If I install with Debian 10 installation media, then change the /etc/apt/sources.list everything works as it should, my sound card is correctly detected, and I have screen reader during installation, I have screen reader when booting into Debian and I can use the MATE Graphical Environment as my user. Perfect.
I can also upgrade to Debian 11 by changing my /etc/apt/sources.list files.
But unfortunately for me the Debian 11.0 and current Debian 11.1 installation media just don't work for me. Every previous version since Woody in 2002 has worked just fine.
Best wishes,
David
