Comment (by rmstonecipher@…):

 Mihai,[[br]]
 Rather than making a default variant that everyone but you would use, I
 would prefer to switch the backend to something other than pulse; however,
 I would advise against CoreAudio.  Despite being native, CoreAudio has
 been a real pain in the neck when another project lacked dedicated OS X
 coders to keep up with changes in CoreAudio's syntax.  Assuming libao is
 available, would you find it to be an acceptable solution?[[br]][[br]]
