No Sound after Bootcamp 3.0 drivers

Just installed Bootcamp 3.0 drivers from the Snow Leopard disk, and now have no sound.
During the install process there were lots of references to Sigmatel, which is what I think the driver used to be, but in Deice Manager the sound driver is now IDT which also has a menu bar icon bottom right.
Any ideas?
Thanks

I have "solved" this by installing just the Bootcamp 2.1 sound driver from here:
http://files.geoffgarside.co.uk/bootcamp/Drivers/IDT%20SigmaTel/
The original problem is that with 3.0 there was no sound from the internal speakers on my MBP...only from the headphone jack where the optical output red light also showed. I could not find anyway of making it play through the speakers.
Would still be grateful for any proper resolution of how to make the BC 3 sound driver work.
Thanks

No sound after installing the latest drivers

After installing the latest drivers for X-fi xtrememusic, 2.8.003 I have no sound. Also my creative console is stuck in Entertainment Mode, it won't switch to any other mode. Help please?

Well, i don't have a solution for you, but if your soundcard + hub act like that even under xp after a few weeks i would suggest to get a replacement, cause there might be a hardware-error that causes your problem. A software/driver problem sounds very unlikely to me. That your having problems under Vista, isn't strange at all, cause there are still no final drivers relaesed for Vista and the support of the hub is rather barebone at the moment. Stormblade

Audigy 2 - No Sound after reinstall with latest drivers

I have reinstalled my harddri've and as part of that had to reinstall my soundcard (Audigy2). This is an old Dell system for the kids to play around with. However I can't get it to work. Initially the Audio console kept defaulting to Headphones. I have clicked off the sync with Windows and now both are on 5., but still no sound.
No conflicts or anything, speakers are connected (and always worked well before this), not set to digital output,
Any idea anybody?

PieterVL,
Is this a Dell OEM card? Do you have an installation CD for it's If so, did you cancel out of installing the Windows driver and install the driver from the CD?

Problems with Bluetooth stack after bootcamp driver installation.

I have been running Windows Server 2008 in bootcamp without drivers from the Mac OSX installation cd for a few months with everything except soundcard and function keys working - but since I have found that I need sound and the function keys, I decided to install the Bootcamp drivers and all other drivers that my system would recognize and use.
At this point I should say that ever since I installed Windows Sever 2008, I've been using a mighty mouse wireless on both osx and server 2008, and both have been working perfectly both running natively (in bootcamp or osx) or in virtualization (with vmware fusion on osx).
After completing said install, I rebooted and found to my horror that my mighty mouse wireless had stopped working. I went into the control panel of server 2008 and found the bluetooth.cpl and proceeded to correctly find the mouse identified as it was setup in osx when I first set it up there. I then tried connecting to it in multiple ways, both by supplying no passphrase, letting it decide it's passphrase or entering one (0000 as some documentations have pointed out). None of these solutions worked, so now I'm stuck with a mouse that works in osx and vmware fusion, and that used to work in server 2008 before I installed Apples provided drivers for their hardware.
So my question is - have any of you run into this problem on Vista (I'm figuring Vista is closer to server 2008 than XP is, because they share at least some of the same core as far as I know).
Another thing I've noticed is that I can't make Apple Software Update update Bootcamp to 2.1 - it simply doesn't acknowledge that Bootcamp is installed on Windows, even if I try and force the registering of it with the encluded .exe file in the zip when I download it manually)
I would really appreciate any sort of help on this problem, as I'm fresh out of ideas as to what I can do about it. The only thing I can think of is that Apple's drivers somehow broke the configuration that was working (in resetting it after reboot), but then the question is: How to make it work again.
Again: please help, any help is much appreciated.

Today I installed Vista Ultimate on my new (early 2008) MBP, to find that it killed my Bluetooth on Vista, and also on my OS X partition. Both OS's claim that there is no Bluetooth Hardware attached. It worked after I installed the Drivers, but stopped when I tried to install an Apple BT Keyboard.
Any assistance would be greatly appreciated. I'll begin searching for an answer.
I did do a Super Duper Clone, before I installed Vista on the Boot Camp partition, but I'm fearful that it may be a hardware issue.

No sound after upgrading to Windows 7 M55-S3293

I upgraded to Windows 7 and installed the drivers from Toshiba for my sound card and before installing checked the windows XP box under the compatibility tab. No sound. I did windows update for this driver and it installed an updated driver. No sound. I went to Realtek and installed the windows 7 generic driver for this sound card (thats all manufacturer's offer is a generic driver) and LOW sound. Now I rebooted and back to No sound.
Before windows 7 sound, after no sound.
Toshiba put out a fix for a contextant audio driver for the low sound problem to be corrected with windows 7 but I cannot find anything for my computer.
I don't know know what to do! I don't want to go back to using XP but sound is REALLY important. I would think this is an integrated sound card (Toshiba isn't making service manuals public anymore, it was there the other day and gone today) so I cannot remove it. I don't think I have any available PCI slots to install a new one internally and I don't want extrenal speakers since I do a lot of traveling.
Is there a fix I don't know about? What can I do? Please HELP!!!

