No Audio running Windows 7 x64 on HP dv6718ca notebook!

Hi,
I've tried a LOT the last few days, but i can't seem to get sound on a dv 6718ca notebook someone gave me. It was running on Vista but i upgraded it to Windows 7 x64.
I'm rather determined to get audio on this thing! Unless it's ABSOLUTELY impossible.
has anyone gotten this setup with audio going?
AMD Turion X2
Nvidia Chipset
Nvidia7150 video
any insights appreciated,
thank you!

well, i've tried the Conexant drivers, getting 'cannot find media device for this driver' and still getting (code 12) error for high definition audio controller in Device Manager.
as one last stab, this is the listing under conflict/sharing tab in MSInfo. I don't really know what should be here, but if anyone here is fluent with IRQ and can spot something, please feel free to comment! thanks:

I am trying to load the 64 bit version of iTunes on to my PC but it continues to fail. My Pc is running Windows XP x64 edition. The rrror message states I need Window Vista 64 or later. What should I do?

I am trying to load the 64 bit version of iTunes on to my PC but it continues to fail. My Pc is running Windows XP x64 edition. The rrror message states I need Window Vista 64 or later. What should I do?

There is no version of iTunes that truly supports the 64-bit version of Windows XP and never will be. If you search this forum for "XP 64" or do a web search for something like "iTunes Windows XP 64", you'll find threads describing the process some people have used to "crowbar" iTunes onto XP 64, with varying levels of success, none of them complete.

I am thinking of buying an Officejet 7610. I am running Windows 7 'x64 bit'.

I am thinking of buying an Officejet x64. I am running Windows 7 'x64 bit'. In the specifications it is stated that the maximum sheet size is 44" (1.01 metres) with Apple Computers, but only 19x13 " with Windows; why is there this difference, and can it be overcome in ANY way please?

I know that the program is old, however it was expensive to buy and I am really familiar with how it works, so that's why I would like to be able to do the cross over.

Can OS X Lion Run Windows 7 x64 Bit?

Hi Guys,
"Can OS X Lion Run Windows 7 x64 Bit?"
- I can see nothing in the bootcamp section that states it must be x32 bit?
... Soooo Yea...
- Dave.

Apple told me to NOT download the Boot Camp driver for Windows using the Boot Camp Assistant application in Mac OS X 10.7 Lion. I was told to download Boot Camp Software Update 3.1 for Windows 64-bit from the Apple website or use the ones that were included on the Mac OS X 10.6 disc providing they were at least version 3.1 and install those. Then I was told to run Apple Software Update to see if there were new Boot Camp drivers available and if there were to download and install them and to then run Apple Software Update to see if there was another version after that and if the was to install that one if not then I had the latest version. I take it that the latest version is 3.2 which was released 18 November 2010 since it didn't tell me about a newer version.

Macbook Pro 15" (early 2011) unable to run Windows 7 x64

Dear Apple Support Community,
I encountered a problem trying to install windows 7 x64 on my MBP.
All the installation steps went well, until the point when I ran Boot Camp 5 (the suggested version for my computer) to install drivers. After the installation of these drivers, I restarted the system. After that, windows 7 booted up nicely and normally, until I selected the user and came to desktop. Then, the screen just suddenly went extremely dark (the machine was still running normally).
I suspect it might has something to do with the graphics driver and reinstalled it several times using different versions of Boot Camp. When I tried to install the Intel HD graphics 3000 driver, it said "your computer does not meet the requirement to install..", which confused me even further 8-}
How could I solve this problem?
p/s: please pardon my poor English.

Welcome to Apple Support Communities
Your MacBook has got two GPUs, and Windows is only using the dedicated GPU, which is the AMD Radeon HD 6490M or AMD Radeon HD 6750M. You have to install the graphic card drivers from the AMD site > http://support.amd.com/us/Pages/AMDSupportHub.aspx
Did you try to set the brightness with the F2 key?

Where can I download HP Recovery Manager for my TouchSmart 610--1150xt running WIndows 7 x64?

