Had my motherboard die on my Dell Vostro 400 last fall, so I basically rebuilt my pc (new psu, motherboard, case) kept the chip (Intel Core2Quad 6600 2.4mhz) hard drive and disk drives along with the video card(Nvidia GeForce 8600 GT). Had my normal pc guy put the machine together and he installed a "Teaching" copy of Windows 7 Pro. Everything was great til my hard drive crapped out a couple months ago, got a new one and had him install and pull the back up off my external hd and everything was back to normal.
Last month when Microsoft came out with the Service Pack for Win 7, I installed the update and they busted me for an illegal copy of Win 7. Basically froze me up with a nasty black screen and a message saying that my copy wasnt authentic. So I broke down and bought the family pack upgrade for Win 7 Home Premium. I had to install Vista on the pc to get the upgrade to run, did that then installed Win 7 Home Prem with no problems. Except that now i have no sound.
Before my sound was running off of Realtek and all of my jacks worked properly and i had no sound issues. Now it is telling me that I'm running the Microsoft HD Audio Device (which comes on the ASRock P43DE motherboard that im using) and i only have access to a Rear Panel Optical Jack which I cant seem to find.
I have tried updating my drivers, have played with every jack on the pc and cannot seem to find the problem. When i try and troubleshoot it tells me everything is working properly. Any ideas or thoughts would be greatly appreciated.

According to the Asrock website your motherboard uses the VIA high definition audio driver ver:v7500F_HDMI for the win 7 OS. The reaktek drivers are for the LAN(Network).

I would also redownload the inf drivers and install them as it maybe that you need the ich 10 chipset drivers for the sound to work.

Thank you for the help. Downloaded and Re-Installed both of the drivers, and still having the same results. I think the real problem is that my pc isnt recognizing my speakers at all. I have looked at some stuff, where ppl have had the same or a similar problem and they found that they had disabled their speakers, they were able to enable them again in the control panel>sound , by looking up the disabled devices. I dont even have my speakers showing up at all. I know my speakers are working because i tested them with my wife's laptop. So i think I'm back to either the pc wont recognize the audio jacks themselves or my speakers.

Is it possible if the sound is built onboard that it has been disabled in the bios?
OK then lets make sure the audio is enabled in the bios.
Reboot the system and at the first post screen tap the Del key normally and it should get you into the BIOS
In there find either the Advanced, Onboard or Integrated Peripherals areas.
Using the keyboard arrow keys scroll down to the Audio entry and make sure it is Enabled and if not then look at the bottom of the screen it will tell you how to adjust or modify the values to Enable it.
When done make sure to click F10 to Save and Exit with the setting.
You will then be asked to click Y to Verify the Save and Exit
The system will now reboot with the new settings saved.
Let me know if this helps.

Tried that one the other day :) But i did just recheck all my bios settings to make sure i didnt see anything out of whack. The onboard audio is enabled and the Front side audio is on auto (the only other choice is disabled). I think Im losing my mind.

What about Device Manager is it showing any yellow exclamation marks?
Also check audio properties.
OK then I need to see what the Audio Properties show as your default audio device.
Go to Start and then to Control Panel
Right click on the Sound or Audio Devices and then click on Properties
At the top of the window click on Audio and what does it say for Default Audio Device?
Click on Playback and same information?

As soon as Sr comes back he can resule with everything.

Think i might have found a solution. Was looking up the realtek audio stuff and found an interesting link, not exactly my problem, but very similar.

Just downloaded the updated Realtek audio codecs, gonna restart and see what happens.

Still dont have any sound, but im wondering whether ill need to go back and disable the onboard audio in the bios after downloading the realtek codecs.

Sorry, i forgot to answer youre last question, the default device is listed as Digital Audio (S/PDIF)/ High Definition Audio Device / Default Device

The Realtek AC97 driver would have been a option with both SRX660 and myself if the issue could not be resolved using the other drivers.

Your audio is built on the motherboard isn't it or have you installed a add on card?

my new motherboard does have the audio built in, but i remember using the realtek interface just recently. I dont think i have an addon card and I'm trying to remember back to last year to figure out why i was using the realtek interface, even though it seemed a lot better than what i have now.

As SRX6660 stated earlier it looks like the Realtek driver is for the Lan and not the Audio.
Check speaker connection to back of system
Check volume control in windows by doing the following:
Go to Start and The Run
Type in sndvol32.exe and press Enter
Make sure Master Volume is not muted and turned up
Check Cd Player volume is not muted and turned up
