【已解决】关于tlv320采集音频数据

本帖最后由 goodman 于 2016-5-16 16:07 编辑

我这有一个挺基础的音频问题，麻烦大神们帮忙看一下

音频源----  tlv320 ------- hi3531

执行例程时， 例程基本上没有动过，完全用的sdk的代码。  我量了sio和TLV320AIC31的data_out管脚，是有波形随声音变化的， 但是为什么我采不到数据呢？

# ./sample_audio

/************************************/
press sample command as follows!
1:  start AI to AO loop
2:  send audio frame to AENC channel from AI, save them
3:  read audio stream from file,decode and send AO
4:  start AI to AO(Hdmi) loop
q:  quit whole audio sample

Set aic31 ok: bMaster = 1, enWorkmode = 1, enSamplerate = 8000
Ai(3,0) bind to AencChn:0 ok!

open stream file:"audio_chn0.adpcm" for aenc ok
bind adec:0 to ao(4,0) ok

please press twice ENTER to exit this sample
SAMPLE_COMM_AUDIO_AencProc: get aenc stream select time out
