Pavilion dv7 internal speark stopped working

The internal speakers on my notebook stopped working.
I followed the instructions in another thread here which involved uninstalling the IDT device ands its drivers and downloading and installing sp48830.exe.
However, when I tried reinstalling from the download. I get the error "The hardware detected is not supported by this IDT software package. The install will be aborted".

Pavilion dv7 fingerprint reader stops working after several hibernate/suspend cycles

After severl hibernate cycles, the fingerprint reader on my Pavilion dv7 latop stops working. The indicator LED no longer flashes (in either colour), and nothing happens when I scan my fingerprint. I'm forced to revert to password login.
This has been an issue since getting the laptop. Fingerprint scanning works fine at first after a reboot, but when I hibernate (or, for that matter, suspend) the laptop after using, I'm never sure whether the scanner is going to work when I restart it. Sometimes it does, sometimes it doesn't, and the only way that I've so far found to fix it is to reboot.
I've tried using installing the latest driver from HP's support site, although it seems to be dated May, 2011, and, interestingly, claims to fix a problem with not restarting after several hibernate cycles (hint: it doesn't). I've tried uninstalling and then re-installing the driver. Doesn't seem to make much difference.
Laptop is an HP Pavilion dv7-6166nr with Windows 7 64-bit Professional installed (although the problem was present with the factory-installed Windows 7 Home Premium).

Try downloading and running the HP Support Assistant if you have not already. It can search for updates for you specific to your notebook. Here is a link to the download: http://goo.gl/gvpTr

Internal microphone stopped working today - Pavilion G7 - C2M31UA#ABA / Windows 8

Hey there
I am using Skype quite often, but today my internal microphone stopped working. I restarted Skype, my laptop and I also followed all steps of you trouble shooting page. No change ...
Any ideas?
Thanks
Bettina
This question was solved.
View Solution.

Enter your device manager.
Can be found by pressing windowskey + x.
Press Sound, video and game controllers.
And right click and remove the one called Realtek high definition (should be something like that).
Reboot the computer, this should make it reinstalll the driver på itself.
If this doesn't work, search for the program called recovery manager. In here you pick the one furthest to the left, called something with reinstall driver. Here you find the one called IDT High-Definition (HD) Audio Driver check it, and press install.
Since it used to work, and you dont have windows 8.1. If this still doesn't fix it, it must be some setting regarding your microphone. So try right clicking your speaker icon down in the right corner, when in desktop mode and pick recording units (translating directly from danish). Please let me know what you see in here.
Best regards
ThaCrash
Troubleshooting Steps:
1. Reinstall Adobe Reader.
2. Turn it off and on.
3. Press Kudos star.

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3. When I purchased the monitor a few weeks ago it worked perfectly when computer was in clamshell mode or with lid open. Now external display has stopped working. When I turn on display it scans for signal but does not find it and then immediately goes into sleep mode. I am using a DVI connection with the adapter for the mini display plug. REALLY FRUSTRATING. Any help would be extremely appreciated.

Hi lancekatigbak,
If you're having issues with the display out on your MacBook Pro, you may want to take a look at the troubleshooting steps in the following article:

Hello schneids,
I see that you are having start up problems with your HP computer. I have a couple of suggestions that may help with your issues.
Here is a link to some troubleshooting steps that may help resolve your issues.
If you are still having trouble I would suggest testing the power adapter or trying a different power adapter. Most retailers will let you try a power adapter on the computer to see if it works.

