ASUS M5A99FX Pro R2.0 Realtek Sound Problem

I'm having an issue with a build I have been doing with an ASUS M5A99FX Pro motherboard, with an AMD Phenom 965, 8 GB of Kingston RAM, and SLI Geforce 460s. When initially setting up windows on the drive, and first installing the sound drivers, they worked. After powering back down, adding the second graphics card, and hooking up the side panel fan to close it up, when Windows 7 came back up, the sound was gone. In the Sounds menu, the Speakers read "Not Plugged In" and the only options for sound are Digital Optical Output.

I've noticed a few similar threads all over the internet about this, but I have found very few "resolutions" aside from "Switched to another board" or "Bought a sound card." The latter isn't much of an option as the two graphics cards cover the PCI lanes, and I'd like to avoid having to bring it back if I don't have to. Does anyone have any experience solving this issue? I have tried everything except formatting again and starting from scratch.

Also - several suggested solutions say to "disable front panel detection" using the folder icon on the Audio controller. No such option exists on the version of Realtek that I installed. Any other suggestions are more than welcome, I would really appreciate it.

  1. Are you using the Windows driver for the audio or the Realtek driver on the MB disk?
  2. Initially used the driver that was on the disk. After the restart where it stopped working, I sought the latest driver from ASUS' homepage. Installing that did not help. I cannot seem to 'uninstall" the driver without Windows immediately attempting to replace them with it's own, and then I end up with about 6 different digital devices in my Sounds menu for some reason.
  3. Hmmm... yes, Win7 will always install its audio driver when it doesn't see one already installed. I'm not sure why you would have so many "digital devices" in Windows/Sound, tho. Modern gfx cards also have a sound chip in them. Not sure if the older GTX 460s do as well. If so, that may be where the other devices are coming from.

    But that doesn't solve your initial problem. Assuming the on-board Realtek chip didn't suddenly go bad, try uninstalling all the sound drivers one more time. Then run Driver Sweeper from Safe Mode (tap F8 @ boot). Have it locate and remove any remnants of any sound drivers it finds. Then re-boot and see if the Win7 sound driver it loads works properly.

    Before doing anything, however... it may be wise to try different speakers, cable, etc to be sure it isn't a problem outside the PC. Try your headphones on the rear jack. Try your speakers on the front jack.

    Both 460s have one HDMI port, so I believe you could be right on that count.

    Tried both of these before posting here, though I appreciate you bringing it up. Plugging anything in, rear panel or front panel, doesn't show as "Plugged in" and the Realtek software doesn't show a popup indicating it has detected a new device (and yes, the option in the software is checked to pop up on new devices). I hadn't thought of using Drive Sweeper, I will give that a shot for sure when I get home from work today. Thanks for that suggestion clutchc. I will update with my progress this evening.
  5. No luck with the Driver Sweeper. It still doesn't work after reboot :\
  6. Best answer
    Is it possible the front audio jack hasn't returned its contact to 'normal' after removing the headphones the last time? The audio system thinks there's still a pair of headphones plugged in? Try removing the FP audio connector from the MB and re-boot.

    In lieu of that, does it work if you remove the 2nd card again? Or the side panel fan? (???)

    Is there a possibility that you have something under the MB grounding out/shorting out the solder traces? Like an extra standoff that wasn't needed.

    I'm groping at straws here, but it sure sounds like you need to RMA the MB.
  7. Tried removing the front panel connector, didn't seem to make a difference. Tried removing the second card, and side panel fan. None of those changed any behavior :\

    There are a few extra of the metal/brass/whatever material they are stands that the mobo sits on that aren't secured with screws. I've never had an issue with those causing shorts before, but I suppose I could give that a shot. Is it often that unscrewed stands can cause a short?

    I might have to return it. Luckily, I bought it retail, so hopefully I can just exchange it, but I wanted to rule everything out if possible first since the store is 30-40 mins away.

