I will add HDMI device to HiFi use case, but it won't do any actual mixer control because there's no alsa control for HDMI card. What can it do is only provide some information about the device's PlaybackPCM.
That is to say, nothing in udev rules should be configured for HDMI device, and HDMI device should be available in current ucm configuration.
