Playing audio with gr-ha5kfu if Audio Sink fails

Nov 1, 2015

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.
