I had vista installed on my laptop, Acer 6920, (first OS) and it was direct from factory so everything worked fine. I then installed ubuntu and everything still worked fine. I then deinstalled both of those to put on windows 7 RC where all my hardware was working perfectly (minus the fingerprint reader but i honestly couldnt care about that thing) so my computer eventually got pretty bogged down with crap to the point where boot was about 30 minutes. during this whole time my sound seemed to work, but near the end windows stopped finding any internal sound related hardware (the speakers and the mic). For other reasons i did a clean reformat (3 times) and reinstalled 7 Professional 32 bit and when i booted i downloaded all the drivers and everything seemed to install correctly, but when i rebooted the sound still didnt work nor did the mic. the exact error message windows is giving me is "No Audio Output Device found" however when i plug in a headset or a bluetooth adapter + headphones there is audio and it works perfectly. I really need sound to work as some programs crash if they dont detect a sound output and also for monitoring audio recordings.
I have tried installing all of Realtek's drivers. Literally all of them. None of them worked what so ever despite clean installs and deinstalls.
I now am running 64bit and ive almost given up on this problem. I bearly saved this computer and i dont wanna have to buy a new because of sucha stupid issue like this.
More info:
Under the hardware manager in windows there is no tree for sound devices. there was an unknown component which i put forceware on as i thought it was the sound device but no go.

PROBLEM: Six Months Ago, the Sound Device Stopped Working, I get the following message (No Audio Output Device is installed): It is as if NO audio device is installed on the motherboard.
Here's the catch: Sometimes when I START my computer the Device Works, and Sometimes It doesn't. If I restart the computer like 20-30 consecutive times (IF I'M LUCKY) chances that in one of these restarts the device MAY Work. Sometimes i go weeks without Audio.
Here are *some* things I've Tried: 1) Format the System:
Different OSs I've tried: Windows XP Home/Pro, Vista, 7 and Linux.
The expirience the same problem with all these OSs. So It's not an OS thing............
I recently received this acer laptop as a gift. Right from the first time I started it I noticed issues with the sound. With any audio that played there were crackling noises.The crackling got worse and worse so I Decided to restart the laptop and then the sound stopped working altogether.I tried reinstalling the Realtek HD audio drivers that came with the laptop but that didn't work and I still got a "No Audio Output Device is Installed" message in the bottom corner.
I tried reinstalling the drivers AGAIN, and the sound worked. All seemed well until I woke up the next day with no sound yet again.I then tried downloading new drivers from the realtek website, even these drivers didn't work. The only solution to the problem seemed to be basically uninstalling and reinstalling the realtek drivers until they worked, and even then, the sound would still crackle horrendously.After getting fed up with this issue I tried to refresh windows, and even this didn't work.I have tried everything I can think of .....
HP Pavilion dv6-7030tx Entertainment Notebook PC Windows 7 Intel i7-3610QM CPU @2.3GHz 8Gb Ram  I have no audio. It has been previously working, but suddenly stopped. On the small speaker icon there is a red cross indicating "No Audio Output Device is enabled" When I log on to the computer i get a window that says "CWindowsSystem32AUDIOSES.DLL is not designed to run on Windows or it contains an error."  I have attempted to Troubleshoot but unable to get any sound. I have updated the Audio driver, but it is the up to date driver.

HP G60 Notebook PC, Device:My conexant high definition smartaudio 221 Status:error(18) Driver:CHDRT32.sys Version:4.58.1.0. How can I installed back into my laptop.
Audio issues, "while playing world of warcraft. most attempts at running background audio like music or team speak results in under water gargle sounds as if the sound card cant run two programs with audio at the same time"
I've reinstalled the drivers, and tweaked with the sound settings and more without any positive solutions.
Video card issues, "video card is a 9500m GS however has been having frame rate issues with world of warcraft and other basic games. I've tried to find updated drivers of the video card online with sad results from acer's side with their lack of work on updates."
My volume icon in the system try reads "No audio output device is installed." The audio device is not even recognized in the device manager (i.e. there is no yellow exclamation point or conflicted device to update a driver to). The system simply does not recognize the fact that a sound device exists.
