After clean reinstall, it's hard to find the correct drivers for AC97.

No it isn't. Everythings fine with them.

20 or 16 or 24 bit?[edit]

I'm confused. Are you people sure it's supposed to read 20bit/96Khz and 20bit/48Khz, and not 24bit/96Khz and 48Khz/16bit?

Audio sampling rates are not in kHz -- They are in samples per second, controlled by a sampling clock frequency.Discpad 10:32, 18 September 2007 (UTC)

It's not really clear by this article what ac97 is. As stated, it is a "Codec" which, in turn, is "signals being encoded/decoded ..." This clearly doesn't make sense. —Preceding unsigned comment added by (talk) 20:18, 12 November 2007 (UTC)

incorrect information about TI chip - tlv320aic23b does not support AC97[edit]

tlv320aic23 supports I2S but not AC97. I think this should be corrected. —Preceding unsigned comment added by Misha lodigin (talkcontribs) 10:38, 11 December 2007 (UTC)

Problems with "Problems" section[edit]


The "Problems" section is misleading. Under "Audio Settings," the article reads:

"Many people are not aware of this program[4], and once pointed to this program, find that an unwanted sound effect was set active.[5]. Various versions of this program exist, for configuring the audio settings including the input and output connector configuration."

Not all AC'97 compatible drivers provide this option. With the Microsoft Windows shipped Intel Audio Driver, no such program exists. The Realtek drivers install this Control Panel applet. Thus, the configuration utility is not "shipped for Microsoft operating systems" -- you have to download it from the Web. In fact, reading the cited document indicates that a provided setup utility configures and installs the configuration utility.

"Many people are not aware of this program[4], and once pointed to this program, find that an unwanted sound effect was set active."

This is a globalization, and it is false. Two instances were indicated in a forum, but this doesn't imply that many people are unaware of the program. In fact, *many people don't have this program at all*. More systems use a more generic driver than the Realtek provided one.

The "Problems" section is garbage. It links to the PC99 color-coding scheme, which explicitly states that blue is for unamplified line-in signals and states that blue is for headphone outputs. Then states some odd problem and cites a Yahoo! Answers thread as evidence. Most of the other problems are cited from various forums and are not evidence that a problem is widespread. I'm removing the "Problems" section as it's obviously incorrect, isolated to a few incidents and not particularly noteworthy.Kakomu (talk) 04:28, 15 April 2009 (UTC)


does anybody have the drivers? plz post it here thx —Preceding unsigned comment added by (talk) 19:21, 17 December 2008 (UTC)

Inaccurate statement[edit]

"Since AC-Link is a fixed-frequency link, all sample rate conversion should be performed in the DC97 (controller) or in the software driver." This is not correct. Read section of the spec linked below. AC97 supports variable rate data on the fixed speed link via "slot request" feedback. Jonsmirl (talk) 21:32, 28 April 2009 (UTC)
