No Sound device on HP Pavilion dv9700

Hello, I am checking out a notebook computer for a friend...
He sent to a technician because his hard drive had crashed, don't know why he didn't send it to me in the first place.
The tech replaced it and installed Windows 7 32bit, but there was no sound, no webcam and the DVD drive was not visible in the OS. I tried to install the 32bit audio vista drivers from HP's website (tried both Conexant and Realtek, and the older ones also) but it kept giving me the error: "Driver installation failed: Could not find the device for this driver"
Since the computer had 4GB of memory, I reinstalled it with Windows Vista Ultimate SP2 64bit.
The reason for Vista is because I know I had experiences in the past where these machines are sensitive when it comes to drivers, especially the audio.
But I kept getting the same error, you do not even see the devices in the device manager.
I also installed the Microsoft UAA...
I still cannot see the DVD drive (you can eject the drive manually using the hardware button)
Also the webcam is also not recognized...
I even tried a hard reset (removed battery, held the power button for 30 secs.)
Now the the last tech. who checked the machine seemed to have opened it up, for what reason I do not know because the hard disks are accessibly in the back through a small panel.
Anyone has any ideas?
Here is the system details:
HP Pavilion dv9700
Model: dv9925nr
P/N: FE695UA#ABA

did you check hardware in bios? if all setting OK, i guess you have hardware problem.

Audio/Sound Devices

I have accidentally deleted my Audio/Sound devices on my Pavilion Dv4-1413TX. Now, I am not able to hear any sound from my com. It says that I have to install some kind of devices, and I'm not sure. Can anyone help me, please?

Hi,
The easiest way to solve this may be to run Windows System Restore. If you have Norton Internet Security installed, you will need to disable Nortons Tamper Protection as shown in Step 2, on the link below.
http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20091112171719EN&ln=en_US
Once you've done this, shut down the PC. Windows System Restore is usaully best run in Safe Mode. Tap away at f8 as you start the PC to enter Windows Recovery Console. Use the arrow keys to select Safe Mode and hit enter. When this has loaded, from the Start Menu, click All Programs, click Accessories, click System Tools and launch System Restore. Pick a restore point before the Audio Driver was deleted and then proceed with the restore process. When complete, Windows will reboot as normal.

Pavilion dv9700 DVD/CD ROM stopped working: Code 10 (This device cannot start.)

I have a HP Pavilion dv9700 running Windows 7 where the DV)D/CD ROM drive fails to be detected. I can still get it to open and close. The device manager gives an error: Code 10 (This device cannot start). I read somewhere that iTunes upgrades can cause DVD problems in HPs, and I did upgrade iTunes a couple of days ago. I did upgrade the BIOS a few moments ago, but it didn't help. Thank you in advance for any help you can provide.

Thank you for the responses! Sorry it took me so long to implement--I wanted to back everything up first before messing with the registry. Following the instructions to delete lines in the registry AND uninstalling iTunes allowed for the DVD/CD ROM to pop up with an exclamation mark in my Device Manager. Updating the driver did not help as the computer said the driver was up-to-date. Mysteriously, when I rebooted, the DVD/CD ROM disappeared from the device manager again. I forgot to mention in the initial post that the DVD/CD ROM light blinks steadily at about two blinks/second. Any other ideas? I am wondering if this is a hardware failure now.

No sound Device detected on HP Pavilion m7650n

Yesterday, when I logged on to one of my sons' computers - there was no sound coming out of the speackes on the HP w22 monitor. I checked to make sure it was plugged in and it was. According to one of my sons, the problem occurred a couple of weeks ago.

No OS Found on HP Pavilion dv9700 issue....

Hello, I'm having an issue...but first here are the specs:
HP Pavilion dv9700 (2008)
Vista OS
Error: No OS Found
No changes, has been having trouble for a few months, have done a recovery twice, it gets hot, which I understand is an issue with this model. My husband was working a Word doc and he backspaced to correct an error, got the 'thinking' spinning icon for a long time, then it just shut down.
The cd drive hasn't worked in a long time so no way to backup or create a recovery disc or even install one if I had one.
What I've done:
nothing but the F10 System Setup works on startup
entered Setup, ran diagnostics: Diagnostics not supported, No IDE device
entered BIOS: changed boot order thinking that the cd drive was causing Boot issues, nothing changed.
did a hard re-set: nothing
removed hard drive and re-seated it, nothing.
So, at this point I'm thinking it's the hard drive. Here are my questions:
Will I need to reload a OS?
If so, how, given the cd drive doesn't work?
There is a space for a second hard drive, if I put the new drive in that space, any chance I can recover anything from the first drive?
Is it even worth replacing the hard drive?
Anything I'm not thinking of?
Thanks so much,
Jean

I understand that your system does not boot and states there is no OS found.
First, verify that all USB devices are disconnected if any are. This can trigger that message.
Verify the missing HDD message by using HP's diagnostics instead. This should be accessible by turning the system on and pressing F2 about once a second.
It does appear that the HDD has failed based on the symptoms, but you could also try reseating the HDD.
If it has failed, a new HDD will be blank. You will need the HP recovery disks to reinstall Windows. I take it you had not made the recovery disks from the system when you first got it since you did check for their availability. To be absolutely certain they are not available, I would contact HP to verify their status. The HDD will need to be at least the same capacity or higher for the recovery disks to work in most cases.
If the HDD has not failed completely, you might be able to connect it to a different system as a second drive to browse and copy files. You might need a USB HDD converter kit to accomplish this. For me, I just connected a failed HDD using the SATA connections and left the HDD sitting loose in the HDD bay;however, this isn't a best practice.
The recovery disks made from a different system will not work on another system as they are tied to the original system. You would get a message about them not being for that system.

