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

In which format is the audio in this *.wav file? It's quite possible
that it is not supported by imx-hdmi-soc, in which case you can try with
gstreamer using audioconvert (gst-launch filesrc location=Noise.wav !
/wavparse/ ! audioconvert ! /alsasink).
Kind regards

I have a question about this "gst-launch" command.
How dose this command line routing sound stream to imx-hdmi-soc with alsasink?

Yeah, I forgot to include the `device' attribute. The correct command
would be:
gst-launch filesrc location=Noise.wav ! wavparse ! audioconvert !
alsasink device=hw:1,0
Kind regards
