How to connect ReSpeaker Mic Array v2.0 to Ubuntu

I’m trying to have the Ubuntu 18.04 system recognize the microphone array when connected via USB, but it doesn’t even recognize it.



I followed the instructions shown by the following wiki



and the way that it was advertised, one could simply plug and get it running. However, when trying to connect it to my Ubuntu 18.04, the computer doesn’t even recognize the microphone.



I’ve seen that when other people plug it in and run the command below, they obtain the following results

<br/> $ arecord -l<br/> <br/> **** List of CAPTURE Hardware Devices ****<br/> card 0: PCH [HDA Intel PCH], device 0: AD198x Analog [AD198x Analog]<br/> Subdevices: 0/2<br/> Subdevice #0: subdevice #0<br/> Subdevice #1: subdevice #1<br/> card 1: ArrayUAC10 [ReSpeaker 4 Mic Array (UAC1.0)], device 0: USB Audio [USB Audio]<br/> Subdevices: 0/1<br/> Subdevice #0: subdevice #0<br/> card 2: Device [PrimeSense Device], device 0: USB Audio [USB Audio]<br/> Subdevices: 1/1<br/> Subdevice #0: subdevice #0<br/> card 3: Phone [MT65xx Android Phone], device 0: USB Audio [USB Audio]<br/> Subdevices: 0/1<br/> Subdevice #0: subdevice #0<br/>



However, when I run it, I obtain the following results

<br/> $ arecord -l <br/> <br/> **** List of CAPTURE Hardware Devices ****<br/> card 0: PCH [HDA Intel PCH], device 0: ALC298 Analog [ALC298 Analog]<br/> Subdevices: 1/1<br/> Subdevice #0: subdevice #0<br/>



This tells me that the microphone array is not being recognized. When I try to see the USB devices, I obtain:


<br/> $ lsusb <br/> <br/> Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub<br/> Bus 001 Device 005: ID 138a:0097 Validity Sensors, Inc. <br/> Bus 001 Device 003: ID 04f2:b5ab Chicony Electronics Co., Ltd <br/> Bus 001 Device 008: ID 046d:c52b Logitech, Inc.

What have I tried



I have tried playing around with the ALSA Mixer, and nothing was recognized

I have tried the Gnome System Settings, and nothing was recognized

By following the link above, I followed the instructions by cloning the repo usb_4_mic_array and tried to do a Device Firmware Update by running

$ python dfu.py --download 6_channels_firmware.bin



and it said that No DFU is found



I have tried using the following repo

https://github.com/respeaker/mic_array_dfu



and it returned


<br/> VID = 0x1d6b, PID = 0x3, BCDDevice: 0x500<br/> VID = 0x138a, PID = 0x97, BCDDevice: 0x164<br/> VID = 0x4f2, PID = 0xb5ab, BCDDevice: 0x10<br/> VID = 0x46d, PID = 0xc52b, BCDDevice: 0x2407<br/> VID = 0x8087, PID = 0xa2b, BCDDevice: 0x10<br/> VID = 0x1d6b, PID = 0x2, BCDDevice: 0x500<br/> Could not find/open device<br/>



Verdict



There are people who have gotten it to work



Most people are using it for RPi, but I am more interested in getting it to work on my local machine, and I think this is a system problem, and I have no idea how to proceed.



Thank you in advance!
