Hi,
I have just bought an ATI Radeon HD5770 (MSI R5770 PMD1G) graphics card, which I connected to my Onkyo TX-SR508 receiver, which passes through the video signal to my LG TV. Part of the reasons for me to upgrade were its uncompressed HDMI surround audio output features.
Unfortunatly I’m having this issue now, that whenever I turn my TV off, the receiver also stops playing sound. The screen flickers for a bit, disappears from the list of displays, and in the sound configuration it lists “ATI HDMI Output - Not plugged in”. This effectively means that whenever I want to hear sound from my PC, I need to keep the TV on. Boo!
Previously I had an Nvidia 9600GT also connected through HDMI (it used internal S/PDIF passthrough for audio); for that the screen also flickered when I turned the TV off, and the sound got briefly interrupted, but kept playing after that.
Does anyone have a clue what may be going on? I’m using Catalyst driver version 10.8 on Windows 7 (64-bit).
My personal suspicion is that by turning off the video output the audio output also gets automatically turned off... Would there be some way to make the card still send the signal to the receiver? Maybe some way to prevent it from detecting that the TV turned off?
