Windows 7: Windows Update Breaks RealTek Audio

I did see something that has been happening since the beginning of the problem: the Sound window with the four tabs, Playback, Recording, Sounds, and Communications, never lists the headphones or microphone. That may be why the Realtek HD Audio Manager keeps dropping them and picking them back up again.

Intel motherboard sound troubleshooter

Hi. It might be worth a shot at running the sound troubleshooter for intel motherboards. It fixed issues with the Realtek drivers on my old machine. It should be able to detect what drivers are installed and update or install the correct drivers.

No joy. I couldn't find the "mixer" for the Realtek sound manager, which looks entirely different from the screenshot on the Intel troubleshooter page, but I did find the Speakers with test buttons, which produce no sound.

Note that I have noticed that the system Sound window does not pick up the headphones or microphone when they are plugged in, which may be why the Realtek HD Audio Manager keeps dropping them and picking them back up again. When I un-installed the Realtek drivers, Microsoft installed something on boot which *did* see my headphones and microphone - but no sound out the jacks.

Some quick info before i have time to look further

I see you nVidia graphics card has HD audio (it has an HDMI port) if that could suit your needs. But the HD device on nVidia is running the MS generic HD driver. Install the nVidia HD audio driver for your graphics card.

Everything looks OK when Realtek is installed. But I find it odd that when uninstalled, the Realtek devices disappear (don't seem to be detected). I'd still expect it to (probably) be able to run with the generic MS audio driver and be listed under Sound, video with a generic sounding name like "High Definition Audio Device" or you see a device under Other category with a yellow icon. With MS generic audio, we should still be able to hear sound when Realtek uninstalled. Will follow up later with instructions on we might "coerce" those chips to be found when Realtek uninstalled (so would then also be interesting to see how jacks work when no Realtek driver)

Sorry for double post, but here's an example of what I'm talking about using my own PC which has a webcam, onboard audio and addon nVidia graphics w/HDMI. When I uninstall the Soundmax driver the HD audio device is still detected and listed in DevMgr

It would be interesting to test the jacks when Realtek is uninstalled. But will have to follow up later

The speaker jack has no sound with the Microsoft driver, either. Neither does the headphone jack.

My speakers are truly ancient. I bought them off the shelf at Fry's in the L.A. area sometime in the late 1980's. They are Altec Lansing ACS51 Computer Speaker System "with Phantom Bass." They are the oldest component still in use. I did try them on my cell phone yesterday and they played a YouTube video about a Pontiac Fiero with a supercharged 383 cid (6.3 liter) V8, replete with exhaust sounds that fully exercised the "Phantom Bass." That cringe-worthy performance left no doubt about the performance of the speakers, although I do have my doubts as to the performance of the Fiero. But I have no way to use an HDMI output without constructing an all-new project. If my wife ever figures out that I can operate our TV with my computer, I am doomed; the TV is right through a wall and a simple feed-through would do it, probably with ordinary three-foot cables. The monitor is operated through a KVM switch that uses VGA connectors, and I use a DVI to VGA converter at the video card. I need the analog speaker jack output.

I suspect that the extra High Definition Audio Device is the HDMI output driver. There are four of them listed in the Sound window playback list, all marked not-plugged-in, along with Realtek digital output, electrical and optical, which have bar charts next to them. Speakers is checked and marked as Default, and when I run the speaker test the bar chart moves on the Speakers output but not on the digital outputs.

I just turned the speaker volume all the way up, which is enough gain to hear the electrical noise of the power supply ripple at a medium level, say, 50-60 dBa. It's a high whine punctuated by a busy modulation and other lower-frequency noise that seems to be vaguely in time with the blinking of the lights on my FIOS modem/router next to the right speaker. I can actually hear the speaker test sounds, very faintly, below the electrical noise!

Plugging in the headphone jack brings up the RealTek HD Audio Manager and a message window that tells me that I have plugged in a headphone. The electrical noise in the speakers doesn't change. And, the headphones don't appear as a Playback device, either. But I can no longer hear the speaker test sounds under the electrical noise. Unplugging the headphones, I get pop-ups from Windows and from the Audio Manager that it is unplugged, and once again I can hear, faintly, the speaker test sounds under the electrical noise.

