-#### Note about using a USB device
+### Note about using a USB device
Dynamic handling of USB devices is not yet implemented, so you need to modify the 'hal-4a-2ch-generic-usb.json'
to change the `uid` value in `metadata` section and `path` values in `playbacks` and `captures` sections.
All these values should be replaced by the alsa entry path of your usb device, these entry are listed
under directory '/dev/snd/by-id/...'.
+### Selection of the hal loaded at binding launch
+
+Currently, the 4a-hal binding will try to launch a hal for each json audio configuration
+files found in path specified with CONTROL_CONFIG_PATH (an audio configuration file should begin with 4a-hal-*).
+If you don't want a hal to be launch with the binding, you can just rename/remove the corresponding
+audio json configuration file.
