sdrangelove pulse audio issues

[Aaron]

I'm trying to find out if pulseaudio is working with sdrangelove, I'm
using a USRP and can see all the graph outputs. However I can't hear any
audio output from received signals.

Is there anyway to debug the audio output? I tired to change the
following in:

sdrangelove/sdrbase/audio/audiooutput.cpp

line 54 format.setCodec("audio/pcm");

to the following:
format.setCodec("audio/pulse");
format.setCodec("pulse");
format.setCodec("default");