    If your case is of the design that has the standoffs as an integral part of the MB backplate (i.e. stamped), then no. That wouldn't be an issue. But most cases have discrete standoffs that have to be screwed into the MB backplate in the location of the MB mtg. holes. Sometimes, not all of them will be needed. As a result, sometimes a builder will add one that doesn't belong. That causes it to be under the MB where there is no hole possibly shorting/grounding out a trace.
  9. I have extra metal standoffs screwed to the MB mtg. holes, but they are lined up with holes on the motherboard. The metal pegs came with the case, I just didn't apply screws to all of them, so no, none of them are pressing against a part of the board where there is no hole to screw into the standoff.

    Ended up having to bring the board back to the retailer. We switched it out for an MSI 990FXA-GD80, and it seems to be going strong. Thanks for all your help clutch.
  11. Glad to hear your problem is resolved. Happy gaming.

    I have FX 9370 with Asus Sabertooth R 2.0 and my icon disappeared from my task bar running windows 8.1 and my 7.1 surround sound became 3.1 lol Well I deleted all realtek off my system , ran ccleaner and becarful which one you download because theres been a lot of 3rd party downloads but the thing that fixed me is that I downloaded and installed the realtek audio manager , the internet controller and the drivers and finally I got my stuff back but do a clean install make sure theres no remainder of old drivers on your pc that's what screwed mine up , anything realtek delete , wipe it from pc and re install , its what I was told to do and it worked :)

    I also have a similar ASUS M5A99FX Pro R2.0 motherboard. I tried using the Realtek high definition audio drivers that came with the motherboard disk and also went to the Asus website and downloaded the most recent drivers to no avail. The solution was found within Internet options/advanced tab/under security place a checkmark in the entry allow software to run or install even if the signature is invalid.... Remove the checkmark from check for signatures on downloaded programs. After this the Realtek high definition audio drivers were able to install correctly. Why on earth Microsoft would place such necessary controls inside of Internet options is beside me. Also in the Realtek high definition audio manager you will find much-needed controls along the left side of the manager. One is a gear for device advanced settings. I switched playback device to make front and rear output devices to two different audio stream simultaneously I also switched the second option to separate all input jacks as independent audio output devices. I realize this is a little late to help you but may help some of the others in search of the answer.

    It's really helpful to see someone with a real solution to this! This has been an issue with my mobo since I first bought it, but I was too lazy to take it out of the PC and return it in time.

    So I did what you said and checked and unchecked those boxes in Internet Options and then I just reinstalled the Realtex drivers. It doesn't seem to have solved my issue however. I'm still not getting any audio out of my audio jack. I also still have like 6 mystery digital audio devices in the playback device manager. Any other advice you could offer?

    Make sure you install Flash in internet explorer x64 ......The Plugin for Firefox and or Chrome are not the same as Internet explorer x64 and you need this. This is the way I do it.....go to a site that uses flash like http://vaughnlive.tv/ using Internet Explorer, it will tell you you need flash and direct you to download the latest version from Adobe .....SORRY FOR THE PLUG GUYS BUT IS THE MOST FLASH DEPENDENT SITE I KNOW OF, download and install Adobe Flash.... You may want to disable any antivirus and firewall program after installing Flash. Rerun the Realtek high definition audio manager install software .....allow it to remove the current version, reboot then install the manager again..... In the Realtek high definition audio manager on the left side on the manager you will see a gear . Hard to see.....mouse over it will say Device Advance Settings, click on the gear when this opens switch both options.....option one switch to Make front and rear device outputs device two separate audio streams simultaneously. Switch second option to Separate all input jacks as independent devices. once this is done unplug any speakers, microphone or headset plunged in and plug them back in one at a time the manager will pop up and ask what this is, audio playback, microphone or headset....Front panel is not effected by this, but it will trigger the auto detect on rear jacks. Hope this helps reply so others will see the problem solved.