HP Pavilion dv7-3165dx has stopped recognizing the DVD-Blu/CDROM

Help,
My HP Pavilion dv7-3165dx has stopped recognizing the DVD-Blu/CDROM player issues.
Literally in last 24 hours. all was working fine. then Stopped.
Device not working is : hp DVDWBD TS-LB23L ATA Device
Whirrrs like reading disc...even gets the disc icon on windows.
Have scoured these boards and tried everal of the solutions.....
1. tried uninstalling and reinstalling Driver as described on these boards... didnt work
2. tried MATS on microsoft website....didnt work
http://support.microsoft.com/mats/cd_dvd_drive_problems/
3. Tried the Revo uninstaller attempt .... didnt work
4. tried the CC Cleaner attempt ... didnt work
5. Tried the ATA channel delete ... didnt work
6. tried the BIOS update here : HP Mediasmart DVD failure - HP Support Forum
as additional clarification..... no physical damage to computer....Discs being used are all functional Blu or CD or DVD.
HP Mediasmart DVD is still not working.
NO installation of new programs prior to this going on.
My same fire wall program, anti-,malware has been on this computer since I purchased it 7 months ago.
No software changes in system.
I do not use the Comodo firewall system either.
Thank you

Have you tried installing a trial Blu-ray player. Don't use one from Cyberlink as it's too close to Media Smart DVD.
Use Arc Soft
http://www.arcsoft.com/estore/software_title.asp?ProductCode=TMT5P&gclid=COXEpJ6CqqcCFQEKbAodpQdSCw
----Will give that a whirl when I return home.
Have you tried the obvious and picked a Windows restore point to where it was working ? -------Windows 7, in that particular machine isn't letting me dial back for an earlier restore point..... it isn't even letting me see dates....Believe me I would have been happy to dial back a week or two. Not sure why, Havent been able to dig in that direction....was trying to be careful about not digging a deeper hole before moving all important work files and stuff to a different machine before toying with windows deeper.
Maybe the drive itself has failed, do you you have another HP laptop that you can try it in ?-----have several HPs...might try that soon.
Check "Autoplay" in the control panel.----have done the autoplay fixes that have been proposed in other chains of similar problems....no avail.
I will keep throwing ideas at you no matter how simplistic they may seem. I find that it starts people thinking in another direction.     --------Believe me, I appreciate it, just as long as it doesn't devolve into .....Is the machine plugged in?
Have you tried burning a DVD with it ?   Not yet, that is a good idea.
Try installing Image Burn and see if the drive will create ISO files with a Blu-ray disk. You will get a warning that Image Burn can't do this, but continue and let it dead the whole disc. Let me know if that works and I will give you the software to play the movie from the ISO files.
http://www.imgburn.com/index.php?act=download
Use mirror 8 provided by Image Burn.
What version of Media Smart DVD are you running ? Was using the most recent release......then uninstalled it and went back a few versions... to one that was linked to in another similar thread.
Thanks.

My internal microphone stopped working on my imac?

My internal microphone stopped working on my imac? I only noticed when I tried to use Skype. It was fine till a recent change to hard drive after a mechanical failure and a clean reinstall. I have USB headset and it works fine, in and out. Any answers/suggestions would be much appreciated.

Check your settings in System Preferences>Audio and make sure that internal microphone is selected on the input tab.

Internal mic stopped working today, please help! C660 1F1

Hey guys,
My laptop is a Satellite C660 1F1, and it runs Windows 7, 64bit version.
This afternoon, my internal mic stopped working. It was just fine this morning. Yet I can still hear people on Skype perfectly.
I've checked all my settings, and according to them, everything is just fine. But it isn't. The little green bar that shows received sound doesn't move at all. It only moves a tiny bit when I tap the mic with my finger.
I've reinstalled drivers, I have my settings adjusted for maximum mic usage, but it's just not working.
I don't know what else to do, and this mic is the only way I can contact my family right now. Someone, please help me!

Pavilion G7 wireless adapter stopped working and now will no longer boot.