I have tried many, many things: Fresh install (as per the sticky-guide) of Windows Vista x64 Home PremiumFresh recovery from system recovery partitionTried all versions of the drivers from the HP support page (Realtek and Conexant) --- I believe I have conexant, though.Safe mode driver installsDriver installs on a driver signing rebootPutting the computer into hibernate, then resuming (odd, I know.. I heard it worked sometiems).Made sure "Windows Audio" service is enabled in Administrative ToolsServicesInstalled Windows XP drivers for "Microsoft High Definition Audio controller"Flashed BIOS to most recent version F.32Updated chispet drivers to most recent nForce availableeInstalled Vista SP2 I'm sure there must be one or two more things that I've tried and just can't remember. I am running Windows Vista x64 Home Premium with SP1.
I have an HP DV6700 Laptop, and I recently installed Windows 7 Professional (64 bit) (The full version from MSDN academic alliance, not the release candidate). A few days afterward, I had an issue where my speaker icon has a red "x" over it, and when I hover over it it says "no audio output device is installed". The funny thing is that the speakers worked after windows update installed an update, then they stopped a few days later, and I cannot for the life of me get the speakers to work again!
Suddenly my computer has no sound what so ever. It doesnt work when I plug in headphones, either. When I hold the mouse over the sound icon in the bottom right corner of the screen it says, "No Audio Output Device is Enabled."  I have Windows 7 Home Premium 64-bit Service Pack 1. My computer's product number is XZ046UA#ABA.  Do I need to install a new driver, or something else?
I have a dv7-7270ca notebook and since a restart due to windows 8 updates I now have a red x on the speaker icon. Â I installed the HP driver for this model but it has an error in device manager that says:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
I did run an audio test using the shut down-F2 and passed and could hear the sounds in the test.
i bought a acer laptop @ bestbuy and it came with preinstall vista home. i used the computer fine and all and the internet connects to my router find and was surfing the internet. i then decided to install a fresh copy of my own vista ultimate because i dont like the preinstall stuff that they did because it just clutters up space. after i finish my install of vista ultimate, my laptop doesn't connect to the internet. i know this is simply but i dont see network adapters under the device manager in the computer management screen. i am worried because if i have to install the driver, then i would see some icons with a yellow exclamation mark, but i dont see NETWORK ADAPTERS AT ALL. i dont know how to solve this? any help would be greatly appreciated. thanks all. i've tried to press scan for new hardware changes but still i dont see the network adpaters. i thought if you install vista ultimate, then it will install the wireless drivers for you too.
I have a Probook 4720s with Windows 7 Pro. Connecting my laptop to the TV with a HDMI cable worked fine then suddenly the next time I did this I had no sound and when I right click the sound Icon I noticed it read ATI High Definition Audio device not plugged in. It worked once and now it won't, I miss it. The driver is up to date.
type of connector needed for digital audio? I have not been able to confirm that my Acer 7720-6395 NB has a dual digital connection. The manual calls the jack a S/PDIF but looks like and allows a stereo plug to work. Talking to the folks at the Sony store claims that the jack could be a dual connector and would work with a headphone or a optical connection. Would love to watch a blue ray movie with 5.1 sound......
I need to record audio output, but there is no "Stereo Mix" in Sound>Recording. I understand that this is a common issue with some laptops. Aspire 4830T?
i've recently installed windows xp (dual boot with vista), then decided to remove it and do a fresh install. however when i held ALT and kept pressing F4, but nothing happened.
i've searched this forum, and understood that the problem is that xp reset the mbr with its default file. so how can i fix the mbr?
i tried downloading the mbrfix[url]but i didn't work (maybe bcs it's for 5610).
I was under Windows Seven when i got some virus problems. i format my whole HDD and start to have some problems. sometimes the computer randomly stops. Often when i'm copying files or defrag the disk. there, my laptop seems very hot. it shutdown when I play (whatever the game played the temperature are (according to SpeedFan) about 100°C))
I firstly think about dust. so i have clean by removing the trap at the bottom and cleaning the ventilation holes.
That change nothing. my computers stops 10 minutes after the game's started. but it boot right now after it stops, (i've head that in case of a too ward hardware the computer will not boot right now after it stops) metimes after a program ask a reboot and i say yes , the fan don't work at all after the reboot.
I am in the process of doing some minor upgrades to my 6920g, gonna be adding a T9500 and 500gb drive in about a week, and was curious if it is at all possible to add a blu-ray drive to my model. Now I know several models had the option to come shipped with the drive and a quick search on google came up with replacement drives for those models, so mainly I want to know if any of them will work in my 6920-6864.
