I ended up solving this. After changing to ALC_ALL_DEVICES_SPECIFIER all 
was working except I wasn't hearing any sounds playing. It turns out I 
had a line of code for 3D sounds that was setting a strange volume, 
which probably just made the sound so I couldn't hear it. After I fixed 
that all was working.  Thanks for your input.
