Our partner have a question about i.MX6Q HDMI output.
They modified /etc/asound.conf as following to output audio data to HDMI.
pcm "hw:1,0" // <-- modify from hw:0,0 to hw:1,0
Now, Yocto BSP (L3.10.17_1.0.0-ga) outputs no i.MX6Q HDMI audio siganal when no video is playback.
Actually some HDMI receiver output noise after video playback is finished if i.MX6Q outputs no audio signal.
So our partner want to change it to output "silent data" when no video is playback.
Could you let me know how to modify?
