Upgraded window from vista to 7 on pavilion DV7 sound not working

Pavilion DV7 1468NR upgraded windows from vista 64 to windows 7 64 sound not working

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp45001-45500/sp45073.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services. Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type', select Automatic and click Apply to save the change. Then click the Start button.

DP-K

Go to the link below.Enter your Product Number as listed on Service Tag attached to bottom of notebook (may be under battery). You can also get the Product Number by pressing Fn + Esc key. After entering PN, click Next ,then choose Software & Drivers.On the next page use the dropdown to select your OS (probably Windows 7 64bit). A list will populate with drivers. Download & Save the latest Audio driver.

Go to Control Panel,Programs & Features-Uninstall IDT software and restart the laptop.Next install using the downloaded file.

If still no sound,try a hard reset, works sometimes.Disconnect all external devices first.
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall only power cord for first startup.
4-power on

Quicklaunge buttons on my HP Pavilion dv7-2260ed not working and always red

The quicklaungebuttons (Mute, Volume, cd options and wireless) on my HP Pavilion dv7-2260ed stopped working and are always red. This happend 3 weeks ago. I runned the HP assistent but no errors were found. Any help is welcome

Hi, I have more or less exactly the same problem.
I own a pavilion dv7 1090eb, which originally had Vista 32bit on it, but I updated to Windows 7 32bit more than a year ago,
not long after 7 was released. Ever since that update (or a few days after, I don't really remember) I've been having problems with the quick launch buttons.
For over a year it was just my mute button that was always orange. I could still mute my sound, but when not muted, it sounded like it was really filtered, all the low and the high were gone, only low mid sounds remained.
My jack exits, both of them, however, still work fine, and I have good audio through external speakers, so I kind of solved that.
But still, the laptop itself has great sound, so I should be able to get that without having to carry around external speakers wherever I go.
Oh and I used to have the same problem with Vista from time to time, but after rebooting it would just go back to normal.
But now just today, I left my laptop on for about 2 hours for some image rendering while I was away, and I switched the wifi off, which I usually do when I leave my laptop unattended. But when I came back, it wouldn't turn back on again, and none of the quick launch buttons worked anymore.
I tried reinstalling all drivers after I did some troubleshooting options which didn't work.
Turned it off and on again a couple of times.
Then found this thread and installed the above link, rebooted, still doesn't work.
What now? What can I do to resolve this problem?
I really hope I can get a solution for this.

Upgrading Windows from Windows XP to Windows 7

Dear Sirs,
My company is upgrading windows from Windows XP to Windows 7 in clients' computer. We have found that an application which had been developed by vb .net (framework 1.0/1.1) has a problem when printing report (crystal report 9.0). An error "query engine error......" will throw during printing.
We have already setup the crystal report 9.0 runtime in the client's computer. However, the problem still exists. I have read some similar problem on web and I know that it should be the engine problem when fetching data from dataset to rpt file. Currently the version of crdb_adoplus.dll is 9.1.0.24 (not 9.1.0.30) for the crystal report runtime.
Although I have known the problem, I cannot find an exact solution for the case........may you suggest a configuration/setup step for solving the case?
Thank you very much.
All the Best,
Albert

Hi, thanks a lot for your help again.
I have tried to setup the crystal report 9.2 runtime (downloaded from http://www.randem.com/crsupport.html) and it works. However, I am not sure if it is a valid way to do so. Is that SAP does not provide such runtime? (I can just find the merge modules for crystal report 9 and I don't know how to work on it.....)
Thanks a lot.

Hey rudreshchoubey,
Thanks for the question. The following resource may help to resolve your issue:
Boot Camp Installation & Setup Guide
http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf
If Windows doesn’t install properly
Verify that you’re using an original, full version of the 64-bit version of Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, Windows 8, or Windows 8 Pro.
Restart your Mac and hold down the Option key until one or more disk icons appear on your screen. Insert the Windows installation disc into the optical drive or insert the USB flash drive with Windows into a USB port on your Mac. Select the Windows installation disk icon, then click the arrow beneath it. Quickly press any key on your keyboard to start the installer. Follow the onscreen instructions to repair or reinstall Windows.

