Hi, i have installed mycroft on a raspberry but as linux not by burning the sd card.
Y have conected an USB microphone and its path is
I have tried changing the /.asoundrc to this:
pcm.!default {
type asym
capture.pcm “mic”
playback.pcm “speaker”
}
pcm.mic {
type plug
slave {
pcm “hw:1,0”
}
}
pcm.speaker {
type plug
slave {
pcm “hw:0,0”
}
}
I have seen this path by running:
pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

Subdevices: 1/1
Subdevice #0: subdevice #0

The audio works perfect in audacity.
arecord -D plughw:1,0 test.wav --> works perfect
arecord test.wav --> doesn’t work
Maybe is that I cant set up the default Microphone.

Thank you so much for reading.

Ok, it’s much better to use the Picroft image file normally. If your RPi is used for other services you can reinstall them after Picroft has been installed. Do you know the audio troubleshooting page: Audio-Troubleshooting.
