I cannot seem to get a straight answer on this... My initial assumption is no, but that is based on the assumption that the speed of sound is constant, and only changing the medium's density or temperature could change it.

This is a motionless situation, I.E. I am sure it is not affected by the doppler affect. It is simply sound diffracting around a hole, however the sound is at a constant frequency

No it does not change. But to the observer, it appears to change. I think it is called the Doppler effect.

The speed of sound changes based on the medium of transmission. Placing openings in the way has no effect on the speed of the sound that gets through.
On the other hand, if you have TWO openings with a gap in between and that gap is just the right size, you can get some odd sound effects due to constructive and destructive interference of the suddenly isolated wave forms trying to rejoin - but it is a little harder because the openings cause the sound to re-radiate as though the openings were the sources. This won't happen with only one opening. It also won't happen if the gap is the wrong size.

In an ideal gas approximation, no.
