ICH7-M Audio Codec ’97 Controller
The Audio Codec ’97 (AC’97) controller integrated into the ICH7-M complies with AC’97
Component Specification, Version 2.3. The AC’97 controller is integrated to a RealTek
ALC655 audio codec. The RealTek ALC655 is in turn connected to on-board audio
connectors, which are then connected to compliant audio devices. The RealTek ALC655
is a 16-bit, full-duplex AC'97 Rev. 2.3 compatible six-channel audio codec. The codec and
the audio connectors are shown in
