7.3. Software Security
LibreSync software is secured using Crypto IC. Crypto IC is embedded either in the LS5B
module or the ACP. Crypto IC authenticates and allows only the valid LS5B software to boot
on the LS5B modules.
7.4. Source Switching
LibreSync enables user to switch the playback sources without any hitches. User can
choose to stream music either from AirPlay or UPnP server and the music streams on the
selected device from the source.
For example, A LS Device streaming AirPlay, starts streaming music from DLNA / DMR
when, the user selects music from Win 7 -Media Player to be played on the device.
7.5. Autosense of Audio CODEC
The new LS Firmware will automatically detect the presence of Audio CODEC in the
firmware.
If LS-SoC detects Wolfson CODEC (WN8904) on LS-I2C bus, then LS-Module takes care of
controlling the Audio CODEC and is applicable to LS5B EVK.
If Wolfson CODEC is not detected, LS-SoC does not control the Audio CODEC. Host MCU

APP.
