ULTRA++ installation guide

Hi,
I’ve followed the guide as-is in the top post

At this step:speaker-test -l5 -c2 -t wav

i get

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -19,No such device

I have reinstalled per the next step

cd WM8960-Audio-HAT
sudo ./uninstall.sh
sudo ./install.sh

I am using a pi zero 2 w, with ultra++ hat, installed on Raspberry Pi OS Lite per rhasspy docs.

I note some conflicting advice in some of the comments about outdated drivers, and can see the top post was updated back in april. Do I need to be using a different driver? I want the headphones out and onboard microphones for this project.

Lastly: > `cd WM8960-Audio-HAT

sudo ./uninstall.sh
sudo ./install.sh`

in the guide should this not be cd ultra2? I don’t have a WM8960xxx directory that I could see.
