Re: JACKD audio

[Fabien PELLET]

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.