Also on a semi unrelated note I am trying to find the 6920g service guide to help me with the processor upgrade, but all I can find online are places selling it. I know the link to it can't be posted here but if someone has it let me know and we can get in touch elsewhere.
when i insert a dvd into the drive, the drive tries to read the disc and the yellow led turns on, after a few seconds it finishes reading and when i go to open it in computer, double click on dvd drive, there is nothing on the dvd. i tried a couple of different dvd's, but the same thing happens.
One thing that makes me think that the problem is software, is my ability to boot from disc. i can boot the recovery disks, windows xp, linux... whatever.
i've updated to bios v1.14 from 1.10, but the problem persisted. i always tried removing upperfilters & lowerfilters and even restoring to factory default settings. nothing worked. i remeber that this happened to me about 5 months ago, and that suddenly it was fixed, but two weeks ago it returned.

Well I just Bought the last saturday an acer gemstone blue 6920. The model with the intel gma x3100 and it came with Windows Vista Premium. The first thing that i did was to install the newest drivers of vga..i downloaded them from the intel website but the results were ugly..
I decided to downgrade the OS to Windows XP Pro...And I did it i have to put my HD on IDE MODE from the bios and install without a problem..
I downloaed the xp drivers...
After this i played fifa 09 but in two time the game crashes and when i closed the game with ALT+F4 i saw the next message:
THE SCREEN DRIVER IGXPRD2 STOP WORKING etc etc and the screen went like if I doesnt have any driver so i have to restart
Searching via google I found that there is an old driver(6.14.10.4859) that makes the performance on gaming a little better...well i found the driver and installed.
The results? Yeah it was true the fps in games were a little better but when it seems to be all normal THEN THE GAME CRASHES AND BSOD!
Yeah Blue screen of death so i have to restart...only have been happenned two times and the gameplay is much better than with the latest drivers but i need to do something with that BSOD...It doesn't appear much but its a problem.....
i got a problem with my dvd burner ( Slimtype DVD A DS8A1P ATA Device ). I tried to burn a DVD-RW. But it just wont burn, although it does reconnizes the DVD.
I already came to some threads here, which said this particular drive has problems with DVD burning. But why do they place it in my laptop?
I got some great information from the people on here previously and I'm back for more advice.
I have the ACER 6920 Gemstone Blue, it has a built in webcam called Acer Crystal Eye.
As I get older the paranoia gets worse, and lately I've been wondering who is watching me! I have been using Skype, Msn, Yahoo messenger and Facebook to stay in contact with family back home. I am not at all convinced about the secuity of these programs and wonder if I have been hijacked.
How can I check to see if my webcam has been hijacked?
Is there some where that I can look to see if it is in use?
I have the above model and it seems to be performing quite nicely. However, what I've noticed on all Valve games is that after a few minutes, the frame rates drop from mid 70s-80s (low) to 10-15 regardless of whatever resolution, texture or ingame setting I change post this sudden drop. restarting the game makes the problem temporarily dissapear but is back within a few minutes. The effect is especially noticeable when there are about 30 zombies on top of you
I've tried disabling one core, reducing sound to low and have even monitored temperatures via nvidias system checker as well as speed fan. At no point does GPU/ CPU temperature exceed 60 degree celcius. Have also tried several drivers all the way from 178.x to 182.x (using modified infs) to no avail. Please share your input regarding this problem.
I also accidentally uninstalled acer bioware protection and upon reinstalling cannot set it up since clicking a blinking finger on the setup menu states "Unable to select fingerprint device!"
Music sounds rather "tinny" and baseless using these inbuilt speakers. I assumed with all this dolby gee whizz, id get a sublime experience
My Acer Aspire 6920 Laptop freezes occasionally, and nothing but a cold shutdown fixes it. Sometimes after I turn it back on again, the keyboard is unresponsive until after I've logged into my Windows 7. If I was playing music at the time of the freeze, it plays the last few seconds of music in slow motion over and over again.
There does't seem to be anything in particular that causes the crashes (sometimes I'm running games, other times it was idling).
How can I stop it freezing?
What I've tried: Reinstalling my Windows 7 64bit, Installing the latest drivers (from various sources)
I took a video of the laptop in it's frozen state, if this would help anyone? If it would, I can upload it to youtube... Basically nothing but a cold shutdown (holding in the power button) does anything.
