Hello All, I was going to use HDMI to transfer sound as well as video to my SONY LCD TV. The problem is that I don't really know how to do it. My video adapter (ASUS EN8600GT/HTDI) has an SPDIF-in connector to pass the audio stream through HDMI interface. I connected my motherboard's SPDIF-out to this one. Then I un-muted 'IEC958' as described here: http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIF But all my attempts to play any audio file gave me no sound. Is there anything else I need to do? My TV accepts "Two channel linear PCM; 32, 44.1 and 48 kHz; 16, 20 and 24 bits" audio over HDMI input. When I'm trying to play back a file via mplayer it says the audio stream is 2-channel, 48000Hz PCM. So it should be fine... But I still get no sound. What else could be wrong? My motherboard has one internal and one external S/PDIF output. I don't think there is a difference between them, but the internal one is connected to the video card. I read the manual but it said nothing about configuration of the S/PDIF in terms of which one to use. So I assume both outputs should work at the same time... But I might be wrong here. I would appreciate any help! -- Best regards, Andrew
