saumansch,I don't have a good solution for you.Some snow conditions are impossible to move quietly in.Here,when it gets very cold,say 20 degrees F or much colder,the snow will be like a very dry powder and if there is no thawing,it can be very silent for stalking.If you have had freezing and thawing or if the temperatures are just at the freezing mark,you may have to use some sitting tactics for awhile,if that is possible.
Also,where I am the conditions constantly change so it often is just a matter of waitng a few days and things can get better.
I suspect that where you are,the snow conditions may stay for long periods of time?
