Dell Precision T5400 Drivers Download With the 2 XP laptops, all After installing it without a hitch, i can’t get any USB device to work other than my wireless precsion and mouse set made by Acer. Get drivers and downloads for your Dell Precision T5400. Download and install the latest drivers, firmware and software. I have a Dell Precision T5400 workstation that was recently upgraded to Windows 7 64. Since the upgrade, I'm unable to use my audio card. I've downloaded and installed the latest drivers from Creative.

When i go to the device mananger it says that everything is functioning properly. What should i do??

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. Thanks, tbarron7!

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! 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!! 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! 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. 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. 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: (If that doesn't get it done, then the sound card may be toast.) Hope this helps. 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.
