7 Quick Start

Configure the AC-MB for the USB audio (TDM) and the TAA3040EVB for the onboard microphone input.

All configurations for this example are done on the audio configuration tab. In the Audio Configuration block in the lower right portion of the audio configuration tab (as shown in Figure 7-1), select a word length of 16 bits, and enable the ASI output channel 1.

The default state for the TAA3040 is standby mode and, with the exception of the channel digital volume, all device configurations must be done in standby mode. The TAA3040 does not provide a digital audio output in standby mode. Figure 7-3 shows how to change the mode from standby to active.

When active mode is enabled, any controls not configurable in active mode are grayed out. These controls can be changed again when the device is brought out of active mode. Figure 7-4 shows which controls are disabled.
