I am currently running the system with the nVidia GeForce 9600 GT which i have to the Samsung with the help of the DVI to HDMI connector. as my TV is not having any support for the SPDIF which help to send the audio via HDMI so i have bought a jack which is having the stereo RCA cable. TV did not allow the choose the audio input and automatically select the analog stereo input and i am unable to play sound on the same. So let me know about [177.82] DVI -> HDMI + analog audio, but no sound. Thank you.
