I was not abel to get sound to my Sony Bravia through HDMI. I went to update the Realtek drivers, did so. HDMI started to work, but now no Realtek manager! I also use the line-in from my stereo to record/converst LPs to MP3s. Now, the line-in does not work. The computer seems to recognize it (if I go to recording devices, the line in is there and showing audio levels) but no audio comes through. I am at a loss. Any suggestions would be greatly appreciated, Victor Dell/Studio 540 Vista SP2 32 bit Intel Duo Core E7400