Many users would prefer a clean install of Windows with the option to install only those applications that they personally find useful. Currently, if performing a clean install of Windows -- even if creating recovery disks and maintaining the HP recovery partition -- it is not possible to access the Recovery Manager with the option to re-install only the drivers and any useful preinstalled software. The only options under these circumstances is to perform a system restore back to the factory state thus removing an separate clean installation of the operating system or reinstalling the limited number of drivers and applications available for the TouchSmart from HP Support.
If it were possible to reinstall the HP Recovery Manager software, it should also be possible to selectively re-install needed drivers and applications from the recovery partition using the "Software Program Reinstallation" and "Hardware Driver Reinstallation" options. These options are not available from the boot menu or reinstall disks.
I have found downloads for the Recovery Manager software specific for Windows Vista and for certain specific HP laptops running WIndows 7, but I have been unable to locate a similar download for the TouchSmart 610 AIO. Has anyone located a download of the HP Recovery Manager software applicable for the TouchSmart 610?

This procedure uses the original factory installed HP OEM Windows product key and HP OEM certificate and requires the HP BIOS to have SLP/SLIC v2.1. This procedure will install a completely clean Windows 7 installation and may require the installation of HP drivers. Some HP drivers and/or HP software needed by your computer may not install because the OS is no longer branded as "HP". Please create your personal HP Recovery Disc set before continuing with these instructions. Back-up all of your personal data and files before proceeding with this process.
1) Download and unzip ABR Beta for Windows 7. Here is the main page to ABR for Windows Vista. Please follow the "How to use it" section for information and instructions on how to use it. These steps apply to Windows 7 as well. Perform the "activation backup" on your original hard drive with the factory HP OEM Windows installation, saving the backup files in several locations (USB stick, SD card, external drive, etc.).
2) Download your version (the version that was preinstalled on your HP computer) of Windows 7 from Official Windows 7 SP1 ISO from Digital River. Using the built-in Windows 7 CD/DVD burning software, burn the downloaded Windows 7 ISO image to a DVD.
3) Install Windows 7 from your new "Windows 7 disc" to your SSD, following all prompts as needed. Don't enter a Windows product key and don't allow Windows to try to auto-activate. After the Windows installation is complete, run ABR "activation restore" to "install" the previously backed up product key and certificate. Verify that Windows is activated, if not activated... repeat "activation restore" until Windows 7 is activated.

I, personally, have used the above procedure with great success on many HP desktops and laptops. I can't comment on how well it works with HP TouchSmart computers as I haven't had one to experiment on until recently.

I have upgraded to iTunes 10.4 this morning, and now my iTunes toolbar no longer works. I'm running it on a windows 7 x64 machine.

After upgrading my iTunes installation to 10.4 my toolbar has stopped working completely.
The start/stop, back and forward, volume slider and restore buttons do nothing at all when clicked.
They worked perfectly before the upgrade, and I have rebooted/shutdown my machine numerious times and it still doesn't work.
I am running Windows 7 x64 on an HP 8000 Elite (Core Duo E8500 3.16GHz with 8GB)
Any ideas, or is it a code problem???

Well everything works fine for me using 64 bit Windows 7 on a Dell XPS.
I guess you could try a repair install of iTunes to see if that helps. Try disconnecting from the Internet disabling all security software while you do the repair in case something is getting blocked.
If that doesn't work, try another account to see if the problem is account specific. If it is Try the things in the section on user specific problems in this troubleshooting article:

Creative audigy 2 (SB0400) + windows 7 x64 compatability issue.