This time I did NOT get the endless loop of the Audio Manager dropping the headphones and picking them up again.

Something is working in there. But the speaker jack output driver isn't enabled because all I can hear is the background noise from a highly amplified non-enabled output; at a reasonable volume setting it is inaudible. And, most of the time, the Audio Manager keeps dropping the headphones and picking them up again. And, the Sound window output devices do not pick up the headphones; with the Microsoft drivers the headphones are added to the list, even though no sound is output to the headphone jack, either.

At this point, i think is probably best and easiest to plan on using the new sound card you ordered.

That said, I have a theory. May or may not be true but seems to fit the scenarios you describe. The Realtek audio chip is probably flaking (could also be controller or HD Audio bus - but i'd guess the audio device)
> Windows talks to the audio controller
> The controller talks to the Realtek audio chip and,
> Your jacks connect to and are controlled by the realtek audio device

Your jacks appear when the Realtek chip is working and detected. When it falls "offline" Windows can no longer see them as the end-to-end comm path is broken.

Use DevManView to check. (You;ll need to monitor it and check for yourself in real-time).

Here's what to do/look for. Run DevManView. We only care about two columns: Device Instance ID and Connected.http://www.sevenforums.com/images/smilies/sleepy.gif

Device names can change. The constant that uniquely identifies each chip is Device Instance ID. Click the column header to sort by ID. Now scroll down to find IDs that start with HDAUDIO\.
  • ID of your Nvidia chip starts HDAUDIO\FUNC_01&VEN_10DE. You can ignore that one
  • ID of your Realtek audio starts HDAUDIO\FUNC_01&VEN_10EC. That's the only one we care about
Also note there's a Connected column to the right of ID

Windows can only see the jacks IF {the Realtek chip appears in DevManView} AND {Connected=Yes}

The jacks won't appear if either {the Realtek chip no longer appears in DevManView} OR {it's there but Connected=No}

As you watch the Realtek HDAUDIO ID, you'll need hit F5 to refresh the data to see any change when jacks appear and go

/EDIT/
p.s. When you uninstalled Realtek and rebooted, what you saw may have been Windows, re-detecting the audio chip and then install the generic audio driver (its only choice since Realtek was gone). But the jacks still fall online/offline as chip detection works/fails

well motorfingers; I do agree with what you mentioned as well; you should not need the driver for windows to detect the device; because as long as the device is plug n play; then yes windows should detect it and install a different form of driver per say; but one which wont give it full functionality; but enough function to at least give you some sort of indication that it is partially working. And yes the audio controller does play a part in this as well.

I too have a motherboard with realtek on-board audio; but I dont use the onboard audio; as i had a better sound setup with the sound blaster pci express titanium sound card i have in my system. So while yes i could have just gone with the onboard audo; why bother when the sound blaster is better imo.

The post office has the card now, according to the tracking. Last time they had a computer part in town, they shipped it to Cape May before delivering it, presumably for the view, and it arrived two days late, with the tracking scan "down the shore" deleted from the tracking record.

I have an appointment and will come back here in an hour or two and complete the checks with DevManView. I did use the DVD that came with the video card (Gigabyte GEForce 660) and got the NVIDIA sound driver. I have thee now, one from the Logitech C920 webcam with microphone, one for NVIDIA, and the RealTek. There is a fourth driver that I see in most people's screen shots that is not there. I do recall that before I re-installed Windows that there were four in my system too.

I've had the feeling for some time that it was the sound card hardware. It's full Azelia spec with all the exorbitant bandwidth and word length available, and my stop-gap sound card is not top-of-the-line. I'll look into RMA-ing my motherboard if we do come to that conclusion firmly enough to convince ASUS USA. IMHO, a bad ASUS motherboard is pretty rare, the recent demise of my aged DSGC-DW notwithstanding. It's probably a chip on the board somewhere. I would rather find that and change it than RMA the motherboard, if it is socketed.
