It's a sound adapter, but it is NOT a CARD unless it plugs into a slot in the mboard and can be removed.

We have no idea which sound adapter you have going by the info you have provided so far.

In most cases, if your sound adapter is not ancient (made before the mid 1990's) , it supports full duplex sound.

If it's built into the mboard, we need to know your model.
If it's a CARD that installs in a mboard slot, we need to know the make and model of sound card you have. E.g. Creative / Soundblaster cards have a SBxxxx or CTxxxx model number on the card.
If it's a USB connected sound adapter, we need to know the make and model.

Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.
The specific model of a brand name system is shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

The model is often also displayed on a logo (graphical) screen early in the boot, but it's often not as specific as the specific model number.

For Dell computers, they have a Service Tag number - the specific model can be determined by using that on their site, or can often be determined there automatically by you downloading some software. The Service Tag number should be on a label on the outside of the case, probably on the bottom on a laptop, on the back on a desktop, and is often also shown in the bios Setup.

All chips or chipsets that that produce sound on a computer are sound adapters, whether they're on a CARD that installs in a mboard slot or not.

If the card's chip or chipset supports 4 channels, it definitely supports full duplex sound.

I see you posted about this elsewhere.

"Problem for Compaq Audio card Sound Card

INTEX SOUND CARD YAMAHA-4CH YAMAHA JAPAN XG YMF740B-Y 9842 GBIP I have this Sound Card but when Audio wizard runs it says you don't have full-duplex sound card. Is it true or it may need update driver? Thanks "


You have probably installed the wrong software, or you installed the right software the wrong way.

Apparently this card came installed in some Compaq computer models. Is that what you have it in ?
If so, the HP web site should have the proper software for the card's chip or chipset in the downloads for the specific Compaq model.

If not, there are many "hits" on the web for "drivers" for this card, but at least the YMF740B in YMF740B-Y must be the same in the description. Y may be merely a revision of the chip.

I'm saying sound software, not sound drivers, because the "drivers" downloads for sound adapters ALWAYS include other software that must be installed properly along with the actual sound drivers.

Unless the instructions for installing a device tell you otherwise.......
(this ALWAYS applies to sound adapters...)
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.

The same applies no matter when Windows finds New Hardware !

If you DID install drivers that way,

(The following also applies if you want to re-install the sound software)

- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting.

- go to Device Manager.
(e.g. RIGHT click on My Computer - Properties - Hardware - Device Manager)
If the sound adapter is still listed, RIGHT click on it and Un-install it.
If that was there, and you un-installed it, Reboot at least once.
DO NOT install drivers while booting.

Install the sound software properly by running the proper download you got from the web, or if you have the CD that came with the sound card, or the CD that came with the computer that has the Drivers on it, run the sound software installation from the installation program on that.

It's also a very good idea to DISABLE any resident modules of anti-malware or third party firewall programs that are installed on your computer (a part that runs all the time in the background looking for suspicious activity ) BEFORE you install the sound software, otherwise the resident module(s) of those programs may interfere and prevent the software from being installed properly.

You can often find the proper sound software even if you're not sure which HP or Compaq model it came in.

When the sound card is or was originally in a Compaq or HP computer, it probably has a stuck on label on it that has the HP or Compaq part number on it.
If so, you can use that part number to search with here,

and usually you'll get a list of the HP or Compaq models the card was used in.

Then you can use the computer model or Product number of the computer model to search for the proper software downloads that include the software for the sound adapter.
