I have XP on the machine also, and from XP, using the NVidia driver for XP, I can get both video and sound on the TV. ONLY on the TV--no sound comes out the local speakers when the HDMI is connected in XP. (Video works locally at the same time in Linux.) I have never been able to get sound on the TV from Linux. In previous attempts, with different mixers, I could either (1) not see the volume sliders, or (2) see the sliders, but they were set immovably to zero.
b) I mean within microseconds. I need the sound synced to the video, because I want to watch musical performances from YouTube, or tv programs, or videos from DVDs, or whatever I can see and hear on the local desktop. c) I think I answered this in the previous question (b), but if I misunderstand, please clarify the question. (I'm not trying to look at and listen to one signal on the desktop and something different on the TV at the same time, even tho Linux is a multitasking os.)
