Audio Device Not Found / Listed In Device Manager

Aug 4, 2010

I had some trouble last night and today with getting rid of a virus. Now that it is gone, I am having sound problems (maybe related, maybe not). This morning, when I opened iTunes I got a message that there was no audio device detected. After trying several things, I rebooted. Magically, I could play music again. However, a short while later, I again got an error message telling me that there is no audio device found, even though it shows up in Device Manager as working properly. The problem goes away for a short time after I reboot, but returns. It is Realtek AC 97. Why won't my computer keep recognizing it? (It tried going to Realtek's site to download an update. It has updates for Windows 98, 95, etc., but not for XP. Or at least I couldn't find it.)

No Audio - Cannot Open Device

Nov 2, 2008

the audio on my computer has recently stopped. I am running an AMD 64 3000 with WINXP SP3, and have an Asus A8N-E MB using onboard audio. I have tried re-installing the nvidia nforce audio drivers, but they still do not appear in the device manager. Under sound, video, and game controllers in device manager, I have:

Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Logitech Microphone
Media Control Devices
MPU-410 Compatible MIDI Device
Standard Game Port
Video Codecs

In control panel under sounds and audio devices, it says I have no audio device, and that there are no playback devices. When I try to play a song in RealPlayer, it says "cannot open the audio device. Another application may be using it." Could an overheated chipset cause only the sound to malfunction? My chipset fan recently failed and I was running without it for a little while.

No Audio Device - Won't Play

Oct 2, 2009

I am using a Sony Vaio Model PCG- 7X2L and it won't play any sounds. There is no volume control on the task bar, so I went to Sounds and Audio Devices and it says there is no audio device. When lookng at the Device Manager, this is what is listed under Sound, video, and game controllers:

Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
Video Codecs

I don't see anything that says Realtek, SoundMax, or any other similar devices. What do I need to download in order to have sound play on my laptop?

LAN / Firewire / Modem Have Disappeared From Device Manager

May 4, 2005

This morning when I went to the computer, the screen was blank and the computer was running. There was no HD activity. The computer was not hibernating. Eventually I reset and the computer would not boot. I opened the case, removed the video card and was able to boot to XP Pro SP2. I had left the computer on overnight to render/burn a DVD with Sony Vegas.Once I got to the desktop, I found that networking was no longer functioning. None of my network connections appeared under "Network Connections". My onboard LAN (Realtek RTL8100) was no longer appearing in my device manager nor is my modem (not that I ever use it) or my firewire card. I don't know what else might be missing.I have a MSI MS-6533 Mainboard w/ Intel P4-1.6 GHz (Bought as barebones system).

Device Manager Is Blank / Sound Has Disappeared

Aug 23, 2007

There are a few things that contributed to the leadup to me losing my Device Manager and sound. First, about 3 weeks ago, I bought 2 sticks of Mushkin EM3200 DDR RAM (two 1GB sticks; 2GB total). Installed it, and it disagreed with my board in a big way (apparently it was the voltages or timings). I managed to get as far as "Verifying DMI Pool Data..." before I got one of two error messages: "NTLDR is missing. Press Ctrl+Alt+Del to restart." or "Windows failed to load because the System32 folder is corrupt or missing." In each case, I popped in my Windows XP disc and fixed the boot record from the recovery console (I did not restore the MBR), and it booted right in.

At the time, Windows booted up just fine, but lately I've been having some funky problems. I've got one SATA drive (partitioned into two) which is my boot drive and one IDE drive that I just use for storage. Sometimes, with my IDE drive plugged in on boot, I can't get Windows to load by any means. Sometimes it boots just fine. When it boots fine, and I go into "My Computer" (either via the Start Menu or the icon on the desktop) it takes about 20-30 seconds to actually display anything (I get either the flashlight-over-folder animation or it just doesn't load). With my IDE drive unplugged, I get no such issues.

As well, the first couple of times I restored the boot record, I had no issues with sound at all. Then suddenly Windows started saying I had no sound device (my volume icon had disappeared, and the "Sounds and Audio Devices" menu in the Control Panel showed no output/playback device) although I clearly do have one. The weird thing is, I still got sound. Then I updated my sound card drivers (it's onboard sound; Realtek AC'97, pretty standard fare) and lost sound completely. All I get now is motherboard/PC speaker beeps. So I attempted to check the Device Manager to see if maybe there was just a device conflict. I say attempted because my Device Manager was completely blank. And I mean completely. All it showed was the title bar, menu buttons, and a white page. Nothing else. Zip.Just ran out to work and got an Audigy for $30 thinking it may just have been my onboard sound kicking the bucket. Installed it, booted up and tried to install the drivers. The driver installation program detected no Audigy in my machine (and I thought it wouldn't because Windows didn't pop up with the little "Found New Hardware Wizard" when I booted).

Audio Device Missing Driver

Jul 24, 2008

After going through many trials, tribulations, and attempts to fix my computer, i was left with only one option, to fully restore it back to factory settings. i thought this would cleanse all of my problems. now i have no sound. i have tried running services.msc and windows audio is correctly enabled. it is likely to be a missing sound driver, but i have no clue how to determine where i can get this said driver. i think it is important to note that it appears that none of my usb ports in the front or back of my computer are active.

