I have a Yamaha Home Theater System that I connect to my Windows 7 PC (via HDMI) for playing audio. My TV is broken and I can only use my monitor to display video. This monitor does not have HDMI and only has VGA. Is it possible to have both VGA and HDMI plugged into my PC with HDMI porting audio through to the home theater system and VGA porting video through the monitor simultaneously? (I have already tried running an auxiliary cable from my PC to the theater system, but it doesn't get the same sound quality as the HDMI would).
