Absolute darkness only. Light wakes me up. For example, too less light coming in from the blinds because its a rainy day keeps me sleeping longer. Over the years, I removed my digital alarm with bright red numbers for this reason too. It got to be a bit too bright. =\
As for sounds .. it seems to only wake me around about 30 minutes to one hour left of my 6 hour sleep. Why six hours? Because my bio alarm wakes me up always at 6 hours on the dot. I can keep sleeping after that but it'll usually be light sleep. I'd also wake up every 30 minutes to 1 hour if I keep trying.
