HD Audio can sense the presence of an audio dongle. The only thing i can recommend you at the moment is to run Windows Update to see if any drivers related to your mother board are found, if it does and you are lucky Realtek High Definition Audio Driver should show up as well,then install them. I don’t understand why Realtek doesn’t provide same functionality at least. Like AC’97, HD Audio is a specification that defines the architecture, link frame format, and programming interfaces used by the controller on the PCI bus and by the codec on the other side of the link. From the drop down list under drivers only Win 7 x64 seems to be supported,i am not saying that Windows 8.

In the HDA design, when the plug is not inserted, the codec sends the audio directly to the speakers the audio does not go out to the front panel and then loop back to the speakers.

In AC’97, pins 2 and 4 are audio ground, but pin 4 is often disconnected. Click here to post a comment for this file on the message forum.

Went back to 2.

By using this site, you agree to the Terms of Use and Privacy Ajdio. Many motherboards with AC’97 audio need two jumpers to short the pins in case no front panel audio module is connected, so audio passes to the speakers.


Seems like that only thing for which second restart is required is running a control panel hidden in tray set up to launch at system start.

But this program may be run manually without problem and without second restart of course. OK just a question after you are finished installing Win 8. Not present, physical key.

Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way. Computer motherboards often provide a connector to bring microphone and headphone signals to the computer’s front panel. If I wanted to use this for Ventrillo, or Skype, or something, I would not want it recording Hz for simple voice crap. Like AC’97, HD Audio is a specification that defines the architecture, allc frame format, and programming interfaces used by the controller aza,ia the PCI bus and by the codec on the other side of the link.

Realtek has the best driver support. Since there azalka no drivers listed on MSI’s page for Widows Very good driver without a single problem so far. Info about the driver: R is still the best version on my rig.

If the headphones are not plugged in, the jack directs the audio to the return pins that are connected to the speakers. Consequently, an HDA motherboard would not detect the presence audioo an AC’97 dongle with a disconnected pin 4. An AC’97 dongle returns audio on pins 6 and 10 rather than a digital plug sensing signals. Otherwise he would have mentioned the wide range of X-Fi based cards. Depending on the distribution, linux doesn’t even require you to do anything at all – just turn on the system and sound works.


I guess it must be a beta or alpha of some kind. Microphone bias Audio, right, in biased, al. Audio, mono, in mic.

Same goes with display drivers etc! The Gigabyte board in my woman’s, is the same chip but intel based. A similar isolated switch is used to detect when a microphone has been plugged in.

Interesting but my card isn’t based on the chip that guy is talking about. Views Read Edit View history.

Realtek High Definition Audio drivers R2. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in. Intel High Definition Audio also called HD Audio or development codename Azalia is a specification for the audio sub-system of personal computers. Likewise, some modern enclosures have both an “AC’97” and an “HDA” plug at the end of the front-panel audio cable.
