Acer :: Aspire 5520 No Sound Device Installed
Apr 26, 2010
I have upgraded to Windows 7 x64 (a fair while ago) and rencently it has started to come up with "No sound device installed" over the speaker icon in the sys tray.
This happens about 50% of the time when the computer has started up.
It never has any issues once the sound is working.
When the sound is not working "Sound, Video and Game Controllers" in Device manager is missing and i cant find the "Reltek HD Audio" device any where else in device manager.
It's just had a freash install of the OS and is still not working reliably.
It's got the latest Win 7 x64 drivers from RelTek

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 .....

 Acer travel mate 4060 * upgraded to 2 GB ram and windows 7 Home premiun 32 bit has just been recovered from a crash.
I am sending this message from the same computer. My built in speakers are not functioning . However when I connect an external speaker with a USB connection, its working perfectly well. I can watch videos and play music. I checked and it appears that there is no sound device installed.

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 laptop of type:
ACER ASPIRE 7520-5971
Systems Specs:
AMD Athlon 64 X2
384MB Nvidia Geforce 7000M
4GB DDR2
MOTHERBOARD:
MANUFACTURER: Acer
MODEL: Fuquene
CHIPSET: NVIDIA nFORCE 560
BIOS: Brand: Acer, V1.33
SOUND DEVICE: Realtek High Definition Audio.
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............

Faced with the problem. No sound after the laptop. When you try to check the sound device, a window pops up "the device is already in use by another application." But no program is not running. After rebooting the laptop sound occurs. Drivers are all set.
Audio device Realtek ALC269
Win 7 Pro SP1 (x64)Â with all updates
Motherboard 20208
Chipset Intel Panther Point HM77
BIOS Version H5ET84WW(1.22)Â (11/26/2013)
UEFI boot mode, not Legacy.Drivers for sound downloaded from realtek.com.tw. With standard windows drivers sound is always there. Tried the previous version of the drivers - ineffectually. Could it be that the problem is due to the UEFI boot mode? I do not want to reinstall the OS mode Legacy just to check it out.

I have a Aspire 5520-5912 laptop I am trouble shooting for a relative that randomly shuts down just before, or shortly after it boots to windows.
I have tested the hard drive in my Desktop and scanned it for viruses, swapped out the memory, re applied thermal paste on the cpu heat sink and made sure it was not clogged with dust.
I think I have it narrowed down to a bad MB or CPU but was wandering if anyone else has had any issues like this and what the problem was.

I think my cpu and gpu temps are too high. The idle temps are: cpu: 40-50°C, gpu: 60-70°C. I'm installing WoW now, and the cpu is 74°C, the gpu 75°C. My CPU is: AMD Turion 64 x2 TL-60 (2.0 GHz), graphic card: NVIDIA GeForce 8400M G. I'm using SpeedFan to watch the temps.

I have a new OTB acer aspire 5520, and on initial booting everything worked sweetly but when i am trying to access my crystal eye cam on YM or any IM programs it says the webcam is not connected, Now I checked device manager and there is no webcam, so i installed the driver from the erecovery management tool I tried first the BISON driver and utility without success upon installation the program says the computer should display a "found new hardware" message, but nothing showed up. then when it restarted my machine and when i checked on device manager still no cam... next i uninstalled the BISON driver and installed the 2nd one (SUYIN) with the same results. I searched the support and download section of ACER online and tried a third driver the CHICONY and still the same results.. Finally i re installed my system to full factory default and re tried everything still the same problems...

I got a new Inspiron 15R 5520. The problem is I can't boot the laptop from a USB stick like I did on N5040(My 2 years old laptop), and there is no option to do this. First, I hit 'F2' to enter the BIOS setup page, there are only 3 options under the boot device: Hard Drive, CD/DVD, Network. I restart the computer and hit 'F12' to select boot device, still no USB.
Does Dell freeze the function to boot from USB device?

