取qxdm日志，先确保配置了adsp config log
在这里插入图片描述
重复现象

保存成isf文件
用QCAT进行解包，直接将isf文件拖进去，按如下方式解其中的流
在这里插入图片描述

根据adsp的流程1586是最接近设备的数据

80-n3470-4_d_hexagon_dsp_audio_pcm_bitstream_logging_through_qxdm_professional.pdf

在这里插入图片描述

解出来后生成如下文件,1586表示在上面audio path的代表图，0x11000即0x1000 即pri_mi2s_rx
定义中
80-nf774-3_b_hexagon_access_audio_front_end_api_interface_specification_for_avs.adsp.2.8.pdf这个文档中

最后面的应该是左右声道的标号

在这里插入图片描述

之后用cool edit 打开编辑查看
在这里插入图片描述

通过0x1586.pcm.0x1.0x1100.0x2.rx.wav 这个音频文件名取出1586 0x1000 0x1就可以知道audio path中0x1000这个path中的i2s,第2个声道的音频情况
