Hey guys. I use the normal pc - monitor output with the usual 15 pin cable, using windows 7. My PC supports that and HDMI, so Ive always had my monitor running and HDMI to my TV. When I have had this connected - I always used my sound system for sound as the hdmi cable never picked up sound from the TV. All of a sudden my tv doesnt worked with cable to the monitor and doesnt transfer the sound to my sound system (green speaker port) and ive no idea what to do. My tower works with the HDMI cable though........and sound comes from the TV which has never worked before.
