I get following error when I try to run Sample Google AI as in Configure and Run the sample -
(env) pi@raspberrypi:~ $ python -m googlesamples.assistant
Traceback (most recent call last):

raise PortAudioError(msg)
sounddevice.PortAudioError: Error initializing PortAudio: Unanticipated host API -10000 error 0: ''
Not sure if this is related. But, I also have a arecord issue-
(env) pi@raspberrypi:~ $ sudo arecord --format=S16_LE --duration=5 --rate=16k --file-type=raw out.raw
arecord: main:722: audio open error: No such file or directory
Audio output testing as described in Google AI setup guide works. Also, I have completed steps 2 to 4 described in link. It does not fix the error though.
This command works -
(env) pi@raspberrypi:~ $ sudo arecord --format=S16_LE --duration=5 --rate=16k -D hw:1,0 --file-type=raw out.raw
Recording raw data 'out.raw' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
Warning: rate is not accurate (requested = 16000Hz, got = 44100Hz)
please, try the plug plugin
Is there a solution to get this going?
Thanks.
change ~/.asoundrc to below
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hw:0,0"
}
capture.pcm {
type plug
slave.pcm "hw:1,0"
}
}