Configuring Usb Audio Device As Spdif

Dec 3, 2009

I have a USB to SPDIF converter that is supposed to support 5.1 surround. I can hear stereo sound, but not 5.1 surround. I know there are many free tools that enable passthrough on spdif so the receiver does the dedcoding instead of the PC. However windows XP doesn't see the USB audio device as SPDIF is there a way to configure the USB audio device as SPDIF without drivers?

Audio Device Fails To Start Repeatedly

Jan 5, 2007

I am still having a recurring problem with my Realtek Audio Device. This is not a new installation and no other new hardware has been installed on the computer (Win Xp Home, SP2). No conflicts are shown. I fear that some files may have become corrupted but this is one behaviour which constantly recurs - maybe someone has a fix or knows what files I need to replace.When I start up the computer, there is no volume icon, no sound and device manager shows the audio device as unable to start, code 10. All the codecs etc other things under sounds are OK.If I choose to uninstall it, then run add hardware wizard, it will reinstall it no problems and the sound comes back. But next boot up it's gone again.In case of not having read previous post, I suspect some corruption occurred when I had to cold shutdown my computer.

I obviously have the correct drivers on the computer & can load them through hardware wizard - I just don't know why they don't stick on shutdown - it's as if the function which registers the entry in the register is corrupt - I know there are certain files which can be installed or uninstalled from the registry in order to start or stop a service.is it something like this I need to do?

Unknown Device: Took Long To Get Audio To Work?

Aug 23, 2009

I installed all the Windows updates and loaded the drivers off the utility disk that came with the motherboard. I also got the updates from the GIGABYTE website. The utility app shows all drivers are installed correctly. It took me a couple of days to get audio to work because the initial driver load got corrupted somehow and it wouldn't let me reinstall until I deleted the driver's entry in the registry. After that I was prompted for the driver again and it installed fine and sound finally started working. Everything appears to be working and there is only the one Unknown driver in my Device Properties and it's really irking me. All my drivers were installed correctly in my previous installation

No Audio Device Found After Clean Installation?

Dec 2, 2009

I recently found an old Gateway desktop in my basement. It is from a few years back, but I figured I'd do a clean install of Windows XP on it and run it in an extra room.I copied the drivers over using a program called DriverMax, and it seemed to work successfully. I had the internet right away and everything else I tried worked. The only problem I am having is that there is no sound. It also says there is no audio device found. Device Manager says I have the most up to date Legacy Audio Drivers, but I am still having this problem.Is there another driver that I might need in order for my computer to recognize an audio device.

Balloon.wav Audio Device Can't Playing Sound

Jan 22, 2008

My computer has recently started playing the System Notification sound that is defined as Windows XP Balloon.wav in the Sounds and Audio Device Properties at seemingly random intervels, and I cannot seem to find out what application is triggering the playing of this sound. I am sure it is this sound specifically as I changed it up and the change was reflected in the sound that was playing. I have also been checking the event viewer under Administrative tools and haven't noticed any events that correspond with the issue at hand. It's slowly driving me crazy! I have heard a ton of good stuff about your forums and thought I would give it a try.

Sudden Loss Of Sound: Audio Device Not Detected?

Dec 5, 2008

I decided to launched a game, and realised there was no audio. I tried to bring up Volume Control from the system tray, and was greeted with the error "The audio device supported by this application is not detected. The application will exit." Didn't sound good. BTW, this was while using my Creative SoundBlaster Audigy SE card.The next thing I tried to do was to connect speakers to the integrated card and see if that worked.

I then went all out and uninstalled the Creative and Soundmax drivers and utilities completely, rebooted, and installed them both again afresh between reboots. Still no luck: Same errors. I also tried switching the PCI slot for the audio card as the previous slot was directly underneath the graphics card, but this didn't do the job.

Unable To Access The Volume Tab In 'Sound And Audio Device

Sep 13, 2005

I have a volume control icon at my system tray...then, all of the sudden, the icon shows a "mute" status...i tried to unmute it by double-clicking the icon to access the volume control...nothing happened...i went to Control Panel>Sound and Audio Devices...also, nothing happened...i thought that this applet (mmsys.cpl) in C:WINDOWSSYSTEM32 was corrupted, so i tried to run it from other folder containing that file but still, nothing happened...at this point, i don't think that all 3 files were corrupted...the only way to control the volume , and to mute/unmute is by using the Creative Surround Mixer (i have an Audigy sound card),which work flawlessly...The wierd part is, even i unmute from here, the volume icon at the system tray still shown as 'mute'..but i can still hear all the sounds and songs...Then, I've discovered that in AudioHQ (also from Creative software), under the View>Multimedia Propertis, I CAN actually access the 'Sound and Audio Devices' applet...this will open the 'Audio' tab...other tabs like 'Sound', 'Voice' and 'Hardware' is also accessible from here, BUT, when opening the 'Volume' tab, it hangs...i could't access this applet any longer...the only way to close it is to end the process (rundll32.exe) in the task manager.That's why i conclude that the volume tab in the applet is problematic.