I bought a Pavilion G7 about 7 months ago.
After a couple of months, the wireless adapter stopped working, it just disappeared from the Device Manager (Win7 Home).
I reset the computer to factory settings and it fixed that problem.
One month after this, the wireless adapter problem returned, I tried to use system recovery to restore it to a previous point, no luck.
I closed the laptop after this, didn't turn it off.
Opened it up and decided to watch a video I had on there, I had to pause the video halfway through (used Windows media player). Came back to continue watching and the screen was black. No lightbar activity, just blackness.
I pressed a few buttons, nothing.
Decided to do a hard reset (hold the power button for 8 seconds) then I left it and turned it on again, the blank screen returned, no signs of life, no boot, no HDD activity, nothing. The caps lock button was on, the wireless light (of course) was orange.
What on Earth has gone wrong? What can I do to fix this?
Thanks.

X201 Internal Speakers Stop Working

I am having a problem with the internal speakers on the X201. Basically, the speakers just stop working. I could be in the middle of playing a song and the speakers pop and then go out. I have to reboot the system for them to work again. Headphones still work despite the fact they go out.
I am thinking this is a fault with the IO Assembly board, but am not sure.. I have reinstalled Win7 clean with updated drivers and still see the same problem.
Another interesting thing is I keep getting the disconnect/connect sound ( like you are plugging in a usb device ) at random times. That always seems to correlate to the windows AUDIODG process.
Any ideas?

As you have already reinstalled the Operating System and drivers are also updated.
I suggest you to update the BIOS and check
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/6quj16us.exe
If then also the issue persist and your laptop is in warranty then you can contact the support center.

Reset the PRAM > Resetting your Mac's PRAM and NVRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Note: if you are using a wireless keyboard and the Hardware Test and/or Pram reset is not working, then you may need to use a USB keyboard.

Internal sound stopped working

My internal sound suddenly stopped working. I can still hear sound with headphones, but the internal speakers are not functioning. The trademark start-up sound (Beatles Day in the Life rip off) is the only sound that comes out of the MacBook. Within Systmem Preferences, Sound, the output tab reads "The Selected Device Has No Output Controls." And within Utilities, Audio MIDI Setup, Audio Devises, the Built In Input Devise is active, but the box reads that "Output Is Not Suportted." Also when I try to adjust the volume with my F10, F11 and F12 keys, the Speaker Icon is in grey, all the audio bars are in whilte and there is the small circle with line throuh it below, that would indicate mute or no sound. Looking for direction to resolve the problem. Thanks.

This also worked for me. Red light on, put in jack, wiggle, pull out jack, red light gone, volume controls and sound work again. Thanks.

Hp Envy Dv7 fingerprint reader stopped working ! what should I do?

Fingerprint reader of Hp Envy Dv7 stopped working after I downloaded and installed an update as Hp support assistant showed a message

I understand the fingerprint reader quick working after an HP Support Assistant update.
What was the name of the update that was applied?
What is the product number?
NOTE: Do NOT provide the serial number.
If you perform a system restore to a date before the update, does the fingerprint reader work?

Pavilion dv7 fingerprint reader not working

Hi.
My HP Pavilion dv7 fingerprint reader isn't working. I have the SimplePass software that's powered by AuthenTec. When I open the SimplePass software, it doesn't seem like it knows I have a fingerprint reader.
I've tried installing new drivers but I can't seem to get anything to work.
Any help is really appreciated.

lyscarn,
Could be the order in which you are doing things, could be the HP SimplePass version would be happier on a different version, could be that you just need to kick the system (metaphorically speaking).
Assuming you are running Windows 7 or Windows 8 AND that you are not running Digital Persona
then
the following may help.
Find, open, and follow the instructions in the file named: Simple Instructions to Upgrade HP SimplePass
Kind Regards,

Internal Microphone Stopped Working

My internal microphone has stopped working. I use Garageband frequently and one day, suddenly, it just stopped working. Even in the system preferences there are no bars to indicate any sound being monitored. This is very strange as I haven't dropped the computer or done anything that might cause a hardware malfunction. I would really appreciate any help because I'm a musician and this was my way to record ideas on the fly.
I posted this question a week or two ago to no avail: https://discussions.apple.com/message/20038384#20038384
Thanks!

I want to add that people can hear me tapping and buttons pushed when using skype.
