Regarding ADAU1761

From past few days, I am trying to build Linux kernel for Avnet Zedboard using http://www.zedboard.org/sites/default/files/design/Ubuntu_on_Zedboard_Tutorial_v14.4_02.pdf.

Although I successfully build the standard configuration having HDMI but I don't want HDMI I want ADAU61 linein and lineout and I tried to build kernel again using audio_zynq branch but failed to get the sound.

During the boot time I am getting

adv7511-hdmi-snd adv7511_hdmi_snd.5: ASoC: CODEC <null> not registered

platform adv7511_hdmi_snd.5: Driver adv7511-hdmi-snd requests probe deferral

 

Also after booting I am getting the following result of aplay -l

***List of PLAYBACK Hardware  Devices***

card 0: ADAU1761 [ZED ADAU1761], device 0: adau1761 adau-hifi-0 []

Subdevices: 1/1

Subdevice #0: subdevice #0

 

But according to the document I should get both HDMI and ADAU1761.

Also when I tried to restore the ADAU1761 state as written in the document using alsactl restore –f zed_audio.state

I am getting the following result

 

No state is present for card ADAU1761

Found hardware: "ZED_ADAU1761" "" "" "" ""

Hardware is initialized using the generic method

/usr/share/alsa/init/default:60: value write error: Device or resource is busy

/usr/share/alsa/init/default:60: value write error: Device or resource is busy

/usr/share/alsa/init/default:239: value write error: Device or resource is busy

/usr/share/alsa/init/default:239: value write error: Device or resource is busy

No state is present for card ADAU1761

 

I am using the attached files for this

a serious help is required

Thanks in advance
