GDB supports source debug of dynamically loaded libraries, but user should be warn that the actual path to sharelib symbols is directly inherited from DLOPEN. As a result if you change your directory after binder start with --workdir=xxx then GDB will not find symbols anymore ``` Examples: # WORK when running in direct afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs # FAIL when using GDB with warning: Could not load shared library .... gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs ... warning: Could not load shared library symbols for ./build/ucs2-afb/afb-ucs2.so. Do you need "set solib-search-path" or "set sysroot"? ... ``` To debug sharelib symbol path: start your binder under GDB. Then break your session after the binder has loaded its bindings. Finally use "info sharedlibrary" and check 'SymsRead'. If equal to 'No' then either you start GDB from the wrong relative directory, either you have to use 'set solib-search-path' to force the path. ``` gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs run ...

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. ``` <!-- Register 7: Master Volume (Max Volume=07 00 00 and Min Volume=07 03 FF) --> <!-- - together with HAL-MOST-UNICENS binding use "07 03 FF" = muted after start --> <!-- - otherwise use "07 01 50" = default volume --> <I2CPortWrite Address="0x2A" Payload="07 03 FF"/> ```
