If the R-Pi guys are being responsive, I wonder if you find any answer about the SPI interface for the Mesa boards?  I found that linux-cnc reported SPI errors when trying to talk to the 7C81.  I'm new to the Linux-CNC community, so maybe I'm doing something else wrong.  But I got the idea on the forums that there was some known issues with SPI on the R-Pi5. It's been on my list to follow the build instructions and see if I could find out more, but that hasn't happened yet.

    Thanks,

Upstream have resolved the rpi-imager compatibility issue.
Their sound guy is away for  a few days but has it on his to do list.
The willingness to sort this out has been amazing

I have to find time to merge the changes and rebuild it. I Am flat out for
a while.

The regular raspbian OS comes with sound via HDMI. I am toying around
with packages to install to see if I am getting anywhere without much
configuration. KDE works after installing task-kde-desktop - no
sound, though.
Install the pavucontrol package.  That hass the controls you need to
move the sound between ports.

Thank you for that pointer, I checked and found it installed but it
does not find any input or output devices.

Best,
