I am having a problem with my audio device. I have an HP m7650n desktop and when I go to
Start > Control Panel > Sound, Speech, and Audio Devices > Adjust the System Volume
it is all grayed out and I can't change anything. Second, if I click on Advanced Volume Controls, it says:
"There is a problem with your sound hardware. To install mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware."
What is the problem here? I re-installed the driver for the Realtek HD Audio Manager, and it still doesn't work.
Also, sometimes hardware detection pops up and says it's trying to install an unknown hardware, and I think it's trying to install the audio chipset.
Under Device Manager, under the section "Other devices" there is an Unknown Device with an exclamation point on the icon. What should I do with this, and is this a part of the problem?
Thanks in advance.
