 Now you should ear the sound coming from the HDMI display (obviously your device must have the speakers!).
+FIXME There is a problem with the **alsa-restore.service** which should be responsible for saving the ALSA controls status on shutdown and restore them on bootstrap (executing the commands **alsactl store** and **alsactl restore** respectively). Till now I was not able to make the restore working automatically: it seems that the S/PDIF output is muted just before the save, so at bootstrap the alsactl will always restore a muted audio system.
