hal_most_unicens.c: Set amp volumes initially
Sets the default values for the amps to a predefined value of 80%. The previous implementation requested the values from ALSA mixer controls which may cause to be muted when someone has reduced the volume on a previous boot. We found this too risky for the current state and wanted to make sure that we find the same volume levels after each system boot.
