name “MIC1 Switch”
preserve true
optional true
value 1
}
]
}
}

pcm.eq {
type awequal
slave.pcm “hw:0,0”
config_file “/etc/awequal.conf”
tuning_support true

          测试过程如下（异常是没有获取到aec后的音频帧，所以结果文件ai_cap.wav只写了个44byte的wav头）：
