I have been using onkyo nr515 with my first setup gtx 670 sli to bitstream audio. after i installed graphics drivers and stuffs and plug in the hdmi between the receiver and gtx 670 i get that "hdmi" light show up on the receiver display. i get sound from browser, playing all kind of computer games, i.e. starcraft 2 and the witcher 2, i get sounds for these games. then i switched to radeon 7990 single card, this card got an hdmi output, i still connect the hdmi cable between the receiver and 7990. btw i have been plugging in the hdmi cable using the "BD/DVD" hdmi slot on back of the receiver. with the 7990 the "hdmi" on the 515 display is blinking, and it dissappear when i am not using audio, if i remember correctly it used to stay on permenantly. When i play starcraft 2 and the witcher 2 i get no sounds and the "hdmi" doesnt illuminate on the 515 display.
what is it doing that? i want to be able to hear sounds from running all application. i didnt change the setting in the sound control, i still let apps get exclusive control.
any ideas ?
