IDT High Definition Audio CODEC unavailable

[HP_Pavilion1404]

I can’t use Skype for the below reason.

In the control panel, sound shows the below

(In Japanese, Micropone “Currently unavailable”)

（IDT High Definition Audio CODEC)

 

I could not select the mic as setting device, it is impossible to choose.

(Unable to select the gray out)

In some comments on the web shows that only one device can be recognized as “recording”, I changed the other device unavailable, but could not select the mic as the available device.

Even though property of microphone shows the connection of 3.5 mm jack in rear, panel, the connection of mic does not affect the status of “currently unavailable”.

I changed several jack on the PC panel, no status change happens.

Mic works when it connects to other devices.

Wiondows 8.1、

PC is HP Pavilion Slimline 400 PC

Opened the device manager as follows, but could not find any unknown devices marked out with a yellow question mark.

Thank you for your sugestion.

Driver has been installed and upgraded shown as below.

Unfortunately, the mic status "currently unavailable" in the Sound has not changed.

The information listed above in Japanese, is difficult for me to understand.

Let me try to translate to English

" The process to add the service "STHDA"  for device instance ID HDAUDIO\FUNC_01&VEN_111D&DEV_76F3&SUBSYS_103C2AF7&REV_1002\4&2DCAAFFF&0&0001 has been finished  at status 0。 

In addition to that, event detail information is as follows.

Thanks to the advice, I tried several times.

In addition to the drive shown in the advice, I tried to update the other audio devices from HP homepage but could not updated.

By the way, the status of the recording devices "currently unavailable" does not change  regardless of whether the microphone's status in or out.  To put it another way, when the microphne is not connected the plug, the status is still "currently unavailable", not "does not connected".

If this information helps to the solution, it would be great pleasure.

Thank you for your cooperation.
