Hi Sascha,
I am having trouble implimenting the wm8731 codec with the i.MX21.
I have read your article https://lwn.net/Articles/363406/ which does not
fill me with confidence on this.
It is at the stage of finding the i2c device, and setting up the
transmit line for AC97, I am not very experienced with audio and would
appreciate any advise possible?
Here are a few traces I have added:
[ 2.935589] wm8731_i2c_probe: i2c_set_clientdata
[ 2.989318] imx_ssi_init
[ 2.997084] imx_ssi_probe
[ 3.007482] imx_ssi_probe
[ 3.015846] setup_channel_to_ac97
[ 3.029115] imx-fiq-pcm-audio imx-fiq-pcm-audio.1: failed to claim
fiq: -16
[ 3.049930] imx-fiq-pcm-audio: probe of imx-fiq-pcm-audio.1 failed
with error -16
[ 3.075173] ALSA device list:
[ 3.084401] No soundcards found.
Attached is a schematic of our interface.
Many thanks,
Jon
