+# Default Volume of Amplifiers
+The binding currently supports two use cases for amplifiers.
+1. Amplifiers are initialized with a default volume. The head unit uses software volume 
+   to change the volume of streaming data.
+2. Amplifiers are initialized muted. The head unit uses hardware volume (e.g. HAL-MOST-UNICENS)
+   to change the volume of amplifiers remotely.
 
+Use case 2 is the default use case. If you like to use this binding without hardware volume support
+please adopt the ```config_multichannel_audio_kit.xml``` as explained below.

+<!--   - otherwise use "07 01 50" = default volume -->
