|The onboard sound must be enabled in the mboard's bios Setup. It is by default, and when you load bios defaults, or when clear the cmos and move the jumper back, or when you remove the cmos battery for a short while then replace it. |
You must plug in amplified speakers into most onboard sound, and the speakers must be powered on, and the volume on the speakers must be set high enough for you to hear something . If you have a single pair if speakers, the 1/8" jack you plug them into is usually green. If you have more than two speakers, you may need to use a program supplied with the sound drivers to set up the use of other jacks for some of the speakers, or if that program is already installed, something may pop up and ask you what you are connecting to other than the green jack when you plug something into the jack. Sometimes an icon for that setting program is in Control Panel after you install the sound software.
You should always install the main chipset drivers before you install other drivers, otherwise the software for other devices may not install, properly.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
When an installation of drivers and associated programs (the sound drivers download usually includes associated programs) fails to yield you sound, if you can't find any reason for that, you must un-install any listing for that in Add/Remove Programs BEFORE you attempt to install that or other sound driver related software. If you do not do that, the previously installed software is likely to interfere with the proper installaion of the software you're installing, especially if it's made by the same chipset maker.
If there is anything unknown to do with the sound in Device Manager after un-installing entries in Add/Remove programs and re-booting, Remove those entries in Device Manager before installing the sound software. If they appear again after rebooting, you may need to Remove them again, and NOT reboot, install the sound software, then reboot.
DO NOT install the sound drivers while booting the computer. (This also applies to lots of other devices.)
When you boot the computer and Windows detects the sound device, and you have it search for drivers and it doesn't find any, and it asks you to point to the location of drivers, if you DO load thedrivers that way, in most cases at least somefeatures of your sound will probably not work properly, if you get any soundat all. CANCEL that, and let thedesktop screen load, then run the proper installotion download or sound software installation from your mboard CD.
Sound chipset makers make lots of versions of sound chipsets. You must install the right drivers and associated software for whatever chipset. The sound software that came with the mboard on it's CD, the sound software for your mboard model, and the sound software that can be downloaded from the chipset makers web site for your specific chipset model is the correct version, but a version you get randomly on the web may not work properly, or at all.
NOTE that some mboard models have TWO possible onboard sound chipsets - e.g. a simpler AC97 compatible codec one, which usually has only 3 1/8" jacks, or an optional more sophisticated sound chipset, which usually has more than three 1/8" jacks. A mboard CD or the downloads for your model on a mboard manufacturer's web site may have software for both types. See your mboard manual. Check the model numbers of the sound chipset on your mboard.
If you have a sound card (in a slot) installled as well as having the onboard sound, Windows supports you installing support for more than one sound chipset, but only one can be used by Windows at any one time. Whatever software you installed last for whatever sound chipset becomes the default sound device used.
You can change the default sound device in Control Panel - Sounds and Audio Devices - Audio
