I don't see how that's related to the exhalation pressure relief. EPR is a comfort feature and if you don't need it there's no reason to have it.
A chin strap is used to help prevent mouth-leaking.
The whining sound could be a result of the elevated breathing rate we have when we first put on the mask. After we calm down our respiration rate falls and the whining goes away.
Both of these issues tend to subside as our bodies and minds adapt to CPAP therapy.
There are several advantages to the ResMed S9 autoset so I would try to keep it if you can. Some white noise in the background helps muffle the sound of the CPAP machine.
