This is a bug I've run across on HP Probook 6XXX, 6XX, 8XX and HP Elitebook 8XXX, 9XXX, 8XX, and 1XXX laptops. This is mostly an annoyance and usually the volume works, the mute button works, but the orange "mute" indicator light is stuck on orange.
If you look through HP forums, you will see HP Support claim this is a BIOS issue. I've run across this issue several dozen times and each time I do a fresh installation of Windows on the machine.
The problem is usually caused when Windows Update installs the Audio Driver during the OS Install Process. Windows Update will install a generic driver that works fine for the audio, but does nothing to control the mute indicator light.
The solution is to download the actual HP driver from the HP Diver Support site. If you are installing Windows 10 on the machine, you will need to download the Windows 8 or Windows 7 driver. While the installation process claims you will need to the reboot the computer after the driver install but this is not always necessary.
In Windows 10, you can use the Windows 8 driver. Upon completion of the install, the light changes white immediately.
HP Elitebook 8470P
Windows 8/10 64bit: Use IDT High Definition (HD) Audio Driver SP63916.exe
Windows 7 64bit: Use IDT High Definition (HD) Audio Driver SP60317.exe
For some models, there are no Windows 8 or 10 drivers available. You can use the Windows 7 drivers instead.
Many thanks for sharing. Can't believe I didn't think of this solution myself. I have an HP Probook 6460b and whilst HP would have you believe it doesn't support Windows 10, this is the only thing that doesn't work. I deleted the generic Windows Audio devices and installed the Windows 8.1 64bit drivers as you suggested and now it is 100%. With a SSD in place of the optical drive, it serves me well in a holiday home. Thanks again.
ReplyDeleteThanks so much for your solution. I did a recent Win 10 install on a HP Probook 6470b and noticed the button staying orange. Other solutions I looked up weren't as clear as yours, so I simply went to HPs driver page and downloaded the IDT Audio Driver and it immediately fixed the button. Really appreciate you sharing this info!!
ReplyDeletestill its not working after updating the drivers, i noticed that the orange mute light is getting on along with Laptop Power On, and its not going off, but my audio is working fine with Bluetooth headphones, its only the audio in laptop speaker and the plug out headphone is got muted
