I’m using a Raspberry Pi B+ running jessie with OF v0.9.8.
I’ve compiled a project with ofMaxim to test some basic audio playback which works fine on Mac OS. The program compiles fine but during runtime I have some errors relating to RtApiAlsa. The error ends with
[ error ] RtApiAlsa::probeDeviceOpen: pcm device (hw:0,0) won't open for input..
I’ve seen others with some similar issues, this thread had a solution to a similar issue but didn’t resolve it for me [solved] RPi + sound synthesis.
I’ve been attempting to get audio playback either from the HDMI port or the audio jack but both don’t output audio. I went through the steps on the Alsa project page and testing it with
aplay -D default test.wav did work but still no joy with the OF program running.
Has anyone got a solution for this?
Here is the full error:
