Hi there
My problem: when i try to load a patch with the command "pd-extended -nogui -open /home/pi/test.pd" the console send me a message saying "ALSA input error (snd_pcm_open): Device or resource busy" and "ALSA output error (snd_pcm_open): Device or resource busy"
But, when I use the command "pd-extended -open /home/pi/test.pd"(without -nogui) everything works fine.
Note: the error "ALSA input error (snd_pcm_open): Device or resource busy" and "ALSA output error (snd_pcm_open): Device or resource busy" also occurs when I choose the default audio card of the Raspberry PI but not when I choose a generic USB audio card all this with GUI of course.
System: Raspberry PI with 2013-12-20-wheezy-raspbian
I appreciate any ideas. Thanks.
