[meta-freescale] Question about hdmi audio playback

[Ray・Bloodworth]

Hi,  everyone

    I'm trying play wav files with hdmi monitor.
    Platform: MCIMX6Q-SDP

    I checked sound card with command line:
# aplay -l 
**** List of PLAYBACK Hardware Devices **** 
card 0: wm8962audio [wm8962-audio], device 0: HiFi wm8962-0 [] 
Subdevices: 1/1 
Subdevice #0: subdevice #0 
card 1: imxhdmisoc [imx-hdmi-soc], device 0: i.MX HDMI Audio Tx hdmi-hifi-0 [] 
Subdevices: 1/1 
Subdevice #0: subdevice #0

routing sound stream to wm8962audio is fine:
 aplay -t wav -D hw:0,0 Noise.wav

But a error occured with hdmi: 
aplay -t wav -D hw:1,0 Noise.wav 
aplay: main:696: audio open error: Invalid argument 

Could anyone help me with this issue?

BR
