Hd Audio Cable On Motherboard
Michael Rosiles
I'm currently setting up a older system in a new case (i'll be upgrading it in stages, and the old parts then go back into the old case ;p), and i'm having a bit of confusion over which cable to use, and what the difference is.
The cable looks somewhat like this , with the AC 97 connector attached to the HD audio connector. They both appear to have the same kind of connector (right down to the 'key' - the space where there's no pin and its filled up), apparently the same colour codes at close inspection and so on.
What's the difference between these cables, and when do i know what to use? In my case the sound chip is a ALC888 but i'm more interested in a generic, all purpose answer, rather than one specific to this. The header on the system itself is marked 'Audio'.
The correct one to use depends on your case. Those cables are typically used to connect front panel headphone/microphone ports. While the connectors may look identical, the pinouts are different and not really interchangeable. The matching connector on your case should be labelled accordingly, I know mine is labelled HD Audio.
Some sources indicate that it is/may be necessary to switch audio output modes in the BIOS configuration or with a jumper. It is recommended that you look at your motherboard manual. My own motherboard (MSI P67A-C45) manual just says it's compliant with the Intel Front Panel I/O Connectivity Design Guide, not all that much information. Dell manuals describe it as front audio (F_AUDIO) and don't indicate any such jumper, and only describe the BIOS option Onboard Audio Controller as Enabled or Disabled (Enabled by default).
On AC97 audio to the rear audio output was looped by the front audio output and plugging in a device to the front panel audio output would electrically disconnect the rear audio output from the audio source. If you wanted to use an AC97 motherboard without front panel audio it was nessacery to put jumpers on the audio header to make the rear audio output work.
On HDA audio to the front and rear outputs comes from seperate outputs on the audio codec. The pins that were previously used to loop back audio from the front are repurposed as connector-detect pins. It is up to software whether to disable the rear panel audio output when a connector is plugged into the front panel output.
If you plug an AC97 front panel into a HDA motherboard then plugin detection will not work correctly, it may detect devices as not present when they are present and vice-versa and the exact results may depend on what audio is playing. On some motherboards it may be possible to disable the plug-in detection so they can work better (though still not perfectly) with an AC97 front panel.
Your particular front panel looks to me like it is primerally designed for HD audio motherboards but with a hack to give limited support for AC97 boards. There are loops of wire on the AC97 connectors which will make the rear output work but it won't be switched by the front panel connectors like it would be with a proper AC97 front panel.
I'm not sure of the exact different (I assume that HD audio will gives better audio quality) but I'll always go for HD audio if the mainboard has it, if the mainboard only has AC97 then I'll use AC97 connector.
I have completed a modification to my AC97 female plug, by fiting a (Pin/socket) to socket 4 position for the 1K resistor to ground, and fitting a two pole switch to the front panel Cutting the two FP return wires at the Jack sockets and connecting them to the contacks of the switch.The FP wires are left connected to pins 6 & 10 at the plug. Provided a 5 volt DC cable to the poles on the switch from the motherboard. SEE PDF here.,,
AC97 cables usually have an empty socket in pin location 4. On the other hand HD audio cables have a wire and terminal connecttor lurking there, waiting silently in that cold dark hole poised and ready for the time when a naive unsuspecting pin 4 (who isn't even old enough to leave his motherboard) slips into the High Definition Audio clutches of that extra wire.. .
My motherboard is Gigabyte GA-945PL-S3. So due cleanning I had to disconnect front audio panel wires. Then I installed Windows 7 on a new hard drive. But now I don't know how to plug the wires back. Well I plugged how I remember (hope didn't damage it) but Realtek HD Audio Manager can't detect speakers nor microphone at front panel, everything seems to be fine on back panel. This is what manual show:
My motherboard is a Gigabyte GA-H87-HD3 and I was having the same problem of Realtek HD Audio Manager not detecting speakers in the front panel. After trying all kinds of solutions and reading the MB's manual dozens of times, I found out it was simply a matter of checking a checkbox!
