Check the device manager
and see if there is a yellow mark next to your sound device. Since it's new, call Dell.
where is the device manager located??
It's your drivers
You need to update the mots likely Sigma Tel if it is a dell Audio Drivers to Vista I think there at www.id.com
Hey I'm having the exact same problem, the audio icon has a red circle with a white x in it and says "no audio input device is installed" i have a dell laptop and i had no problems with the aduio till a few days ago when my compter had some problems and i reloaded windows (vista home premium 32bit)and ever since the aduio hasn't worked. i tried that link and installed the sigmatel driver and it didn't help? when i go to the device mananger it says that everything is functioning properly.... what should i do??
Sigmatel driver from Dell didn't help.
I have a new Inspiron 9400 and am still having this same issue. The laptop shipped with Vista Home Premium and I just installed Vista Ultimate. Everything else is working fine except for the audio. I used the same driver as the links on this forum for the Sigmatel driver and no luck. Yes, I rebooted after install.
Beyond installing the driver on the Dell site (I went thru the process 2 times just to make sure), what next can we try to help resolve this?
Contacted Dell Yet?
Resolution to Issue
When I went to Device Manager, it showed that the latest drivers had been installed and that the audio was working fine. However, if I went to the speaker icon on the bottom right there was a x on the speaker indicating it was not working. By right-clicking and choosing playback devices (same as going to Control Panel - Sounds), it said that no audio devices were installed. So Device Manager says all is well and the rest of Windows says no audio device is installed.
First attempts at fixing were the basic uninstall of the driver to have Windows reinstall. I did this and rebooted and no fix.
Next attempt was to uninstall and delete the driver completely from my computer and then download the latest driver from Dell. I did this and rebooted and no fix.
Next attempt was running the Dell diagnostics CD. I booted from the CD and audio tested perfectly fine in the diagnostics environment. But when I loaded up Windows again, nothing.
After much searching online, I found an article about Windows XP stating that the biggest conflict with the audio drivers is often the Modem drivers.
I then uninstalled the Modem driver in Device Manager and deleted it from the system so Windows wouldn't reinstall it. I then uninstalled and deleted the 'SigmaTel HD Audio' drivers and then downloaded the latest drivers again from Dell. This time it worked! Even before the recommended reboot the audio started working again. I no longer have the ability to use the modem (or maybe it would work if I troubleshot a little further but since it has been years since I used a modem I didn't bother trying).
So essentially, if you are troubleshooting Audio issues and all basic troubleshooting fails, try removing the Modem drivers and see if that helps! Of course, make sure you don't need the modem or if you do, troubleshoot reinstalling that while not affecting the audio.
Great find - this worked for my Dell Dimension E1505
I just upgraded from Vista Home Basic to Home Premium...
I followed your path by uninstalling the drivers. I now recall that after I finished the Vista "Upgrade Anytime" that it automatically re-installed the modem driver and this is when my audio stopped working. After taking your advice, what was different for me was that even though I selected the "remove files" when uninstalling the drivers for my modem and audio, it re-installed them anyway after I rebooted. In any case, things appear back to normal now. Thanks again for doing the leg-work on this fix!
Great fix - worked with Dell XPS 410 Vista Premium
You two,tbarron7 and Jflynn33, are lifesavers. I too lost audio when I reinstalled Vista Premium. Your fix worked great. As you suggested I uninstalled both the sound and modem drivers. Then rebooted and, as you reported jflynn33,Vista reinstalled both drivers and the sound and modem work.
Thank you so much for this advise as it fixed the problem I had. The only change with my problem is that it wasn't the modem that I had to uninstall. Thanks again ThatGG
hello thatgg if u could tell me what u had 2 uninstall, 2 fix audio problem.
didn't work -_-
i did everything you said, tbarron. not a damned thing worked. -_- i tried uninstalling the drivers for my modem and my audio system and i deleted the drivers. still, the system kept reinstalling them upon restart. i tried d/l the dell drivers and i could not even install them. i kept getting an error that said something was missing and i had to restart. i've had my dell for about a year now, and it's an inspiron 6400. i've searched online, downloaded all kinds of audio drivers that were vista compatible, and still nothing. plleeeasseee help!!
modem driver delete
im trying to put this resolution into effect but for the life of me, i cant stop this stupid vista to keep from installing the model driver back. when i try to delete files inside system32 drivers folder, it says i do not have priveledges when im the admin. this vista is so full proof that if someone knows how to work in sysem32, even they are having difficulty doing it.
any help would be appreciated.
It was told above ...
to delete the modem from device manager. But it could well be that it's automatically redetected. Then try to disable it. Up to Windows XP this was called "disable in current hardware profile". In Device manager it was shown with a red X and that told Windows not to use it and not care about the drivers.
Hope this helps.
Thank you very much for your helpful advice. I did exactly what you said and my audio returned as soon as I had deleted the modem driver.
remove modem from device manager
Wow! That really worked for me. I downloaded some stupid audio update for vista. I have a dell inspiron 6400 with sigmatel audio. I tried everything such as reinstalling drivers etc but when I removed the modem my audio worked perfectly with the driver. Thanks a lot.
