hdmi audio not working

Dear all,

 

i am using Linux version 3.10.17 on a similar Sabre lite board.

Using devicetree, setup similarly to sabre (equal for hdmi audio).

 

After boot, i see hdmi audio ASoC correctly setup.

 

 

bash-3.2# cat /proc/asound/cards

0 [cs42888audio   ]: cs42888-audio - cs42888-audio

                      cs42888-audio

1 [imxhdmisoc     ]: imx-hdmi-soc - imx-hdmi-soc

                      imx-hdmi-soc

 

Now, if i try to play some wav, with

 

aplay -D hw:0,1  test.wav

 

no sound is played on the target device over HDMI cable.

 

There can be some kernel issue, but it is still possible i have some hw issue, so, is there any way i can check if the audio is generated ?

 

Thanks
