    Hi,

     

    I am having problems with the oscillator of my ADAU1702 not startup up. The problem is very comparable to the problem described in this discussion: (only ADAU1702 vs ADAU1701, my risetimes are even shorter).

    Hi there,

    When I try to probe the adau1702 codec from Linux, it complains that it can't find the firmware "adau1701.bin".

    If you inspect the kernel driver for the adau1701 https://github.com/torvalds/linux/blob/master/sound/soc/codecs…

  • ADAU1702  EQ频率偏移

    ADAU1702 在SigmaStudio中增加EQ,但AP扫出来的曲线与SigmaStudio中设置的不一致,频率发生了偏移。

    比如在100HZ设置高通,但是AP扫出来后在300HZ左右有个高通,频率发生了偏移。

    确认其他地方没有EQ设置。AP、采样率设置正确。