Hi Ryan,
Go here: http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/downloadDetail.jsp?soid=1671893&pf=true
and download the software called "Sound Utility to Turn Mute Off After Upgrading to Vista", it is made for people that upgrade to VISTA, however, once you have all your Toshiba updates installed by downloading the Toshiba updates, then apply this update to your Windows7 system and the problem will resolve.
I don't know why they did not make this update part of the Toshiba Update Package.
I hope this helps,
best,
Alejandro

HP pavilion dv6000 with windows 7 64 bit has no sound after disassembled.

Hello there,
I have an HP Pavilion dv6000 and after i disassembled and reassembled it to clean the fan, the lap top has no sound. In the device manager an error on ''PCI bus9, Device 9, function 2 & 3'' was appeared but after i installed new drivers the errors was fixed and it was written that the device was working properly. but unfortunately the device is not working properly because i stills have no sound. I also disassembled and reassembled for second time to find out if the problem was minor like an unplugged cable but everything was completely fine. Operation system: Windows 7 64 bit. Can someone please tell me what to do?

Bootcamp no device drivers found (Windows 7 64-bit)

Hello,
I am desperately trying to install Windows 7 64-bit on my mid-2011 MacBook Pro, on a 100g partition made by Bootcamp.
My Macbook is using the latest Mavericks update OSX.
I am using a Windows 7 .iso trial downloaded from Microsoft DigitalRiver and am using the Bootcamp 5.1.5621, as advised by Apple staff on this website.os
I have an official and working Microsoft Windows activation code with which to activate the trial, once installed.
However, first of all, Bootcamp 5.1 fails to recognize the .iso file. So I burned the .iso to a DVD. I have downloaded the latest Bootcamp Windows Support drivers (as said, 5.1.5621) onto a fully functional and accessible USB drive, which is MS-DOS FAT formatted and inserted in the USB port the whole time.
Now Bootcamp detects Windows 7 on the DVD and starts the installation procedure. Macbook resets, Windows starts installing.
And then, after selecting language and OK'ing 'Install', I get the dreaded Windows Explorer screen informing me that 'No device driver has been found'. In the directories on the USB, I flip through all the files but no .exe or other executables are encountered.
As far as I can see, I'm doing everything by the book. So why isn't the book working?
Looking forward to your advice.

1. The USB needs to be USB2 not USB3.
2. From Boot Camp: System requirements for Microsoft Windows operating systems
Requirements for all Windows installations
In order to install Microsoft Windows using Boot Camp, you need the following:
An Internet connection
An administrator account in OS X to use Boot Camp Assistant
The keyboard and mouse or trackpad that came with your Mac (If they aren’t available, use a USB keyboard and mouse)
A minimum of 2 GB of RAM, 30 GB of free disk space are recommended if you are installing Windows for the first time, or 40 GB of free disk space if you are upgrading from a previous version of Windows
An authentic Microsoft Windows full install disc or ISO file
A built-in optical drive, or a compatible external optical drive is required if you are using an install disc
8 GB USB storage device, or external drive formatted as MS-DOS (FAT) to install the downloaded drivers
3. From Boot Camp 5.1: Frequently asked questions
Can I use a downloaded (ISO) version of Windows with Boot Camp?
MacBook Air (Mid 2011 and later), MacBook Pro (Mid 2012 and later, including Retina models), Mac mini (Mid 2011 and later), and iMac (Late 2012) can install downloaded (ISO) versions of Windows 7 and 8.

How are Bootcamp 5.0 drivers working on Windows 7 64-bit?

Hello,
I was wondering how the Windows 7 64-bit Bootcamp 5.0 Drivers are behaving. In this forum, I have read reports about the internal keyboard in MacBook Pros failing after installing the 5.0 drivers. A case like this is referenced in the forum post below:
No wired USB Apple-keyboard or USB-Mouse found under W7 64bit after Bootcamp drivers 5.0.5033
Could this be only a one-time issue? or I am planning to install Windows 7 on my MacBook Pro since installing OS X Mountain Lion 10.8 back in July. You can say procracination took over.
Many thanks in advance for your assistance!

You're trying to use a 32 bit Oracle Client with 64 bit SQL Developer.
You're doing something in SQL Developer that's requiring us to load OCI - in your connection properties, use Network Alias instead of Connect Identifier for TNS, or make sure in your Advanced settings you don't have 'Use OCI/Thick driver' enabled.
Or, install a 64 bit copy of the Oracle Client and tell SQL Developer to use that home instead.

