Can not activate the sound
I have a HP Pavilion dv7 1232nr. Everything has been working great until two days when I realized that the mute button at the top of the laptop is RED (silent) and I can't seem to "reactivate" it or change the volume using the key above the keyboard.
When I go into Control Panel, Manager of devices, it is said that everything works correctly. My headphones will work, but other that that, I can not all sound from the internal speakers. I see green bars move when I music, etc, but I am unable to hear it without a helmet.
I spoke with a colleague and she said her daughter has had the same problem and they had to download something, but she can not remember what it was.
Anyone able to help? Thank you in advance.
The sp41479 is this driver. :-)

I can not all the sounds from my computer
I can not all the sounds from my computer. I hae tried to click place volume icon in the taskbar, but it won't let me and she also come with 'there is no active mixer device. To install mixer devices, go to control panel, click Printers and other hardware, and then click hardware, but it's not it will fade. Please can someone help me.
The sndvol32.exe file is possibly corrupt.
To replace, there are two methods:
(1) open the Windows Explorer > tools > Options > view > make sure that show hidden files and folders is NOT checked. Access the c:\windows\system32\dllcache and locate sndvol32.exe > copy it into the following folder c:\windows\system32, overwrite the existing file. > Re-boot, you should now have access to your sound mixer and be able to place the icon on the taskbar. If for any reason any you do not find the dllcache folder:
(2) put your XP CD in a driver, don't let it start. Then: Start > run > type in msconfig > enter or OK > extract a file > 1st enter in sndvol32.exe > in the second point of the box to your CD player > 3rd enter in c:\windows\system32 > extract file > run over if necessary, close everything and restart.
If the above does not work, re - install you 'audio drivers, although I would only do it as a last ditch measure.

IDT installed, can not hear the sound being transmitted
I tried to fix the audio for a few days now, I got the IDT High Definition CODEC after awhile, but I can't hear the sound being released now.
It would be great if someone, perhaps a professional give me sent assistance because looking around on the internet has proven that anyone had a similar problem that has not been resolved by a simple reinstallation of the driver, thank you.

May be stupid, but a solution to my problem. A full stop after you have reinstalled the driver seemed to fix my problem (after the installation of the driver is restarted too) thanks HP Forums for all the help on the recovery of my audio well.

I moved my computer and added a user to the system. It will now not all sounds and troubleshooting it the system state is disabled and a code 32. How to activate the sound?
Hi MelWideman,
Method 1
I suggest you run the troubleshooter of playback of the sounds and check if it helps.
No sound in Windows
http://Windows.Microsoft.com/en-us/Windows/help/no-sound-in-Windows
Method 2
If the previous step fails, then I suggest that you manually download and install the updated drivers for the card its installed on the computer by visiting the sound card manufacturer or computer manufacturer's website and check if it helps.