Some front panel audio cables are bundled together so it is not that hard to plug in them correctly, but in many cases your audio cable's plugs are fully separated from each other like in the following picture:
Make sure the latest sound drivers are fully installed for your operating system (download the drivers from the manufacturer's website, do not use the built-ins). Then check the settings to make sure it detects the front headphone being plugged in.
What happed here is you must have mistakenly put the wires back incorrectly or forgot to attach the sensor detection wire it is needed so that motherboard checks if you have connected a headphone or mic or not,
From the image you have given it looks like pins 6 and 10 when you ground these pins computer thinks you connected a jack, 6 should be mic and 10 should be headphone best way to check is using a multimeter with continuity test mode these wires will get shorted to ground when the respective jack is connected.
Your motherboard (no matter its size) provides numerous different connectors and sockets, all of which have a singular purpose: to help you connect a myriad of devices and peripherals to your computer.
Most enclosures have a microphone/3.5mm headphone jack at the front, right next to the USB ports and the Reset and Power buttons. You can make these audio jacks work by plugging the AAFP connector into the motherboard.
Your motherboard should have six rear audio connections. These are color-coded, and you must plug the connectors in the correct ports to get the best audio experience from your front, back, and side speakers.

Okay so i am replacing the left speaker in my CEO's laptop but the audio cable does not remove. I have replaced speakers and other internal hardware in desktops & laptops for years with no problem. It does not look like it is melted on but it does not come off like others i have replaced before. I even checked out HP videos on replacing the speaker, but it does not come out the way it is shown in the video. I used a magnifier glass and looking at the replacement, it does look like there is a catch on the top middle of the audio cable plug that probably holds it in place, but there is no way to get to that since the connector is fully covered. Has anyone run across this issue, and if so, what did you try? Thank you ahead of time!
Got the cable out finally. It does look like it was melted in there (sit right beside the batter). Hopeully the connector on the board is not bad and it is the speaker itself, or this was all for nothing.
That being said, is there any kind of TaskTray icon you can see that is associated with your Audio System (configuration)? If so, is there a way you can disable or uninstall it for the time being to see if the hangs in Rhino go away?
The Nahimic is something that seems to be connected to the realtek driver on my motherboard. I found the device called NH3 on my computer device manager and uninstalled it. Tried to open rhino again after restarting my system.
OK, one thing you can try is to make a new user and see if things handles differently there. I had some issues with my windows10 a few years ago and before I did a full reinstall I checked and got confirmed that a new user did not have the issues I had. (So it might be worth as a shot in the dark, to check at least, while you wait for a fix )
Good luck!
Now I have not tried my system fully after this, I want to see if my audio still works and all the units that are connected with the nvidia card. I also have not tried the application fully, but so far there are no issues. ( I have tried with different views and modes, rendered, shaded, raytraced and wireframe all work.
I found my way here because i was troubleshooting a similar issue where Katana (all versions after the hydra viewport was introduced) would lock up when moving the Hydra viewer over to a second monitor.
You are now searching for the correct audio port connections for them on your computer. While they can be connected directly to a monitor, having the inbuilt ones on the motherboard is the best solution.
There are various sorts of audio port , and contemporary circuit boards can contain six or more of them. This, however, is dependent on the model, therefore you may find less on yours. Similarly, most laptop motherboards have only one audio port that may serve as input as well as output.
The motherboard of a machine has an audio port. This port is used to connect audio devices like speakers, microphones, and home theater systems. The audio port is only functional when a device is connected through an electrical connection or cable. Audio port are required when using Bluetooth technology.
The audio port of a desktop computer are located on the front and back sides of the CPU. However, depending on the manufacturer, the audio port will be situated on either the left or right side of the keypad. There are several techniques to determine the motherboard type on the machine you are using.
