Thank you for your patience. It finally worked.
I’m using the git installation indicated in the our tutorial “ultra2” the seeeds studion one does not seem to work.
You were right I stupidly used the method indicated on GitHub - RASPIAUDIO/ultra2: 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.
git clone GitHub - respeaker/seeed-voicecard: 2 Mic Hat, 4 Mic Array, 6-Mic Circular Array Kit, and 4-Mic Linear Array Kit for Raspberry Pi
cd seeed-voicecard
sudo ./install.sh
sudo reboot
Instead of:
git clone https://github.com/RASPIAUDIO/ultra2
cd ultra2
sudo ./install.sh
sudo reboot
Certainly because of the excitment of receiving the card and wanting to try it…
I had to access my Pi zero remotely via VNC because I always run my Pis headless, install Audacity and followed your procedure.
But now it works. One last thing, it seems I can’t completely mute the built in 2 microphones although I set db gain for LINPUT1 & RINPUT1 to 0 in alsamixer… If I unplug the trs mic I can still record sounds… How can I completely disable the built in microphones when I use the trs mic?
Thank you.
