Description of Problem: 

Emacspeak becomes "partially functional" when launched without sox 
installed on MacOS.  Happens with both mac and swiftmac servers. 

The core issue is when hitting error lines in the emacspeak-sounds.el 
file, it partially breaks emacspeak in such a way that certain things like
explicit reads still work, but most things (changing lines, all the sort of 
basic stuff), stop working.  Confirmed with logging, isn't just a server 
failure, emacspeak isn't sending it.

This is BTW, the same exact behavior John C had. 

I traced this issue (trace below) and found that it is due to a comparison 
of two nils (play-program and pactl) which runs an error line and that 
is when emacspeak becomes only partially functional. 

The fix is easy enough, just make sure that it doesn't emit that error when 
both 
are nil, as both being nil doesn't mean they match in a useful way. 

Note: the exact comparison that causes this issue is in the file 3 times, but 
I 
only encountered it at the place mentioned in the trace below. 

Below is my emacs information and a trace.
