I'm trying play wav files with hdmi monitor.

Platform: MCIMX6Q-SDP

&nbs= p; I checked sound card with command line:

# aplay -l=0A
**** List of PLAYBA= CK Hardware Devices ****=0A
card 0: wm8962audio [wm8962-audio], device = 0: HiFi wm8962-0 []=0A
Subdevices: 1/1=0A
Subdevice #0: subdevic= e #0=0A
card 1: imxhdmisoc [imx-hdmi-soc], device 0: i.MX HDMI Audio Tx= hdmi-hifi-0 []=0A
Subdevices: 1/1=0A
Subdevice #0: subdevice #0=

routing sound stream to wm8962= audio is fine:

aplay -t wav -D hw:= 0,0 Noise.wav

But a error occured with hdmi:=0A
aplay -t wav -D hw:= 1,0 Noise.wav =0A
aplay: main:696: audio open error: Invalid argument= =0A
=0A
=0ACould anyone help me with this issue?

Yeah, I forgot to include the `device' attribute.
