Hi together,
i am using grc 3.7.6.1. The system is odroid with ubuntu 14. I tested
the alsa system with aplay and the sound works.
When i start my project on odroid i get the following error message. On
my desktop pc with grc 3.7.2.1 / ubuntu 14 the grc alsa works.
INFO: Audio sink arch: alsa
ERROR: [default]: snd_pcm_hw_params failed: Invalid argument
