if i listen to the ambient sounds i think i can hear both ambient sounds playing

I am one of those rare users who uses both, the more ambient sounds the better (and it works great)

They will both run supplying sounds.

Okay, so I can just turn off the ambient sounds from dynamic surroundings ?

Depends on what you want. If you want ambient sounds, but do not want the ambient sounds of DS, then why install DS? The players I know of that use both want both.

Closing as answered. If you have further questions just ask.