No sound under bootcamp XP SP3

I just installed Windows XP SP2 and updated it to SP3 under bootcamp. I did the bootcamp 2.1 update, and installed the drivers from the leopard disk. However, I still have no sound, either in my headphones or in the built-in speakers. Any help would be greatly appreciated

I've got the same problem but my imac is running SP2.
I get a yellow "!" on one of my PCI sound devices but updating the drivers or trying to activate it will not work. it says that the device is working correctly however "it is possible that another program is running" so making the device not working properly.
the thing is. yesterday when I shut down the mac. everything was working fine. the sound was coming out of the speaker perfectly.
I did try to tweak something though, trying to fix my microphone problem, So I guess i'm the problem but now there seem to be no way of fixing this.
I tried reinstalling all drivers from the mac CD but nothing works. please help

No sound since I installed new drivers

I installed some newer drivers on my Li've! 24 bit sound card. Now I've lost all sound, I tried rolling back the drivers, still no sound. So I've downloaded the drivers 4 separate times now, still no sound. These are the drivers I installed.
Creative Sound Blaster Li've! 24-bit and Sound Blaster Audigy LS driver .04.0055 (.9 MB)

So what do I do now? Can I uninstall the drivers? I'm worried if I do that will cause an error of some type, but frankly that's about all I can think to do. Should I try it, or try something else.
HELP!!!

Have you checked if there is some setting left ON (digital playback, muted channel(s), etc.) after installation?
Also,
- did you got some errer messages while installing?
- try re-install the update by running the ctzapxx.exe --> see the installer settings from -->

No sound after installing windows 7 on HP Pavilion dv1710us Notebook PC

I recently helped my uncle install windows 7 on his HP Pavilion dv1710us Notebook PC
and there was no sound after installation.. i downloaded several drivers for the realtek high definition audio driver (R2.39, 38, 37, etc)
then i tried the original driver from the HP drivers page and installed it.
usually when there is no sound, there would be a red X on the volume icon, but when i installed the original driver from the HP drivers page, there was no more red X.. Thinking that the sound was fixed, I tried to go on youtube and watch a video... i see the green bar moving up and down on the volume slide, but then i can't hear anything.
So is there any realtek high definition audio driver compatible for windows 7 on the HP pavilion dv1710us?
Is there something I have to do, like right click on the application and then change compatibility settings?
thanks in advance.

I got it to work with windows 7 32 bit. I just went to hp website to support and downloads section. Type in your model number, then select windows xp as the operating system. Then download the audio driver and save it to your desktop. After the file is on your desktop you need to right click on it and click properties, then go to compatability tab and tell it to install as windows xp service pack 3. Hit apply then install. Hope it works for ya, worked for me.

Lack of sound after Window 7 (64) installation into iMac OX 10.6.7. Tried to install driver from Snow Lepard disc (Cirrus 64).Wizard installed driver. No sound, Device Manager indicated that "driver is not installed" but also that the"device is working"

I don't know how to proceed. I didn't have sound after installing Windows 7 inot iMac OX 10.6.7 (64bit) After unsuccessful attempt to upgrade the driver from the BootCamp file, I deleted the driver from the Sound and Game controlled hoping that I would allow me to automatically install the correct driver from Boot camp.
Now the Sound Video Game controller disappeared from the Device Manager
How can I find out which is the correct sound driver for my computer (The Speaker Properties only say:WIndows)?
How can I install it without seing the Sound and Game controller in the Device Manager?

When you say "manually download", you mean from the BootCamp File on Snow Leopard, or from the Internet.
My additional problem is that the "Sound and Video Game Controller" disappeared from the Device Manager when I removed the previous driver. I don't find the place where I can reistall the new driver.

[SOLVED] Lost Sound After Upgrade

Solved (for now at least). The problem appears to be a bug with alsa. Alsaconf writes a file called /etc/modprobe.d/50-sound.conf, which contains the aliases for the sound card. But for some reason it then wasn't reading the file. Copying the alias entries to /etc/modprobe.d/modprobe.conf to read directly from there seems to have worked.
Now to fix the frequency scaling.
===================== solved ===========================
I lost all sound after the last upgrade. I just rebooted because frequency scaling is also not working, and no sound.

I tried firefox, xine, mythfrontend, avidemux2, xmms and mpg123 - there's no sound in any app. If I play something where there are indicators, like in xmms, the eq indicator levels jump, the song progresses like it's playing, but no sound. I reran alsaconf, it seems to be configured properly. The mixer sliders work and aren't muted. It doesn't work either as root or as user.
I have another computer hooked up through the line out and the sound still works fine there, so it doesn't appear to be a hardware problem.
I'm completely stumped at this point. If it's a bug somewhere, what's it a bug in to cause global sound loss? Is there anything else I'm overlooking? All I can think is that it must be muted somewhere, but I can't find it. Or else it has something to do with the cpu and cpu freq scaling that's also broken now.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

Hi buddy,
Have you already checked the Toshiba website itself?
