Seeed ReSpeaker 4-Mic Array for Raspberry Pi

At first I got the lights to work, but no audio. The "tech support" says use Audacity to check the audio. Audacity seemed to confirm that the audio was not recording, but there are no further instructions on how to fix it. To get further help you must join the forum and raise the issue, or see if someone in the forum has fixed the issue. After going through the whole install process again I discovered that my GPIO expansion board was the issue. I was using the expansion board so that I could get power out to my speaker board and the input from the 3.5mm jack, as per the setup instructions. Now that it is connected directly to the Pi4 it works, and the sound comes out of the HDMI monitor, so no need for the speaker board! It is a bit odd calling it Snowboy and then getting a female voice replying!!

Brilliant bit of kit for audio and audio detection

Easy to set up, I have the mic and sample LED scripts working. The audio quality and recording volume are not up to scratch. Expect a high level of noise and also expect to shout at it even from 1m away to get reasonable audio recording volume. Worst of all, none of the sample code is commented, so although I understand programming functions, variables etc, I don't know what any of the existing code actually does. Even with a lot of trial and error over several hours of experimentation, results seem random and don't seem to correlate with the obvious assumption as to what the code is supposed to do. I've posted a couple of times on the manufactures forum, but over 5 days have been totally ignored, I've seen many others in the same situation. Using it also disables HDMI audio, something that I feel could have been avoided with a slight amount of extra effort from the Devs could have been avoided. But when they can't be bothered to comment their own sample code, on a hobbiest piece of kit which the user is going to want to tinker with it, what more would you expect?
