I have updated the installation guide of the ULTRA and the git with some alsa presets:
update your git:
git clone GitHub - RASPIAUDIO/WM8960-Audio-HAT: The drivers of [WM8960 Audio HAT] for Raspberry Pi
cd WM8960-Audio-HAT
in your case try this one, type:
alsactl --file preset_external_jack_microphone_input2 restore
then I did a:
sudo arecord -f cd -Dhw:0 | aplay -Dhw:0
to play on my headphones what is recorded, you might have to adjust the device number ‘0’ if you have other devices installed.
