Its still all over the place. With some mods i can use my current stands and i will think of screwing the front speakers to the wall. The center speaker is now behind my monitor. Other two directly next to them. So for real surround experience i have to change all positions. But for now its good enough. Have plenty of studying to do
Have you tried another PC? You should at least get some picture.
Saves at least a few euro's. Also i bought the cheapest toslink cable: works fine
