Hi all,
I'm trying to use Ubuntu Mate 20.04.3 on the Raspberry Pi 4 with 4 GB RAM. I'm totally blind so rely on the Orca screen reader. When I flash the image to the SD card and boot it, all I hear is a buzzing sound when pressing Windows+Alt+s to enable the screen reader. What's causing this and is there any way to fix it? Is there something wrong with the audio support or is this an issue with Orca itself? If it's an Orca issue, can this be fixed in the image?