Sound not working in windows vista using bootcamp

hello everyone,
i recently installed vista on my imac 24in 2.4ghz 4gb ram and the sounds not working. searched google and this came up.
http://answers.yahoo.com/question/index?qid=20081023034326AAhBL2A
they gave a few options but i dont seem to fined a driver. my device manager says its fine. ive looked in thw volume settings and its turned on. i dont know what to do now.
any suggestions? thanks

Hey Manuel,
I myself had the same issue, no sound and nothing indicating a problem. Insert your apple disc and click repair, reinstalls all the drivers, this fixed it for me, although I had several other drivers fail some weeks later, so started from scratch and been good for a month or so

AUDIODG.EXE hogging 80-100% of CPU and sound not working in Vista . . .

I posted this on a Microsoft Answers Forum but none of the techs or people reading have been able to help so far. I'm dying to get to the bottom of this:
Here is my computer:
MSI K8N Neo4 Platinum
AMD Athlon 64 3000+
2GB RAM
XFX GEFORCE 6600 GT 128MB DDR3 DUAL DVI & TV OUT (PCI-E)
200GB WD SATA HDD
500GB WD HDD in external enclosure via USB2
NEC ND-3520A 16X DVD±RW Dual Layer DVD Burner
LG CD Burner
I've been using Vista Home Premium successfully for some time. Recently, not too long after I did a clean wipe of my OS, my audio would stop working. The way it would happen is that everything would work fine until I started iTunes or another audio application and when I would hit play, things would lock up.
Upon inspection of my system resources, I'm noticing that the audio platform for Vista, via the audiodg.exe, is using close to 100% of my CPU resources, even when the computer is making no sound at all.
I've had a Sound Blaster Live! card in my computer for some time but I was not using it; I use the Realtek AC'97 audio drivers that are on my motherboard instead. I thought that the conflict may be the computer wanting to recognize my Sound Blaster, so I took it out of my computer but the problem seems to be worse.
Are there any BIOS setting that need to be adjusted for my sound to start working again?
I'm very reliant on the audio processing power of my computer (I'm in the radio industry, part-time) and this is a huge drag on my productivity.
Any tips would be much appreciated.
REPLY #1:
Thank you for using Microsoft Answers forum. I suggest going to the manufacture of your sound card and download the latest drivers and install them.
MY RESPONSE:
Good suggestion. The problem is this:
I am running on-board audio. I have an MSI K8N Neo4 Platinum motherboard which runs "Realtek ALC Series AC97 Audio Driver" and there is no version for Vista. They have a version for Windows 2K/XP and one for Windows XP 64bit.
Should I use on of those and if not, then what?
UPDATE (from me):
I took a chance and found a Realtek AC'97 driver for Vista.
http://drivers.softpedia.com/progDownload/Realtek-AC-97-Audio-Codec-Driver-Vista-6183-Beta-Download-18114.html
I went to install it and the install hung. So, I closed one of the install windows and then the InstallShield app continued like it was working. So, I hit "Restart my computer". Well, the reboot hung too. So, I reset the PC manually.
When the computer came back up, the sound worked. Hard to tell if this will fix it for good but it's promising. Chaotic. Unpredictable. Annoying.
REPLY #2:
Before you tried updating drivers, did you try rebooting 1st?
I'm just trying to determine if rebooting your system is what resolved the issue - thank you
UPDATE II (from me):
My computer is behaving the same way it was before. AUDIODG.EXE taking up 80-100% of my CPU and the sound not working.
Any other ideas?

