When hotplugging the HDMI cable after booting the target, pulseaudio doesn't
load the HDMI sink. This commit fixes this by adding a udev rule and a script
that prompts pulseaudio to detect the HDMI sound card and load its sink, as
well as making it the default one.
If alsa-utils is available, a faulty command is run to load the card without
any audio output. Otherwise, module-udev-detect is unloaded and reloaded.
This is based on commit