I'm in the repair field and I've got a customer's Aspire 5520 that was brought in for overheating. The machine had gone to Iraq, and the customer has indoor dogs..so yes, the fins on the heat pipe were very clogged. Got it all cleaned out, and the machine is still shutting itself off after between 10 minutes and 30 seconds of use.
Now, the machine isn't overheating. SpeedFan and a few other CPU temp utilities are showing the CPU to be around 45*c when the machine is randomly shutting down. 45c is not what I'd consider hot for a Turion x2.
It's not a RAM issue, I've replaced the CPU and am getting the same symptoms.

I have an Acer Aspire 5520 laptop with 320gb hd space .. 8600m gs video card ... 4gb ram... Vista 32-bit oem.. etc.
The problem is that I've just accidentaly deleted my whole OS.
I booted with my Vista 64-bit disc so I could format one of my drives, but I stupidly formatted the wrong one. (the one with my OS)
So now I just installed Vista 64-bit on it, so I could at least do something with my laptop (watch dvds etc.), but I can't get the internet to work anymore because of all the important stuff that got deleted.
What I was using was some public WLAN.
Now it complains that a network adapter doesn't exist.. or something like that. I don't even know what that is.
Is there any way I can fix this myself? I just need to get my internet to work again.

Bougth a Acer Aspire 5520 couple of weeks ago, tried to install XP on it, thing crashed. Back on normal Vista (not from recovery) and installed the Nvidia driver(101.54 / 32 bit) which comes wit the acer website and the Nforce driver for network connction etc. Got a Gforce 8400M G with a AMD Turion64 X2(1.8 Ghz)
Now when i try gaming on this thing it's totally wack. Installed Counter-strike and World of warcraft, and both run not good... It's just lagging a lot, not internet lag, graphics lag. I tried downloading some other drivers, but no one seems to be working, mostly getting the message: 'u need a Vista 64 bit for this driver, and u have a Vista 64bit' or 'the hardware for this driver cannot be found'. No idea what to do to fix this problem according to drivers... could be really simple.

I've had my Acer Aspire 5520 for about 6 months now, and I did not get a warranty with it. Within the last month or so the fan has begun to get really loud. I have ways of quieting it down temporarily, hanging it off the table or propping it up, but even then the fan will burst into loud, annoying noises suddenly and for no apparent reason. It's kinda like a click-click-click noise, like when you put a strip of paper into a house fan (I know we all did this as a kid...) and the blades hit the paper as they go by, making really obnoxious noises...
So anyway, I'm just wondering if this is fixable, or if it isn't where I can find a replacement fan that works for my computer. I'm a software junky, and I don't really know enough about hardware, so when I went on Newegg and Frys websites I was unable to figure out what kind of fans would work for my laptop. If anyone has any ideas I would really appreciate it, as I spend a lot of time in the library at my school and I don't want to disturb everyone else in the whole building. In fact, when ever I shop for laptops, keyboards are one of the first things I look at- if the keyboard is too loud or awkward I will NOT buy that laptop.

I have an Acer Aspire 5520, and require the original CD/CD's supplied with the machine.
I do not believe requesting copies is illegal, seeing as I own the machine, its out of warranty now, and Acer UK can't help

I just started my Aspire 5520 laptop, and when I get to the desktop an error pops up saying that I can't access the location of my desktop (C:Windowssystem32configsystemprofileDesktop)
Only thing which shows up on the desktop is the recycle bin.
The Vista theme is changed to classic and I can't get it back.
Internet doesn't work
Sound doesn't work
I can't open the control panel (in safe mode I can, but not all of the icons are there that should be there)
In the task manager there's only 4 processes running:
eplorer.exe csrss.exe taskmgr.exe (of course) and winlogo.exe
I think I can open all of my programs that I got installed, but basically I almost can't do anything else.
I've been trying to use system restore, but even in safe mode it won't open.

I bought an Acer Aspire 5520 few years ago. It has a partition with Windows Vista installed on that. Unfortunately that partition is deleted completely so I can not recover my laptop to its factory setting.
Â
Is there anyway that I can install that original windows Vista again? I looked behind my laptop and there is a label with a product key. Is that useful?
