Zhi Qiang Zhang (CHINA)
Message: 52825 I build the WM8731 driver, but I haven't had a WM8731 chipset. I tested the driver without the WM8731, do you think is that OK? I think it should be ok, because it just control the SPI and SPORT in BF531, I must can get something from that 2 ports, right?
I used a logic analyzers connect to the SPI and SPORT, when I play a song, 'mplay a.mp3', I got the SPI data, but nothing in SPORT, what is wrong?
I am using the svn version 4396.

i meet the same error
when i run "mp3play 1.mp3" ,the device can not stop unless i use "CTrl +C".
the sport has no BCLK signal out.
when i use cat ，the result is below：
root:/proc/asound/card0/pcm0p/sub0> ls
hw_params info status sw_params
root:/proc/asound/card0/pcm0p/sub0> cat status
closed
root:/proc/asound/card0/pcm0p/sub0> cat hw_params

Please only use and refer to the ssm2602 driver for bf527c chip. We don't have wm8731, never test it and have no plan to support by now.
