Hi,
My HTPC (Windows 7 - 64Bit - Home Premium) connected via HDMI to an AV-Receiver Onkyo TX-NR818 will resume from standby / hybernate if I switch on the AV-Receiver.
This didn't happen with a nvidia graphic card on the old system.
I disabled the following hdmi options in the AV-receiver settings already:
hdmi control (RIHD) - also known as HDMI CEC
ARC (Audio Return Channel)
Pass Through
On the other hand: If the receiver is connected to the PC via HDMI the PC will never go to standby or hybernate. Disconnecting the receiver from HDMI will allow the PC to go to sleep state after time set in the Windows options.
By the way: Onkyo is stating that it's not an issue of the receiver. But I believe that not at all, because the data exchange on the HDMI connection must cause this issue.
1. Is there any option in the driver or ... to disable this functionality?
2. Is a tool available to log the HDMI data transfer in the driver?
Thanks for any ideas or solutions in advance
