Hi Fabien,
we've got https://wiki.gnuradio.org/index.php?title=Audio_Sink
If you want to use jack, you'd go into your ~/.gnuradio/config and set
[audio]
audio_module=jack
Best regards,
Marcus

Hello,
My signal is in the range +/-1. As I use the audio output of my RPI, it seems that the
problem is here : playing a wave file outside gnuradio produce the same issue.
However, is there a tutorial somewhere or a manual that explain the syntax that can be
written in the "device name" of the audio_sink or audio_source ?
Thanks,
Fabien, F4CTZ.

Sounds like you’re overloading the audio sink. Have you tried lowering the amplitude of
the sine wave?
If you have a speaker hooked up to the output I’d imagine you can discern that pretty
quickly with your ears.
You’ve said what you’re not getting on the O-scope, but what are you getting?

Hello,
Does someone manage to make work GNURadio with JACKD2 ?
I get the gr_sink inside the graph of qjackctl, I get signal on the output. For the
test I only send a sinwave at 1KHz to the audio_sink but on the physical output, using
an oscilloscope, I have something with the right amplitude but it is absolutly not a
sinwave.
Is there a tutorial or a documentation on how to config GNUradio well with this audio
server ?
The goal is to reduce the latencies of a flowgraph.
