souto93 commented 7 years ago

Hello everyone. I've been stuck with this for days... I'd appreciate any help , this is very frustating.

pi@raspberrypi:~/Downloads/AlexaPi $ sudo python main.py Checking Internet Connection... Connection OK Traceback (most recent call last): File "main.py", line 497, in start() File "main.py", line 397, in start inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, alsaaudio.PCM_NORMAL, device) alsaaudio.ALSAAudioError: Device or resource busy [plughw:CARD=Device,DEV=0]

This is what i get from arecord -L

I had this problem until I turned off the graphical desktop, with my Pi configured to boot just to the console (sudo raspi-config). Might not be practical for all but if you're building a headless voice activated system then having the GUI loaded is just a waste of resources.

Please switch over to the new project and if your issue persists there, file an issue in the new repo's issue tracker. Thank you.