Small update: Despite my intelligence, good looks and vast experience I use Google sometimes. To my surprise this file turns out to be a Windows one. Here is someone who is much happier, and since it is some way in my line of thinking I'll quote it, but you might take my previous advice as well:
http://forums.techarena.in/windows-vista-performance/1012315.htm
"- Open up msconfig.exe > Manage startup programs.
- Disable ALL Realtek entries
- Close msconfig.exe
- Right-click on the speaker icon > Audio devices > Speakers (properties)
- Go to the enhancements tab
- Check the box to disable all audio enhancements
- Close the menu
- Right-click on the speaker icon > Recording devices
- Disable all your microphones (yeah..., the actual problem seems to come
from voice inputs rendering..)
- Close the menu
- Restart your computer"

HT3180 I owned an Apple tv and after upgrade my internet to higher speed my Apple Tv does not work the only message that show on the screen said if time and dates are not found go to apple/support/tv tried almost everything and nothing. Please somebody

In most scenarios you shouldn't need to forward ports, however if you need to, you may be best contacting your ISP.
As with most router issues, I would recommend that you contact your ISP with details of your problem (assuming that it was your ISP that provided it to you).
There are simply too many manufacturers with different software features and settings and often different names for such features and settings, that the best advice will likely come from those that are knowledgeable about your particular router.
Make sure your router/computer allows access over the following ports

After upgrading to OS 10.8, my Mac App Store is not working. It says: Cannot Connect To The App Store

After upgrading to OS 10.8, my Mac App Store is not working. It says: Cannot Connect To The App Store. Kindly Help

Also having that problem - I checked and I am connected to internet (can access other websites or other pages in Apple's website), can login from Snow Leopard (10.6.8) with Mac App Store there, but if I use the (external) drive with ML to start up, no go.
I can get to the "Featured"/initial MAS page, and tried going to the login from there, but same problem as Mitoshacer.
In my case, MacBook Pro (2.66GHz, 8GB RAM, 500GB external with ML - vs. 320GB internal drive with 10.6.8), March/April 2009 model. Have done searches for the problem online, but nothing shows up (except some for older OS X versions).

HT201304 I can't install any app from apple store. The install button is not working now. Before it was working perfectly had installed many app and I had purchased many app from i-store

If you installed Leopard that is why you can't install Mt Lion. The system Must be running Snow Leopard 10.6.8 to upgrade to Lion or Mt Lion.
If you only erased the Macintosh HD partition then you left the Mt Lion Recovery HD partition in tact on that system. At startup hold down the Command+r keys to boot to the Recovery HD Partition. From there erase the Macintosh HD partition and then select Reinstall Mac OS X. It should then download Mt Lion and ask you for the Apple ID that was used to purchase Mt Lion.
The Reason Snow Leopard might not be installing is because of the Recovery HD partition. To get rid of that you must First Re-Partition the drive As One Partition. Then install Leopard then SL (Or Snow Leopard from the start) and then update it to 10.6.8. Once that is done you should be able to log on to the Mac App Store and Re-Download Mt Lion.

TS3276 I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone

I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone help?

Thank you for heading me in the right direction. I reset my Mail account for Outgoing Mail Server to outbound.att.net:(customer ID)@att.net (instead of smtp.att.yahoo.com, per Apple's online troubleshooting information). I'm not sure what "(Offline)" means when it appears at the end of my Outgoing Mail Server (SMTP)?? In the Advanced box I clicked on "Use custom port: 465" and checked "Use Secure Sockets Layer." Authentication: Password; I have correct User Name and Password put in. After doing all this, when I try to send emails again today, they go directly to the Outbox and sit there.
What's curious is that my first sent email this morning did go out using the Outgoing Mail Server, smtp.att.yahoo.com: (customer ID)@att.net(Offline) but subsequent emails I tried to send with this server were rejected with the message: "Cannot send message using the server smtp.att.yahoo.com (etc.). The SMTP server doesn't support TLS(SSL) on port 587. Verify your account settings and try again." That's when I tried resetting my Outgoing Mail Server to outbound.att.net (etc.), as mentioned above, and was unsuccessful in sending out any further emails. I guess my next step is to contact my email service provider, AT&T, and see if they can help me. Thanks, again, for taking the time to respond and for giving me your input! Much appreciated!
