Integrated sound card for main board

I just bought an Asus p5ld2, which can be used in performance.
The sound of the integrated sound card on the motherboard can be played well.
When I chatted with lp qq today, I found that I could not record the recordings, so I was so depressed. Why can't I play a recording? Both the front-end audio plug-in and the rear-end plug-in have been tried. audio and video can be played at the same time, that is, audio cannot be recorded, and audio cannot be detected through hardware testing.

Others say that the motherboard is faulty. I am in trouble asking for Js. It is estimated that it is a plug-in problem. It is good to open the chassis.
No jumper, plug online, start up, use the system recording test, the effect is quite satisfactory.
