As it happens it seems SPO isn't available anymore anyway, at least not on Nexus. The problem for me with any sound mod is I have to use headphones and need to use 1/2 volume for all sliders so all sounds can be exaggerated a bit. The main thing I have issues with in SPO is that horrendous reverb in buildings even if he has reduced it.Well the reverb was even more present in the first version, i believe the author mentioned that he tried to fix it but is at the moment limited by the CK. So he lowered the reverb a bit for the moment. I realize mods like this are not for every one ( Well actually, every mod can be seen that way. ) but after having used SPO for so long i did not think i would find a mod that does what ASO does, so i was quit surprised how it all sounds in game.
The mod does "sound" good

If anything needs an overhaul now it's the game sounds. Most everything else has been done where possible and considering the limits of the engine and CK I'm surprised at what modders have achieved. I'd love to go forward in time to see what TES 6 has in store for us as far as modding opportunities, if any...could be interesting.
On another note I found this house mod while watching a review video of another mod...

Dream of Moon

I like the look of this one also since I'm trying for a Steampunk character theme this time, it possible. Used to be at Nexus but was removed so now it's at TES Alliance and you have to be a member to download.
The Moors

To go with that theme is this magic mod...
Dwemerverse - Dwemer MagicPackage

Still looking for other things to suit the theme, but nothing too outrageous.
