Hi community,
hopefully you can help.

Short description:
My Yamaha RX-V771 is not detected at my dual-display setup´if i turn off the connected TV, so sound output over HDMI is no longer possible (crossed speaker icon in the notification area)!

Current Intel graphics driver
DVI: Asus P8H67-M EVO -> Intel Core i3-2120 (HD Graphics 2000) -> Samsung Syncmaster 226BW
HDMI: Asus P8H67-M EVO -> Intel Core i3-2120 (HD Graphics 2000) -> Yamaha RX-V771 -> Samsung LE40C650!

1. If i turn off the TV, the HDMI sound is disabled too (Yamaha receiver is not recognized)!
2. Monitor 1 (Samsung 226BW) also shows only a black screen! If i send PC to sleep, after wakeup the resolution is set to 1680x1050 native, but the sound stays disabled!

After turning off the TV, i like to listen to music over HDMI and the Yamaha RX-V771!

I hope, you can help?

Best regards

1. Make sure the correct HDMI device is the default audio device. Many receivers are seen as different types of devices depending on whether TV is on or off.

2. Make sure the computer's graphics output is set to a valid home-entertainment HD video resolution. e.g. 1920x1080 or 1280x720. Common computer resolutions, like 1600x1200 or 1366x768, usually do not work in one way or another.

3. Try the "AVR Audio Guard" utility. See http://www.avsforum.com/t/1317491/silent-stream-bug
