Intel Desktop Board D945GCPE Technical Product Specification 1.7 Audio Subsystem The board supports the Intel High Definition audio subsystem based on the Realtek ALC662 audio codec. The audio subsystem supports the following features: • Line out and Mic in functions for front panel audio jacks • A signal-to-noise (S/N) ratio of 95 dB • Independent stereo audio playback from back panel connectors and Intel® High Definition audio front panel audio header. NOTE The use of AC 97 front panel audio headers is not recommended if you plan to obtain Microsoft Windows Vista certification. 1.7.1 Audio Subsystem Software Audio software and drivers are available from Intel's World Wide Web site. For information about Obtaining audio software and drivers Refer to Section 1.2, page 15 1.7.2 Audio Connectors The board contains audio connectors/headers on both the back panel and the component side of the board. The front panel audio header provides mic in and line out signals for the front panel. For information about The location of the front panel audio header The signal names of the front panel audio header The back panel audio connectors Refer to Figure 9, page 38 Table 9, page 40 Section 2.2.1, page 37 1.7.3 Four Channel Audio Subsystem The four channel High Definition audio subsystem includes the following: • Intel 82801GB I/O Controller Hub (ICH7) • Realtek ALC662 audio codec • Microphone input that supports a single dynamic, condenser, or electret microphone The back panel audio connectors are configurable through the audio device drivers. The available configurable audio ports are shown in Figure 3. 22
