1.当前我使用的kernel 是4.19 2.使用的是kernel 自带的7118 驱动,没有更改 3.使用的是I2C mode ，I2c 已经正常通讯 4.Linux kernel DTS 配置如下，使用的是I2c mode 、I2S mode：同理：根据7118 spec 上写的，如果7118 走i2s mode，必须走从模式，SOC 当做主。如下是数字miC 正常work 的CLK 频段硬件设计如下： 1.接两个数字DMIC 2.硬件电路如下...

主从节点重配对不适配问题 0
Not Answered

现在的问题是一套已经成功工作的主节点跟从节点，主节点上载有喇叭，保持从节点不变，更换一台新的陌生的主节点（这边无法操控，什么都不知道，只知道是主节点），就主节点发现不了从节点了，或者偶发问题：发现了节点，这个新的主节点喇叭也无声音输出（因为从节点上行音频信号过去的），是A2B协议没对接上吗，所以想问A2B在不同芯片选型上的协议具体是不是有哪部分不同（缺失了协议层的资料？）或者是我们这边A2B在哪里的配置不通用？

ADAU1452 Compressor – How to obtain real-time gain reduction (attenuation in dB) for MCU display 0
Answered

I am working with ADAU1452 and SigmaStudio built-in compressor block. My requirement is to read the real-time gain reduction value – the amount of dB the compressor attenuates the original audio signal, so I can display this value on my MCU UI. I have...

ADAU1701在使用物理键通过MCU进行 EQ切换时候出现爆音及DAC静音无法恢复的问题 0
Not Answered

我们在使用 ADAU1701 时遇到两个问题，求助 1. EQ 切换爆音通过 Core Register (0x081C) 的 Safeload 接口（地址 0x0810-0x0819）更新 5 个 Biquad 系数时，IST 置位后 50ms 内未自动清除（DSP 程序未编译 Safeload 模块）。回退到直接写 Parameter RAM 的方式，每次写入前设置 DAM=1，写入后清除 DAM=0。由于需要连续更新 5 个 Stage，每个 Stage 都做一次 mute/unmute...
