Fluorescent Light Makes Device Disconnect Sound?
Dec 27, 2010
With my recent purchase of my new Windows 7 computer I added a fluorescent light above my workstation. Its around 21" long and mounted about 3 feet above my monitor and PC. Sometimes when I first turn on the light I hear the "bong-bong" sound of the device disconnect sound from the PC. This does not happen every time but I would say about 60% of the time it happens. I do not see any indication than something actually "unmounted" but this does have me stumped. I know a fluorescent light does put out a frequency but I have not heard of anything like this. I have stopped using the light for not until I can figure out if it is actually interfering with anything.

After opening the Sound pane (from right click on the tool bar speaker icon) I clicked on the Set Default button near the bottom. There I clicked Disable (I think that was the term) for the onboard sound card (Conexant). Now the sound card is gone and I can't find how to turn it back on. I'm not very sophisticated but I have checked the usual suspects even downloaded the driver etc.

I always used "switch to other user" when I left my laptop behind for a while (i.e. when I was going to sleep or leaving the house). As I never turn off my laptop (barely never), the point is that I don't want to get people to use my laptop without my permission browsing through my files etc. It's not like I've got something to hide, I just don't want it.
It used to work before, without making the internet disconnect. I made sure that Windows is not configured to turn off the network card when idle for some time.

I have a PC I assembled last June. After I loaded it up with my applications and connected my devices I began getting device disconnect sounds as well as a few device connect sounds. I've been troubleshooting by disconnecting all devices then adding devices back one at a time to try to find the culprit. I'm not getting consistent or convincing results so far, but will keep working on that approach.
A Web search on the subject returns lots of results where users are experiencing these sounds. Answers are sparse. And antagonizing! I have not found any hints as to how to extract from the system what is actually happening. What I am looking for is if anybody knows where in the system I can find a log that records device connect/disconnect events associated with these sounds.

I know this doesn't really give much away to my problem but i'm just as confused.
My laptop has recently started making the little beep noise that would occur when inserting a usb device etc. but i haven't inserted anything into the laptop at all?
I have checked various windows device programs but to no avail, there are no yellow triangles in the device manager, so i'm unsure as to what has caused this?
I have also system restored but it still proceeds to make the noise.

The title explains the problem. I can't find anything that would set this off. Everything else seems normal. It's been doing this all morning. Probably, if I reboot, it'll stop - but I want to find the source of the 'bing.' How can I trace it down?

About half hour/hour into my online game of L4D on VS mode my game freezes up and makes a constant buzzing sound? And I have to manually hold the power button on the comp to reboot and during boot it asks to start windows normally or last known good config.
Anyone have any trouble like this? running 64bit Windows 7 build 7600 with 8800GT 512. I'm thinking its a driver issue? I forgot how to check which Nvidia driver I have..

I've had the freezing problem for months and so far no solution. My laptop runs fine when I play games, or browse, as long as i don't watch videos or listen to music, it doesn't mind if online or from my drive. Tried different software but no luck. I would think it's hardware, but i don't have this problem on linux.I ran windows 8 for a few days, didn't see the freezing there, but I don't like the OS.I think the problem is with the audio drivers or something, I tried old and new ones, but no result.I am running Windows 7 ultimate 32bit (64 doesn't help either). My laptop is Acer Extensa 5635zg. I attach the Windows_NT6_BSOD_jcgriff2 report+ the everest report inside the zip, where you can find the hardware information about my laptop.

I have an emu 1820m soundcard installed in my computer. It seems to be functioning perfectly. I can play dvd'd, cd's, iTunes, etc and the sound plays through my speakers without a problem. I want to record some sounds from a dvd but i cant get anything to record. Recording device is set to Wave EMU DSP as the default device. Im using Audacity to record and have set the recording preference device to be Wave (E-MU _-DSP). When I hit record I get an error 'Error while opening sound device. Please check the input device settings and the project template'And I cant record anything.In the built in Windows sound recorder, when I hit record, I get this error 'An audio recording device cannot be found' Everything seems to be functioning perfectly, yet i just cant record anything.

I'm in a pickle with my machine and Windows 7 after this latest update. On startup I get an error from MMDevApi.dll saying that it might not run on Windows or... something else. This also occurs anytime a program tries to use the sound card ie. WoW, Yahoo IM, Live IM, SL, etc. I've updated my sound card drivers to the newest ones. I still get an error that says the device is detected when going to "Sound Devices" in the control panel.
Trying to adjust the sounds themselves leads me to the Windows Audio thing... which won't start even from the component list.