I have a Dell Inspiron 1501 and I had to reinstall vista in order to fix an issue with windows media player ....WHY????
Anyway, when I got everything back up almost nothing worked... till I downloaded the 50 updates off the internet. Even after that the sound wouldn't work. So, I skipped straight to the last step of getting rid of both the sigma driver and the modem driver, and when I rebooted, the computer installed BOTH automatically... but it still fixed it. Thanks a bunch. And Vista people, if you read this, we're not morons! Let us mess with our computers a little! Your "safeguards" simply keep the computer from working!
best of the best
I was haveing issues with my sound "no audio output device is installed" so after reading a lot of solutions to the issue i tried the one you suggested and bammm it worked this is how I did it step by step:first go to start then ctrl panel then click uninstall a program then look for the sound device and uninstall it then exit any application and then 1. Start menu, then click: Control Panel, then click: System and Maintenance,then click: System then on the left side click Device Manager then click Action and choose from the list Scan for hardware changes click on it and then the system it's going to install the drivers automatically and you're done .That's exactly how I did it and worked for me I restarted the computer and everything was back to normal .
no audio output installed on vista windows
thank you for Grif link and His solution. I download Sigma Tel audio driver and got back with sound. May I buy you a drink MR Grif.
Didn't Dell supply ...
a full recovery CD/DVD (with instructions, hopefully)? Just reloading Windows isn't enough.
No sound or audio in Inspiron 700 Windows XP
Hey out there, can you please help a techno-phobe? My kid is home from LSU with a laptop with no sound. She can't hear her music or UTube, but video works great. I know it's a crummy laptop, but we're trying to band aid it until she graduates and buys herself a better one.
Dell Inspiron 700 Windows XP--there is no sound and no error messages. Of course the mute button is off. We went to the Dell website and downloaded the audio driver, but still nothing.
We'll try anything short of buying a new laptop or motherboard.
You'll want to repost in the Windows XP forum.
You've Posted In The Vista Forum...?
The computer you're having issues with is running XP.. I suggest posting your question in the correct forum at the link below:
Before doing so, open the Control Panel, double click on the "Sound & Audio Devices" icon, then in the "Volume" tab, in the "Speaker Settings" section, click on the "Advanced" button.. Make sure that "Laptop Stereo Speakers" is selected.) I know you mentioned this, but try visiting the Dell site and installing the updated audio driver for your particular model. See the link below and make sure the model number is correct:
Dell Inspiron 700m Driver Downloads
(If that doesn't get it done, then the sound card may be toast.)
Hope this helps.
No sound, sound device, or controls
Solution: For Windows XP, open the Control Panel > Sounds and Audio Devices properties sheet. On the "Audio" tab, for Sound Playback > Default Device click on the 'down arrow' and check to be sure the proper audio device is selected. Typically, in the case of this problem, something like "modem line 0 playback" has replaced the proper audio device as the default.
Changing the selection back to the correct device will fix the problem with no reboot necessary in Windows XP. In other Win OS setups reboot may be required. You can use AIDA32.exe, or Everest, downloadable from MajorGeeks and other sites, to identify the sound device(s) on your machine.
This problem occurs frequently enough (often after reinstallation of or changes/updates to Windows) to be described frequently in help forums. The issue and most likely solution has not changed much since 1996 or earlier, when I first encountered it as a novice. The most common cause is the selection of the wrong - typically the modem - device as the default instead of the sound card. The modem cannot play many of the files used for system sounds! Or respond to Media Player sound features. The first step, ALWAYS, is to check and make sure that the right sound device is selected as default in audio device setup.
Unfortunately advice given for this situation is often misdirected. Typically, advice is given to uninstall and reinstall the audio card - sometimes recommending physical removal and reinsertion of the card or even its replacement - or reinstallation of the sound card drivers or installation of entirely new drivers for the card. Sometimes users are told they will have to reinstall Windows. (Of course new drivers will be needed when the OS has been upgraded, as from Win 98 or ME to Win XP.)
All of these things may - in some cases they apparently do not - result in correction of the basic problem by forcing the correct selection of the default device. But that seems a lot of trouble to go through, just to change the default device from the modem - or some other obsoleted and redundant device - back to the device which should be handling sound on the machine.
Here is what I do by following the second step like you said:
Oh, I use windows vista x86 after I upgraded to ultimate from basic which began to caused the problem.
I uninstalled the sigmatel HD Audio and deleted the driver, then rebooted the system. The system automatic downloaded the driver for sigmatel HD Audio. Fixed the problem.
Same problem with audio; same fix disabling modem works.
I have the same problem with a dell inspiron; I reinstalled Vista and the sound is not installed (and frustratingly, I can't turn off the system sounds! - the speaker is functioning well enough for these!)
Disabling the modem and downloading new drivers seems to have repaired the problem. But, hey, Dell, does this mean your customers have a choice of a functioning modem or functioning audio, not both? I hope a fix is in the works!!
"No Audio Output Device Installed"
I noticed that you responded to another user having the problem which I am experiencing after reinstalling VISTA Business: "No Audio Output Device Installed"; however, the link you posted was for XP. Do you know of one for VISTA.
