Under the Windows Vista operating system, it is necessary to select a specific sampling frequency because the sampling frequency cannot be changed on nearly all application software.

To set the DAC sampling frequency:

1.Open the Sound options from the Control Panel. (Start→Control Panel→Sound)

2.Open the speaker properties of the USB audio codec from the Sound options and select the Advanced tab, as Figure 3-5illustrates.

3.Select the desired DAC sampling frequency from seven options: 8 kHz, 11.025 kHz,16 kHz, 22.5 kHz, 32 kHz, 44.1 kHz, and 48 kHz.
