The following command line also does not produce sound:

csound -+rtaudio=pa_bl -iadc -odac --env:CSNOSTOP=yes /Users/rsholmes/Desktop/test.csd

This is the command line generated by CsoundQt's "Run in Term". I don't see pa_bl in the documentation for -+rtaudio at https://csound.github.io/docs/manual/CommandFlagsCategory.html#FlagsCatMinusPlusRtaudio ; I tried -+rtaudio=CoreAudio as well, and again got no sound.

So it appears NOT to be a CsoundQt issue.

Terminal output pasted below.

This may be a/the reason - output amp is around the dither level. Maybe 
set 0dbfs= 1 in the orch header, then reduce amp a little bit to avoid 
clipping.

According to your output sound was indeed produced, at an amplitude of
1.2. Try setting -0dbfs to 2.
