Windows 7: Audio missing shortly when moving playing video to another screen

16 Jun 2013   #1

Windows 7 Ultimate x64
Audio missing shortly when moving playing video to another screen

I've setup dual screen for my PC.
One is Samsung UA22D5000NM (my primary desktop, run in 1920x1080, driven by DVI port, using DVI-to-HDMI converter to my Samsung),
and LG 22LG30R-TA (my extended desktop, run in 1680x1050, driven by HDMI port, direct cable from HDMI port to HDMI input on my LG).

And yes, I've disabled the auto detect feature of HDMI to my LG using a small duct tape.

The problem is,
while I play video (a movie) using potplayer on my main desktop (samsung) using desktop speaker (I'm on Win7x64 SP1) and drag this potplayer (while playing video) to another screen (my LG), the audio missing (goes silent) for a second or two and automatically rise again. After the video moved to another screen, the audio gets playback still on my desktop.

What is this missing audio ? Is it always like this when moving actively playing audio to another screen ?

Are there any solution for fixing this ?

And also, is there a way to automatically switch the audio output to HDMI (to my LG) after I move the video to the extended desktop (LG) ?

Thanks in advance.

For better understanding, this is my setup :
Core Unit :
Core i5 3550 run at normal clock speed (without OC),
Gigabyte GA-B75M-D3V rev 1.1,
Sapphire ATI HD 5770 Vapor-X 1 GB DDR5 128bit,
Xigmatek NRP-650 WV,
Storage :
1 x OCZ Vertex 4 SSD 128 GB SATA3,
