Hi, all
I have a wm8731 chip in my board , which connected the bf527 by SPORT 1. I found there are a ALSA wm8731 driver in the 2009R1 sound driver. How to use it? I enable the option Build all ASoC CODEC driver, but when the board start , it report no sound card found , and no /dev/dsp could be found under /dev. Below is the dump,
/////skip
Advanced Linux Sound Architecture Driver Version 1.0.18rc3.
ASoC version 0.13.2
ALSA device list:
No soundcards found.
/////skip
ls: /dev/dsp: No such file or directory
Need I choose SoC I2S Audio for the ADI BF5xx chip option also? but, when I enable that option ,I got a compile error like below,
MODPOST 32 modules

we dont test any wolfson codecs. most likely you need to write your own machine driver to bind a codec to a transport. please review the documentation in linux-2.6.x/Documentation/sound/alsa/soc/ or contact wolfson for support.
