First i'll tell you how the problem began. I was plugging in an extra hard drive into one of my CD drives slot and while doing so I had to remove my ram chips and my CPU heat sink and fan. In doing so I had problems with my CPU but I fixed them my main problem was when I plugged my ram chip back into the computer I let of a static discharge and fried one of my ram chips! Now all of the sudden after that I get absolutely no sound from my integrated sound chip. My brother who is really good with computers and a worker at a computer store at Compu-silv in Brockville Ontario told me it had to do with a driver or my bios. So I checked both and they were fine. I downloaded the newest driver for my Realtek chip (version A404) and nothing changed! My other problem is I have Xp and Vista on my computer and both OS'S sound stopped so I highly dought it's the driver. Anyways my computer knows the driver is installed and yes I made sure the fricken thing was properly plugged in because I ain't that stupid. I even checked windows Vista and showed that my audio device was putting out a signal. So my chip is working i'm just getting no sound from it. I have tried multiple speakers so it ain't the speakers. I f anyone can help please reply to my message.
This worked on a Fujitsu Amilo PC after a new DVD Drive installed and running Vista Home premium 32 bit. No sound was coming out of the same pair of speakers used before the repair but all the system checks showed that Realtek was working. So I contacted the repair company and this was the fix:
Open Realtek manager then plug your speaker lead into the front headphone socket and your speakers should start working. Obviously you need a CD playing, and at the same time an info box will pop up. This box will show a list of line in/line outs and have a tick against the Headphone entry. This proves that Realtek is working. If it's still not working then I can't help you, but if it is:
Unplug the speaker lead and plug into the the Green audio connection at the rear. Your speakers will probably not work but this will bring up the info box again and there will be a tick against the Rear Speaker entry. Untick and then tick the Front Speaker entry, click OK, and your speakers should now work.
This confusing (to me) setup is because Realtek is configured for surround sound but getting the information seems difficult if you don't use and so are not used to surround sound. Obviously this has only been used for a pair of speakers but if you are having similar problems with surround sound this might help.
I had this exact same problem with my HP computer and Realtek HD sound card/Audio Manager.
I'm running Vista 32 Home Premium with all the latest drivers. I'd installed a new HDD and also RAM which I think somehow triggered the problem. The device thought it was working correctly, the volume/equalizer was moving up and down but no sound was coming out of the headphone jack or rear analogue output.
In the Realtek HD Audio Manager console, the Digital Output was set to default which explains why no sound was coming out of the jack sockets!! I clicked on the 'speaker output' tab and then clicked 'set as default' and now it's working perfectly again.
Simple enough to fix but I have no idea what made it switch to digital in the first place!?!
find out what motherboard you have easy way is to download a program called everest that will tell you the mother board manufacturer that way you can check the bios revision. anymore you run a flash on windows instead of dos. manufacturer will have chipset drivers as well to update
0o There is loads of known problems with realtek audio some people have problems others do not mine I have to use the black audio port all others give no sound :/ had a look around seems problems are common so it may just be the hardware is messed up not anything to do with software seems most the time it is so i've had two with the hardware shot so i've learnt my lesson XD bought myself a nice sound card :p so remember next time don't buy a motherboard with realtek hardware my school had to replace most there computers cause they did that XD hope this helps :) - I think it's really to do with the realtek audio chip but I don't have an idea on how to fix them :/
it appears ASUS virtual video capture device driver, high definition audio device, realtek high definition audio. And it's everything Ok.
I went to Bios and I disable the sound and sound works when I disable it. but when I shut it down and turn it on again the sound's gone.
have you tried taking the C-mos battery away from the motherboard and switching the jumper pin for 30 secs then put it back, then place battery back into its slot on the mother board and boot system. I did that and this fixed every problem for me. windows found all the "new hardware" (it wasnt new just messed up like yours) and then let me install all the drivers. now my AC-97 is xplodin with noise again and I can tweak my graphics and so on....
