HDMI Video and Audio Problem

Hi all!

I just finished putting together my HTPC (see below for specs if needed) and I'm having a problem with my HDMI audio connection to my 40" Samsung 720p flatscreen t.v. I do NOT have cable television and only get the digital over the air stations. I have my HTPC hooked up to the t.v. under HDMI1 and our Xbox 360 under HDMI2. What happens is while I'm on my PC playing a game or watching Netflix or whatever and I switch over to basic digital t.v. to check something and switch back to the PC, I lose audio. The only thing I can do to fix it is restart the PC or unplug the HDMI cable from the t.v. and plug it back in. Is there a work around that doesn't involve a boat load of money or is there a setting I'm not aware of? Here is what I got:

OS: Windows 7 Ultimate 64-bit
Motherboard: MSI FM2-A75MA-E35
CPU: AMD A10-5800K Trinity 3.8GHz
RAM: G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866
HDD: Western Digital WD Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s
BRDVD: ASUS Black 12X BD-R 2X BD-RE 16X DVD+R 12X DVD-RAM 8X BD-ROM 8MB Cache SATA Blu-ray Burner BW-12B1ST/BLK/G/AS

Please help!!!

  1. Try nircmd.exe (google it). I placed a shortcut on the desktop:

    "C:\Program Files (x86)\Nircmd\nircmd.exe" monitor off

    It resets the HDMI out, and you are back to business.

    The program does a lot more - great documentation at http://www.nirsoft.net/utils/nircmd.html
