I cant get the audio codec "adau1761" to work.


Hw source ("compiled" with Vivado 2013.4):

Kernel source: git://

Kernel branch: xcomm_zynq

Kernel config: zynq_xcomm_adv7511_defconfig

Devicetree: zynq-zed-adv7511.dtb

Rootfs: linaro-precise-ubuntu-desktop-20121124-560.tar.gz


I changed nothing in the reference design.


The HDMI and everthing else is working fine but I cant get the sound or mic to work (linein, lineout, headphone ...). During bootup I see the alsa device and no error messages. But I cant see the sound devices in the ubuntu sound control "manger", on the other side it is visible in the alsamixer.


Is there a way to test the auda1761 within linux or in some other way? Do you have any ideas?