Hell everyone, I am experiencing an issue with my sound card " the creative audigy 2 (SB0400) model " . I am running running windows 7 x64 bit with all latest security patches and updated drivers where available. However, when using the provided drivers from windows update (WDM), I experience a pause when listening to any type of music files ie: mp3,flac,ogg just to name a few and when playback on several media players, it freezes the sound + mediaplayer for a minute or two, then it will play onward. Also when not playing any media files, I have noticed a crackel pop every so often from my speakers, which can be annoying as well.
Now, I have uninstalled the drivers provided by windows 7 update via " Start button > Computer > Manage " and selected Device Manager Then Sound , Video and Game Controllers and Right clicking on Creative SB Audigy 2 (wdm)? and choosing uninstall making sure the box is checked to also "Delete the driver software for this device" And did a reboot afterwards. After the reboot I have now downloaded the current driver pack from Creative Labs website SBAX_PCDRV_LB_2_8_00. It has installed successfully other than the fact that it has detected a previous driver (by windows updates), which I had " thought " it was deleted by windows 7. Now after i have installed the SBAX_PCDRV_LB_2_8_00 driver, when going to the speaker icon in the windows 7 tray area and selecting sounds I am annoyed by a message box saying: Windows has detected that audio enhancements for the following device are causing problems: Speakers (Createi've SB Audigy 2 (wdm) )? Would you like to disable the Driver Enhancements for this device ?.
First of all, Why would I want to disable the " Driver Enhancements " for my SB0400 card when the card is supported for it. Are these issues be fixed, if so, please point me to the rigth direction for the proper support for my device. ?:angry:
Also, I have been noticeing when playing any type of media file mostly all formats out there the sound will just RANDOMLY stop and freeze.

Wireless issues with MacBook Pro i5 in Boot Camp Windows 7 x64

I have a 2010 Macbook Pro i5 15''. I'm usually connecting to the 802.11n 5Ghz wireless network of my Time Capsule when running OS X, which works absolutely fine. When running Windows 7 x64 in Boot Camp though, this network can't be found and I have to connect to my secondary 802.11g network of an AirPort Express. Even this network connection usually dies after a few minutes of intensive use though (copying files, playing online games; it's fine with low activity like web surfing). It still appears connected normally, but no data is being transmitted. I have to reset the wireless adapter to get it to work again. The same network works fine for any OS X device.
The Windows drivers for the Broadcom chip in this machine seem really flaky. Anybody else have these problems or maybe a solution?

Yes, sorry, the Boot Camp area would have been a better place to ask. After some more googling I found a helpful thread though, which led me to download this driver package:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?swItem= ob-80585-1&lang=en&cc=us&idx=3&mode=4&
From it I installed the driver called "Broadcom 43225 802.11b/g/n", and presto, I can finally use my 802.11n network under Windows. Hope that's helping other people that may have this problem.

Windows 7 x64 ult. update KB2685813 failed on bootcamp 5.1 (MacBook pro retina late 2013)

Hey,
I have a MacBook Pro late 2013 running Windows 7 x64 ultimate with bootcamp 5.1.5640.
Windows failed to update user mode driver framework 1.11 (KB2685813) several times now.
I did even get stuck during instalation after reboot.
I dont want to risk to lose the windows.
What can I do?
Cheers.

Ok, where is this Intel driver? There is no such thing "program manager" so I am guessing you mean the Programs and features control panel, but on my machine that whole window is blank after a clean install. I still cannot get the USB ports to activate. Two fresh installs and several different USB sticks later and no luck. Should I just give up and go to Windows 8.1? I really need Windows 7 to work if at all possible. Other devices shows one USB controller without driver software so I suppose that's the culprit. There are other USB devices installed under the USB section of Device Manager, but they apparently have nothing to do with the USB ports themselves, just devices like the trackpad etc. I've spent two hours on this so far and it's getting out of control. Why doesn't this work with generic USB drivers?

ITunes 9.2.1 doesn't see my iPhone 3G 4.0 on Windows 7 x64

Hi everyone. I'm running Windows 7 x64 and have been having this problem since I updated my iTunes to 9.2. The problem is I plug my phone in, and iTunes doesn't see it. After plugging it in, iTunes seems to struggle a bit, lags, before finally running smoothly again. The phone doesn't appear in iTunes, though my computer detects it and I can browse the photos like I always could. Any help is appreciated!

yup same here
its a crapshoot, sometimes it happens other times it does not
only way round this i found is to do this:
reboot windows
and reboot iphone
eventually they will see each other.
what causes it? poorly coded itunes for windows, who knows.
but its something i've had for many versions now, 9.2.1 is nothing new. but it does seem to happen more now.

