I mainly hunt by myself. I feel your pain with what you are talking about. One thing I love about hunting by myself is I can be totally quiet. When I approach a piece of cover no matter how big or small, I am completely quiet. I can still hear my dad whispering to me "don't slam the car door." I don't use a bell or a whistle, and my dog is an old veteran, so he knows the game, and I don't have to say or yell anything to him.
As far as rooster getting up, and you don't have a shot, I don't know, that's just the way it goes. If you can put yourself in range, that's really all you can do. I always try to hunt into the wind for 2 reasons, obviously the dog scents better, and the birds can't hear you as well.
Another tactic I've used many times is I'll park my car on the downwind side of a piece of cover, and walk to the other side obviously a couple hundreds yards away from the cover, and hunt upwind. I've found the car will make them hold at the end similar to a blocker. Sometimes I leave the radio playing with the windows rolled down just to make birds think someone is talking.
Hope this helps. I don't claim to be any kind of expert. Good luck this fall.
