I purchased a ReSpeaker 2-Mics Pi Hat because I wanted to try out the voice recognition projects like Mycroft but I can’t get it to work. I’ve tried it on a Zero W, 3B, 3B+ and 4, followed the installation instructions on the Seeed site but I get the same results - it’s not seen by the software:

`$ aplay -l`  
` ****List of PLAYBACK Hardware Devices**** `  
`card 0: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones]`  
`Subdevices: 8/8`  
`Subdevice #0: subdevice #0`  
`Subdevice #1: subdevice #1`  
`Subdevice #2: subdevice #2`  
`Subdevice #3: subdevice #3`  
`Subdevice #4: subdevice #4`  
`Subdevice #5: subdevice #5`  
`Subdevice #6: subdevice #6`  
`Subdevice #7: subdevice #7`

Any suggestions on what else I can try?

Thanks

Steve

Firstly have you enabled the I2C and SPI interfaces in Raspi-Config?  
I don’t have one of these HATs, but I understand the header connector needs soldering, it might be worth checking for bad joints. If you are in any doubt post a picture of the soldering and someone will be able to point out potential problems.

Yes. From what I’ve read it only needs I2C but I’ve tried both on all the boards I’ve tried.

It comes pre-soldered.

OK that’s all the easy fixes checked, I’m out of ideas :)  
That being said I did see this: [https://forum.seeedstudio.com/t/respeaker-2-mic-wont-install-on-rpi0w/253313](https://forum.seeedstudio.com/t/respeaker-2-mic-wont-install-on-rpi0w/253313) this suggests there maybe some issues with compatibility if you’ve updated the Pi to latest kernel ( I know that issue is about installing, but I’m making a giant leap that updating the pi after installing the software may still have issues!).  
Unless anybody else has any suggestions I’d say contact support ( [https://shop.pimoroni.com/pages/contact-us](https://shop.pimoroni.com/pages/contact-us) ) and see what they say. We don’t see many of the Pimoroni crew on the forums these days, so that is probably the quickest way to get help.
