No sound from ASUS P6T

January 25, 2010 at 10:50:13
Specs: windows 7 (64bit)
I have an issue i can not resolve. I just built a new computer, specs- i7920 intel, asus p6t(not v2 just p6t) motherboard, 6gb corsair mem, nvidia 9500gt 512mb graphics card. The m/b audio device is a realtek alc1200. The issue i am running into is that i get no sound coming or very faint sound, from the motherboard when i hook up my speakers on the green jack on the motherboard. I have to turn up the sound all the way on a pretty powerful home theater reciever to hear a very slight, faint sound. I recently installed windows 7 (64bit) as my os. I downloaded the latest drivers from the asus website (realtek drivers), they are installed with no problem, they show up in the device manager and are enabled. I also know the speakers are good as i tested them. I am pretty much stuck. I also made sure everything is enabled in bios. help, what should i try next?

I'm assuming this is the same as in Vista...
RIGHT click on the speaker icon in your taskbar lower right.
(if that's not there your sound drivers have probably not been installed properly)
Click on Volume Mixer.
That shows you the master volumes. Increase them if you need to. Make sure they're not Muted (muted = a red symbol beside the speaker icon at the bottom)

If you still have problems...
RIGHT click on the speaker icon in your taskbar lower right.
Select Playback devices, or Recording Devices
The present volume setting is shown in bar graph form on the right. If you want to change the volumes, highlight one of them, click on Properties, select Levels


Control Panel - Realtek whatever
(if that's not there your sound drivers have probably not been installed properly)
You can adjust the volumes for different types of sound there.

NOTE that the mic playback is Muted by default - that's normal - it's unmuted automatically when you use a program that can use a mic, and muted again when you exit the program.

The onboard sound output on modern mboards has to be amplified. If the sound is a reasonable volume with regular amplified speakers for computers, how well that works varies depending on which speakers you use, there's nothing wrong with your onboard sound. If you have more than one type of way of inputting sound from the green port to the home theatre system at the latter, try another way.
If that doesn't help, you need
- a preamp between the green port and the home theatre system.
OR - some sound card models you install in a slot have an amplifier (preamp) built in - get and install that instead of using the onboard sound.

You can install the software for and have more than one sound chipset available to Windows 95 and up, if they are different, but only one can be used at a time. The one the drivers/software was installed for last becomes the default one for the Windows sound, but that can be changed in Control Panel

The correct way to install the sound chipset software and associated programs (sound "drivers" software almost always has associated programs installed along with the drivers) is.....

- if the drivers/software is not automatically installed by the operating system, which is the usual case....

- the proper sound software is on the CD that came with the mboard if you have a generic system, or in the downloads for your model on the brand name system's or mboard manufacturer's web site in the downloads for your model. If you randomly get sound "drivers" from the web, there are many different possible Realtek (and other brands) of sound chipsets - the download is likely to not work or not work properly for your sound chipset.
If you can't find drivers for your operating system, more likely if you have an older system or mboard ( Vista drivers often work for Windows 7), you can get generic drivers from the makers of most sound chipset's web sites, however make sure you get the ones for your particular sound chipset - which chipset model it is is printed on the sound chip on the mboard in a generic or brand name system, and/or specified somewhere in the specs for the mboard or the brand name system model.

- DO NOT install the "drivers" for the sound while booting the computer when Windiows detects the sound device while booting - CANCEL that, and continue on to the desktop.
(If you DO install them while booting, at least some features of the sound and associated software will probably NOT work properly. If you have already done that, un-install the sound "drivers" BEFORE you try installing the same or other "drivers". )
Install the proper sound "drivers" from a CD, or install them by using the proper download. Some downloads auto extract and then run the Setup, some downloads auto extract and then DO NOT run the Setup - you have to go to where the files were extracted and run Setup, and some downloads you have to extract the files and then go to where the files were extracted and run Setup.

the sound is amplified, the driver is installed, and its not muted through any channel/program/sys setting that would mute it. i still can not figure out why i dont have sound.

I agree with kuwese, why would you build a Core i7 system with 6GB RAM, then install a crappy 9500GT? Tubes pretty much covered the rest.

Besides the driver, did you install the Realtek HD Audio Control Panel?
