Hey,
I tried to install a ReSpeaker2 v1 on my RPI3B+ with the following guide:
wiki.seeedstudio

Sadly at Step 3. I get an error:
arecord -D “plughw:2,0” -f S16_LE -r 16000 -d 5 -t wav test.wav
Recording WAVE ‘test.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
arecord: set_params:1416: Unable to install hw params:

BUFFER_TIME: 500000
BUFFER_SIZE: 8000
BUFFER_BYTES: 16000
TICK_TIME: 0

I tried it with different repos now and with different how-tos but the result is always the same with this error.
Can someone please help me resolve this.

Thanks a lot in advance!

After many evenings at the computer and even more head-shaking, I have finally found a solution.
You have to use the HinTakt driver in v6.6.
You can retrieve it from GitHub with the following command:
git clone -b v6.6 --single-branch GitHub - HinTak/seeed-voicecard: This is an enhancement fork with the explicit aim of supporting current shipping Raspbian/Ubuntu kernels without requiring downgrading. Please donate at https://hintak.github.io/ if it works for you. Use vX.Y branch for kernel version vX.Y

Hi GuAnDi, can I ask which OS you were using? I’m having the same problem with the same device and Raspberry, but that solution didn’t work for me. Thanks!