[window 7 ultimate]
normally i only have 1 sound card/sound device in sound settings when i use hdmi with my tv, i have 2 sound devices in there, and i can choose 1 one of them as default, and all applications i run will play sound on that default device, so i choose hdmi (my tv) as default, open chrome for my mom watch movies, sound play on my tv (hdmi), that's what i want and i open firefox, go to Internet, sound also play on my tv (hdmi), that's not what i want, i want it (firefox) to play sound on my pc, so my mom can watch movies on tv, and i can watch Internet on pc
is there a way to do this? a way to set per-application sound card/sound device setting? i know some programs like windows media player or vlc can let you choose sound card, but firefox, chrome do not. i tried indievolume and it did not work, even uninstalled, reinstalled but did not work, or is there any browser that let me choose sound card setting (like wmp and vlc, but these 2 are not browser)
and does anyone know if mac or windows 8 has this feature as built-in? if windows 8 does then i might upgrade

I have recently installed Win7 Ultimate on my PC - was running Vista Home Premium.Had no problems until last week. I had a BSOD, which surprised me, haven't seen one of those in a while. Major error on my part to not write down all that sais, but there it is.Now I have NO sound at all. Actually, my computer does not recognize the monitor speakers, nor does it recognize external speakers, when I tried using a pair of them instead, nor does it recognize headphones when plugged in to the jack. The computer informs me that the device is simply not plugged in - even though it IS.I have downloaded and updated every driver I can think of to no avail. So I am now at a standstill as to what to do.

For my radio project and podcasts I've invested in a digital microphone. I also got a wireless keyboard and mouse with volume control, not very important but it factors in.
When I start Windows I have two sound devices: The actual speakers and this ProSound mic. Under the actual speakers would be things like VLC and under the mic would be other vital things like Iron (Chrome). If I want to watch/listen to something online I have to plug out the mic. This puts all the programs under the Speakers device. If I plug it back in these programs RETURN to the ProSound mic.
So first of all I need to know why my programs made this choice and how do I put a stop to it? Secondly how do I make my speakers my primary device so I can use these awesome volume controls I paid out the *** to use.

I could really do with some help. Just installed W7 64 but when I come to install drivers it cannot even detect my x-fi SB at all. Thus I cannot install the driver. No sound at all - I am at a loss. Does anyone have a solution? ps I have a ASUS ABN-SLI Nvidia chipset.

I have system with multiple Sound playback devices. Most of the time it needs to be on the first entry in the list of devices (HDMI output with me).I'm looking for a way that when I have manually set it to another device in the list, and then shut down the pc that at the next boot it automatically reverts back to the first in the list without manual intervention.

i am in the process of setting up my audio preferences but i'm confused about various aspects of windows 7 audio settings in the device/sound manager. my computers are part of a recording studio setup, and as such, one of my computers has an maudio 1010lt audio interface card. as my studio is also an entertainment setup, i began to investigate if win 7 has some kind of audio "profile" manager, whereby i might be able to select various "devices" or outputs that would automatically be selected when various applications are started. for instance, when i use my daw(reaper), i would like win 7 to automatically select the maudio card as the in/out as the maudio outputs(8) are connected to a patchbay, and are normalled to be connected to an analog mixer. however, if i am listening to audio on the net, like Internet etc, i would like the mobo onboard stereo(front) outputs to be selected by the os, as they are connected to a pair of standard computer powered speakers, as i do not want the mixer powered on during regular listening. and then there is the movie thing. since my mobo has stereo, 5.1, and 7.1 as well as s/pdif output jacks,(and input), from what i understand, the s/pdif output must be used for sound surround as the onboard realtec chips decode dvd etc to the s/pdif outputs, which i would like to connect to a soundsurround reciever, with 5.1 speaker setup, of which the front speakers are used for standard stereo listening..anyway, as i looked at the device/sound manager screen, i saw an "hdmi" device in the list.(see screenshot). well, i don't have anything in the computer that has an hdmi output. so, i am curious. can anyone tell me what this "hdmi" device is or what it is referring to?

I'm on the verge of re-installing Windows. It started earlier today, I'd just installed Call of Duty: World at War off Steam, tried to launch it and it kept crashing. Tried a few things, but nothing worked and read it might be a sound driver issue. Tried updating my ASUS Xonar DX drivers to the latest version, but once the PC had restarted I had no sound and a the speaker on the taskbar said there's no output device installed.
Uninstalled these drivers and tried installing the ones I was using and same problem. I opened up playback devices and the default speakers were my monitor as I connect via HDMI from my graphic card to my main monitor. The "set default" option was greyed out and I couldn't change the default speakers unless I disabled the HDMI audio, but still I had no sound. Tried uninstalling the graphic drivers and re-installing the drivers first, but still nothing. Even when the only audio device was the sound card, there was no sound.
If I troubleshoot, it says the audio device is disabled, even though it isn't. I've checked all the audio services and they're all running. I even tried enabling my onboard audio again, but I still get the same problem of the audio device apparently being disabled. I ran an sfc /scannow, and that fixed a few things, but still no audio. Only thing I can think of doing now is just re-installing Windows.

For about 2 weeks ago my battery on my laptop (ASUS Eee PC - Windows 7) got low and the computer turned off. When I turned it on again the sound on the computer didn't work, the sound symbole on the right corner on the bottom has a red X sign. I've just recovered my computer to fabric-new and the sound still doesn't work and the red X symbole is still there.When clicking on the sound symbole with the red X on the right corner in the bottom it says "identifying problem..." and then it says that it couldn't identify the problem... My webcam on the computer doesn't work either after that.On control panel it says "no audio device installed" and when I deleted RealTek and downloaded it again it still doesn't work.
