I have a pioneer 1019 receiver and have configured the DVR input to use HDMI input 3 and optical-1 for audio. I connect my laptop using an optical audio cable and dvi-to-hdmi. The video outputs fine to my TV, but the audio only works when the dvi is not connected. With the dvi disconnected, the audio works fine. It is not clear to me what about having the dvi connnected makes the audio not work. And, I do have KURO-link turned off (since I have seen this suggestion on other similar posts). Any ideas?
