Realtek AC'97 Audio Codecs driver is typically found in some of the following systems:

Sony Vaio
Dell Laptops and Desktops
Acer Systems
Toshiba Systems
Various Netbooks

But make sure you have all of the settings in the playback devices right and if that doesn't work try the AC97 header. A quick google search led me to find your motherboard manual. You should have the front panel plugged in here. Thought I should note that HD Audio is. The front panel audio header on an Intel® Desktop Board lets you connect to a front panel audio module built into a system chassis. See the header pinout configuration below for connecting a chassis with Intel® High Definition Audio (Intel® HD Audio) or AC'97 (Audio Codec '97) audio.

AC'97 Audio Codecs (Driver Only) on 32-bit and 64-bit PCs

Indesign cs6 8.1 update. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from drivers without restrictions. AC97 Audio Codecs (Driver Only) 4.06 is available to all software users as a free download for Windows 10 PCs but also without a hitch on Windows 7 and Windows 8.

Compatibility with this software may vary, but will generally run fine under Microsoft Windows 10, Windows 8, Windows 8.1, Windows 7, Windows Vista and Windows XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Realtek.

AC'97 (Audio Codec '97; also MC'97 for Modem Codec '97) is an audiocodec standard developed by Intel Architecture Labs in 1997. The standard was used in motherboards, modems, and sound cards.

The specification covers two types of component, and the 'AC-link' digital interface between them:

an AC'97 digital controller (DC97), which is built into the southbridge of the chipset, and
an AC'97 audio and modem codec, available from several vendors, which contains the analog components of the architecture.

Robot os. AC'97 defines a high-quality, 16- or 20-bit audio architecture with 5.1 surround sound support for the PC. AC'97 supports a 96 kHz sampling rate at 20-bit stereo resolution and a 48 kHz sampling rate at 20-bit stereo resolution for multichannel recording and playback.

Integrated audio is implemented with the AC'97 Codec on the motherboard, a Communications and Networking Riser card, or an audio/modem riser card.

In 2004, Intel released Intel High Definition Audio (HD Audio) which is a successor that is not backward compatible with AC'97.^[1] HD Audio has the capability to define up to 15 output channels, but in practice most motherboards provide no more than 8 channels (7.1 surround sound).

Revisions[edit]

AC'97 has had several revisions:^[2]

AC'97 1.x compliant indicates fixed 48K sampling rate operation (non-extended feature set)
AC'97 2.1 compliant indicates extended audio feature set (optional variable rate, multichannel, etc.)
AC'97 2.2 compliant indicates extended audio, enhanced riser audio support, and optional Sony/Philips Digital Interface Format
AC'97 2.3 compliant indicates extended configuration information and optional jack sensing support

AC'97 revision 2.3 enables Plug and Play for the end user. This revision provides means for the audio codec to supply parametric data about its analog interface much like Intel High Definition Audio.

AC-Link[edit]

The AC-Link is a digital link that connects the DC97 (the controller) with the audio 'codecs.' It is composed of five wires: the 12.288 MHz clock, a 48 kHz sync signal, a reset signal, and two data wires which carry the actual audio data: sdata_out and sdata_in. The first four are outputs from the controller, while sdata_in carries input from the codec. The link carries a bidirectional serial data stream at a fixed bitrate (12.288 Mbit/s) between the controller and one or more codecs.

Each 12.288 Mbit/s stream is divided into 256-bit frames (frame frequency is 48 kHz). This is therefore a time-division multiplexing scheme.

Every frame is subdivided in 13 slots. The first (slot 0) is 16 bits long and contains validity flags for the remaining slots, while the remaining 240 bits are divided in twelve 20-bit slots (slots 1–12), used as data slots.

Slots 1, 2 and 12 are used for non-audio data, while slots 3–11 carry up to nine channels of raw pulse-code modulation audio signals. Normally, six channels are used for 5.1 surround sound, and three channels are available for modem use. However, slots can be combined to provide a 96 kHz sampling rate for the L, R and C channels.

Lower sample rates (such as 44.1 kHz) are implemented using a handshake protocol between the controller and codec which skips data during certain frames. (This capability depends on the codec. Alternatively, sample rate conversion could be performed in the DC97 (controller) or in the software driver.)

Codec chips[edit]

Codec chips have an AC'97 interface on one side and analog audio interface on the other. They are usually small square chips with 48 pins (48-pin QFP package). They are D/A and A/D or only D/A.

Front panel connector[edit]

Computer motherboards often provide a connector to bring microphone and headphone signals to the computer's front panel with standard color jack. Intel provides a specification for that header; the signal assignments are different for AC'97 and Intel High Definition Audioheaders.^[6]

Operating system support[edit]

AC'97 is supported by most operating systems, such as Windows and Linux. Under DOS, applications access the sound hardware directly instead of through the operating system, and most DOS applications do not support AC'97. 64-bit versions of Windows 7 and later require a third-party driver for AC'97 support.^[7]
