hopefully you can help.
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?