HP PhotoSmart C4599 problems with Wireless on Windows 7 x64

Verify that power outlet is working with a lamp or other appliance.
Verify power cord and power module are correct parts for that specific printer. Compare the Output voltage on the power module (the black box) with the listed voltage on the printer where the power cord plugs in. These must be the same
Remove power cord and power module from printer and power outlet. Separate power cord and module (let stand for 15 seconds)
Plug Power Cord into Power Module (plug firmly together)
Plug Power Cord with module directly into WALL outlet (Remove any surge protector or extension cords and plug printer cord directly into wall socket)
Check to see if power cord or module has LED light.
If has LED make sure it is glowing (if not glowing then replace power cord and module)
If no LED Plug cord into printer - make sure it is plugged in properly and firmly.
Press power button on printer to power up. If does not power up first time hit power button a few times to see if it works.
if you happen to have another printer with same power cord configuration (fits specs) try these steps again
If printer will not become responsive at this point, then you'll need to replace the printer.
if it is a hardware issue, contact HP support at 1-800-474-6836. Often there are special offers on replacements available to returning customers who are having hardware issues.

Windows Update on Windows 7 (x64) on boot camp fails

Running Windows 7 x64 on Boot Camp and trying to install an "important" update from windows update, but it fails:
Update for Windows 7 for x64-based Systems (KB2506014) - Published: 4/12/2011.
I received error code 80073712 and ran System Update Readiness Tool to no avail. Microsoft recommends repairing Windows from the install disc if using that tool fails, but I'm not willing to go that far just yet.
KB 2506014 title is "Update for the Windows Operating System Loader", so I am wondering if there is something about how Boot Camp is configured that is preventing this from installing.
Has anyone else running Windows 7 x64 on Boot Camp received the same error for this particular update, or been successful in installing it? It is thus far the only windows update that has failed to install for me.

Bootcamp WIndows 7 x64 and Syncmaster 204b external monitor

Hi,
I didn't see a sub-forum for external monitors so I hope the Firmware forum is ok since this seems like a drivers/graphics card issue issue.
The issue I'm having is that Mac OS crashes randomly when I connect my external Samsung Syncmaster 204b monitor to my Macbook Pro when running Windows 7 x64 under Bootcamp. The external monitor turns yellow and the Macbook LCD turns gray and I'm forced to do a hard-reboot. Windows does detect the monitor and I can see it with it's correct name under Windows Display Properties.
Everything works fine when I run the monitor under Mac OS 10.6.4.
I'm running Windows 7 x64 on a mid-2010 Macbook Pro 13". I have all of the latest updates installed for Windows and am using Bootcamp 3.1.
Has anyone encountered a similar issue or have any ideas how this may be resolved?
Thanks, -Scott
Message was edited by: Scott Cullen

Ok, I think this problem has been resolved, so I'll post the solution in case others with the Samsung Syncmaster 204B have the same problem. The answer was erasing the PRAM by holding Option-Command-P-R at boot up (http://support.apple.com/kb/ht1379).
This is what I think happened:
An update in Windows Update is available for the Syncmaster 204B, but wasn't visible when I first connected the Syncmaster. I wasn't able to see the update until I rebooted with the Syncmaster connected (after several crashes). After seeing the update in Windows Update under 'Optional Updates", called "Samsung - Display- 204T/204Ts/204B, Syncmaster Magic CX20Ts(digital)", I installed it, but bootcamp Windows continued to crash randomly after attaching the Syncmaster via both Mini Display Port-to-DVI and Mini Display Port-to-VGA. Sometimes it crashed after a few minutes, sometimes an hour, the same as before I installed the update.
I was convinced that it was a compatibility problem between Windows 7 x64, the Syncmaster 204B and the MacBook Pro 13" Mid-2010 hardware since this problem only happened when booting into bootcamp Windows 7 x64 (everything worked fine in Mac OS), but now that doesn't seem to be the case. I think the update fixed the problem, but after installing the update some of the of the original incompatible display settings remained resident in the Mac's PRAM. Erasing the PRAM cleared these settings and allowed the new updated settings to be loaded instead, fixing the crash issue.
