I’ve got continuous underruns and overruns, clicks with Audio Sink in GNU Radio, so I used the Execute External Process Sink in gr-ha5kfu, with
csdr, and the
mplayer command line tools.
I used the following command line:
csdr convert_f_i16 | mplayer -cache 1024 -quiet -rawaudio samplesize=2:channels=1:rate=48000 -demuxer rawaudio -
Now I’ve got smooth playback.