Cd/dvd wont read on HP Pavilion dv9700 notebook

HP Pavilion dv9700 entertainment notebook PC won't read any cd or dvd in the drive, but it does spin. PC is running Windows Vista Home Premium SP 2. It does not given an error message. It just stopped working and it is no longer under warranty. Can anyone help get it going?

Hi,
First, try the automated fixit from Microsoft on the link below.
Vista
Check if the drive is now working.
If it still doesn't work, click the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, click the Start Menu, open the Control Panel and click on Device Manager. Next click to open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked. When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ). Let windows reinstall the drive and see if it now works.

Internal microphone in Pavilion dv9700 ?

My control panel the sound device states the microphone is not plugged in. Is there an internal mike? If so how to turn on? or do I need an external mike?

I'm running into a similar issue. I have Pavilion dv6000 and I recently upgraded to Windows 7 and my internal mic isn't working either. I have downloaded the most recent driver from Realtek and still no luck. The system shows it is working correctly, however when i test by recording using accessories recorder and skype - i get a message stating the computer cannot hear me. first I heard static when using the mic now after updating driver, no static, but still no mic.
I have been unable to figure out what is wrong. HP doesn't offer support for Windows 7 for my system. Do I really need to downgrade back to Vista to get my mic back?
I've seen there are many others who have the same problem - and i've tried several of the fixes, checked device manager and made sure settings are correct. This worked beautifully before the upgrade now, pc is faster, but mic is out of order.
any assistance for what seems to be a common problem after upgrade would be appreciated.

No Sound device recognized

I have a e9290f Pavilion. I just re-installed the system with HP recovery disks. I have no sound and the device manager does not see a sound device. It has onboard sound. I downloaded the new driver from the HP site and installed, re-booted and it still does not see the device. My thoughts is the onboard sound on the motherboard is "messed up". I bought this computer in 09 and it hasn't been used much. It is running Win 7. I went to the bios and changed the setting from Auto to Enabled and rebooted, that didn't work. I went back to Auto and rebooted, that didn't work. I'm afraid I need a new motherboard or have to buy a sound card. Any thoughts would be welcome.

Hi
Thanks for your reply. I did several steps and made a determination it was the Realtek sound chip on the motherboard. As in my previous post I did a clean install, that should have put the original drivers to be loaded, didn't work. Then I downloaded the updated drivers, didn't work. Then I went to the Reaktek site and downloaded their drivers for the chipset on my motherboard, that didn't work. Then I did a google search and found that this motherboard has had several problems and indeed HP last year was replacing them. Because this computer at that time was being used by my son, I didn't know of the sound problems. He went to work in Florida about 6 months ago and the computer was sitting in the closet until about 1 month ago when I took it down considering to put Win 8 on it, and discovered the items I have been posting here. The solution was/is not to replace the motherboard ( I hope nothing else goes wrong with it because from what I read on the google search, sound going out is/was not the only problem ) but to install a sound card. So I went to Best Buy and bought a Creative sound card and installed it, drivers etc. and now everything is working fine. Thank you for trying to help. I checked out your link and that help page does absolutely nothing for you if you have no sound device showing up in device manager. That clearly means device manager is not seeing a sound device, all the drivers in the world and all the troubleshooting is not going to change that. Thank you for trying to help.

My sound device has been removed

HP pavilion G series, Windows xp.. failure to find sound device.. removed some programs that were not being used

hi Pinball_Wizard,
Welcome to the Forums.
CD/DVD issues are commonly fixed by running the microsoft hotfix from this article:
http://support.microsoft.com/kb/982116
If the problem is not solved, the issue is most likely hardware related. Either the ODD is faulty or the connection from the ODD from the motherboard is failing. If you don't have an external USB ODD enclosure (like this one) to test the ODD, then you may need to bite the bullet and just replace the ODD directly.

Suddenly no sound coming from HP Pavilion 500-339 Desktop

I've had this computer less than a month without any issues. From a couple days ago there is no sound coming from any source (various speakers, headphone jack directly into computer).
I have checked everything, i.e., checked all the external cables, used the Windows diagnostics and checked all sound devices, volume settings, checked for mute etc. No issues have been detected with the audio hardware and drivers.
I've also done a system restore, removed recent Windows updates (within the week), uninstalled and reinstalled the IDT high-def audio drivers and still nothing. Every time I do a diagnostic it says the audio is working properly yet no sound comes out for anything.
Any help would be appreciated.

USB 3.0 Upgrade for HP Pavilion dv9700 CTO Entertainment Notebook PC

Is it possible to upgrade my HP Pavilion dv9700 CTO Entertainment Notebook PC to USB 3.0? I've been searching the website and google and haven't found any concrete answers just yet. I'd rather not have to buy a new laptop just to get USB 3.0. It's been the most reliable pc I've ever had and I don't wantn to replace it!
Thanks,
Paul

Hi,
You have to buy a new laptop or swap the system/motherboard or buy an Express card - USB 3 (I've got one) or PC card - USB 3. For desktop , this is much simpler, a PCI - USB 3 card will do.
