Hi list,
on SD with a fresh Raspbian Stretch
RPI 3
installed pisound drivers and software throug the install-pisound.sh, at the end of installation that seems ok I receive this error:
Reading pisound serial failed, did the kernel module load successfully?
I post here some useful info and hope you can help fixing the problem
