I have the respeaker 4 hat on a raspberry pi 3b+ with the newest raspbian image.
I have carefully followed the instruction on Seeeds forum page (as linked from the the product page). I have the leds workings with pixels_demo.py, and can record with arecord and play back with aplay.
However kws_doa.py does not work (from the 4mics_hat library)
(env) pi@pistt:~/4mics_hat $ python kws_doa.py
[‘arecord’, ‘-t’, ‘raw’, ‘-f’, ‘S16_LE’, ‘-c’, ‘4’, ‘-r’, ‘16000’, ‘-D’, ‘default’, ‘-q’]
arecord: main:788: audio open error: No such file or directory
I have tried other options but nothing seems capable of listening to the 4 mic hat for input correctly for speech recognition.
Typing arecord -L yields
(env) pi@pistt:~/4mics_hat $ arecord -L
Discard all samples (playback) or generate zero samples (capture)
Default Audio Device
Direct sample mixing device
Direct sample snooping device
Direct hardware device without any conversions
Hardware device with all software conversions
Is there something wrong with the setup?
I have spent some 6 or 7 hours trying to get ANYTHING to respond to voice in any way without any result. I am tearing my hair out - any one any help???
This hat seems not only a bad design (does NOT sit on the pi without running fowl of the of the camera connector) but the instructions simply do not work. This is not usually the type of software support you get with products from pimoroni.
