v2 Mic Array device not found

Products & Technology ReSpeaker
#1

I have a problem with selecting Respeaker 2 Mic Array as the recording device.



Raspberry PI 3

Distributor ID: Raspbian GNU/Linux 9

Release: 9.0

Codename: stretch



I plugged the Mic Array into the USB port of the RP and don’t see the device in arecord -l or lsusb. How do I resolve this?

#2

I have the same problem, that the 6 Mic array does not even blink with some LED and of course it cannot be detected by debian.

Even after the installation of drivers (described here) done.

@admin, @ESP, Support does not react on my emails.

#3

I am trying to reach the support till 2 Weeks and got back just the ignorance.

The MicrophoneArray is now just the useless peace of hardware that does not work.

What should I do?



I am not a foreign man in a linux world, but I can’t get this thing work.

What do the other people, who don’t know linux?



Unfortunately no LED on the ReSpeaker is on and it cannot be detected by aplay/arecord.

I checked the 1-wire settings (it was off) and I restarted anyway again the raspi.



Still no effect.

Hi there,



it seems the driver is not installed correctly. please try to reinstall the driver again. Please post the installation log to us.



You also can change the source location by editing /etc/apt/sources.list, select your nearest source.



For the 6 mics pi hat, please also check the 1-wire setting, Please click raspberry -> Preferences -> Raspberry Pi Configuration, then select the Interfaces tab, make sure the 1-Wire is Disabled. thanks.
