I just wanted to close the loop. I was finally able to correct this problem by reinstalling the Mac OS on my system, and then reinstalling Minecraft. Sounds are working fine, now. Thanks for your help!

Here's the Game Output (definitely a problem with the sound: "Could not open ALC device"):

I just tried adding some resource packs to see if that would break the logjam. I installed/selected the BDcraft Sounds Pack 1.1 - still no sounds - and I installed/selected TARDIS Model and SFX v1.10 and again no sounds, and also no texture changes!
