HDMI In Problem

When I use HDMI In to record IPTV input, the sound is broken. You cannot listen it. Does anyone have the same problem?

I had one method can normal record . (1080P, TS format,10M bitrate, 96000,2 channel)
1. first time, you need record over 10 seconds if audio had noise. After 10 seconds to stop record. Second time record audio will be normal.
You can try to do.

 

Thanks. It works.
