Hello,

While going through AK4114 support I have hit the constant AK4114_DIF2 in ak4114.h . I would say its value should be (1<<6) according to AK4114 datasheet.

This is current situation: #define AK4114_DIF2 (1<<5) /* Audio Data Control */ #define AK4114_DIF1 (1<<5) /* Audio Data Control */ #define AK4114_DIF0 (1<<4) /* Audio Data Control */

I think cards using this code should experience related problems. E.g. in juli.c and revo.c the constant #define AK4114_DIF_I24I2S (AK4114_DIF2|AK4114_DIF1|AK4114_DIF0) /* STDO: I2S; LRCLK, BICK = Input */

Wow, thanks for spotting out. Now fixed on HG tree.

is used, intended to set output serial data mode to I2S/slave perhaps compatible with ICE1712/24. This may be causing problems mentioned in revo.c:

#if 0 /* FIXME: ak4114 makes the sound much lower due to some confliction,

•    so let's disable it right now...
  

*/ #define BUILD_AK4114_AP192 #endif

Right, this might be the cause. Unfortunately, I have no AP192 board here to test. Hopefully someone can test it soon...

I am trying to add support for SPDIF-IN of AudioTrak MI/ODI/O addon card (ice1724 + ak4114), hopefully this will be a little step forward.

Let me know if you have any advance.

Thanks!
