No Sound And And Unknown Device On Audio Bus Trying To Install?
Sep 9, 2009
I don't have sound and haven't for the past few days and then this morning a Found New Hardware Wizard keeps popping up trying to install software for an Unknown Device on High Definition Audio Bus.In the Device Manager, there are yellow question marks near Other Devices and then below it, in sub categories is a list of at least 20 (!) Unknown Device on High Definition Audio Bus.In the Audio Device section, there are NO Playback Devices, NO Recording Devices, No Midi Playback and the same in the Voice section. Usually I have Realtek listed there.

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

I have a Toshiba laptop M115-S3094 Satellite with Windows Media It's less than a year old.In the beginning it ran great. Now I can't get any audio. I tried the Fan in Comcast, it plays the videos, but no sound. I tried a DVD. No sound. I ran the troubleshooter. No help. No music in Windows Media Player either.There are so many devices on this laptop. I do get the sound when windows opens and closes. I have had sound on the Fan video clips and Windows Media Center in the past. I recently completed the Window authenticity.

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.

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.

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.

I recently did a fresh install of Windows XP on on my laptop and since then I haven't been able to get sound working. Almost all drivers have been installed and Device manager tells me they are working just fine. My audio one is a Sigmatel driver, if that matters much ... but there's 5 others listed under "sound, video, and game controllers."Almost all drivers, as I said, the ones below I didn't install for various reasons:
* Sony Visual Communication Camera Driver -- It is actually installed, just disabled because it gives shutdown issues.

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.)

Last night I installed ATiTool 0.24 over my 0.25 version (stupidly). I also did a BIOS update and installed Cat6.3 and then AVIVO converter. When I rebooted, I had this new PCI device requiring a driver,but it's an unknown device and doing an auto update helped me.I can't get rid of this pesky PCI device (tried uninstalling but Windows detects it again after restart/boot-up). All my stuff is working, so I don't know where this critter came from?

I just got a new computer with an AMD Duron processor, 512 M RAM and Windows XP. Only problem is I've got no audio. I've checked BIOS and sound is enabled but Windows doesn't seem to recognize that the speakers are hooked up. When I tried to play system sounds from the Control Panel, I got an error message that said cannot play sound, your sound card may be in use. The computer was a gift that was bought used and the shop didn't have any documentation with the system. I think this might be a driver issue but I'm not sure how to find out which driver to try.

I'm using Win XP SP2 . I installed a second CD rom drive which was obviously no good because it caused the other one which is perfectly ok to show up in the bios as an unknown device. Both showed up in the bios as unknown device but the the first still showed up in system hardware the second one didn't.I removed the second one from the computer and the first one then showed up accordingly in the bios as the proper device but the bios is still saying the second one is an unknown device. Every time I start my computer I get the message secondary device missing press the F1 key to continue.

Just put together my new system and all is working well, but I am left with this unknown exclamation in the "device manager". I can't figure out what it is.
The only thing device manager says is,Location: on PCI standard ISA bridge The drivers for this device are not installed. (Code 28) and in the conflicting device list it says Memory Range FED00000 - FED00FFF not available.

i installed an usb device,and all the drivers for it,it worked for two days, it was recognized.Now it will not recognize the device.I have tried uninstalling and reinstalling the device drivers, all the software that used the device. and even tried to install the driver by locating with 'have disk' browse. i have tried all the directories that the drivers were installed to, and then some. and also the install disk. Device manager says that its an unknown device, and theres no problem with it. but will not update to the proper drivers. How can i alleviate this problem short of reformatting my computer.

I have a Gateway 710X running Windows XP Home Edition which has been patched up-to-date.Connected to this is a Western Digital 80Gb external hard drive Model Nr WD800B005-RNN) The drive had been connected to the USB port for a long time without any problems in access. Tonight, however, it seemed to have been discovered as disconnected, and we reconnected the USB cable.Upon reconnection, we get pop-up windows in the lower right corner which state: (1) Found New Hardware: USB Device then switches to (2) Found New Hardware: Unknown Device then appears (3) Found New Hardware: Your new hardware is installed and ready to use then appears (4) USB Device Not Recognized

I just installed Windows Xp on a puter. After installing all the drivers including the video card drivers from ATI's website the computer discovered an "unknown device on ATI Radeon X700"The motherboard is a gigabyte 8I865GME-775-RH and obviously a X700 Radeon Video Card. AGP drivers, chipset drivers and the like are all installed. The video card showed up as an unknown device when I first installed, I put in the catalyst drivers and it detected successfully, upon reboot this new unknown device came up and I can not seem to find any drivers for the thing. I tried reinstalling the catalyst drivers as well to no avail.

All of a sudden, the imaging devices attached to a computer with Windows XP Pro SP2 are showing up under the Unknown category in the Device Manager. The
devices are listed correctly by their names under Unknown, but the software won't communicate with them.Windows can see the devices, but it does not know what type of devices they are. It is only the imaging devices. One is a Canon 4200F Canoscan scanner, the other is a Sony Camcorder, and the third is a hardware capture device (Pinnacle Moviebox). The Canon scanner is a USB 2.0 device, while the other two are attached through firewire ports.

I installed a fresh copy of WIN2000 on my IBM Thinkpad A21m but I am having a problem setting up a device in Device Mangager. I have no idea what is going on.
When i reboot the laptop it prompts me that it has found a new piece of hardware and it wants me to install the driver for it. The problem is that I have no idea what device it is since all the devices that should be working are working - so i don't know what to do.
The clues that I have noticed that might help:
- the laptop takes a LOOOONG time to boot up (3 or 4 mins), and is sort of sluggish in operation (compared to how it ran when i bought it)
- my internet connection is super slow ( I have a DSL router that serves 3 computers incl. mine, the other two have XP and everythign runs smooth)
- the unknown device says it is located on the the "Microsoft ACPI-Compliant Embedded Controller"
Would any one know what Device this "Unknown Device" is??? I just need to know so i can install the driver so my system can run properly.

I have a bit of a problem, for some reason my system is showing "unknown" in my device manager, the only hardware that has been installed on this system is a new video card, (radeon HD5570) that seemed to go in without a hitch. Simultaneously, with this appearing I started having issues with windows media player not play .mod files, using web help it says that I need to update my audio drivers, but according to Dell they are good. Would really like some help with this.
