However, because the EVB is registered with the PC as an "Audio Device,"sound from inside the PC may automatically be routed to the Nuvoton EVB. The EVB isregistered as a USB audio device, because it has the capability to receive an audio stream overthe USB bus.Thus, after plugging the EVB into a PC, audio inside the PC may appear to stop working or bechanged in ways that are surprising. Managing the PC audio routing will be especially importantif it is desired to use the PC as an audio source as part of the EVB evaluation process.Therefore, it is important to understand how to manage and control the PC built-in software andhardware audio features. What happens automatically, and the details of how to manage audioinside the PC will vary depending on the Windows version and specific PC hardware. Furtherdetails may be different if other audio hardware and or software has been installed on the PC.In all Windows systems, the management of audio is similar. This is typically done using the"Control Panel" option in the Start Menu, and then selecting the appropriate audio control icon ormenu item. It may also be possible to access the PC audio control panel by clicking or right-clicking on the speaker icon in the Task Bar, normally at the bottom of the PC screen.After activating the audio control panel, there will be various options. There will be an option forrouting sound to and from the PC, and in this option there will be a list of possible audio devices.The Nuvoton EVB is registered as an "Audio Device." It is possible other audio devices attachedto the PC may have the same or similar name. The Nuvoton EVB can be identified in this caseby unplugging/replugging into the PC to see which item is changed in the list of audio devices.Again depending on the Windows system and configuration, any selection made in the controlpanel may later be automatically changed by the PC system. Also, media player software maynot immediately recognize that the PC audio path has been changed. It is best to quit and thenrestart any media player application after making a change to the audio routing using the PCcontrol panel.
