Hallo!
Since the last few days I am trying out Linux with Ubuntu 20.04.4 LTS for the first time. I have also installed FG 2020.3.12. But unfortunately I don't get sound in FG.
I have downloaded the AppImage-file and the txz-archive. The archive is unzipped and FG is launched via the AppImage-file.
I recognized that, if FG is launched in window mode, in the Ubuntu sound settings there is a "fgfs" slider and sound is heared. If I change to fullscreen mode, there is no sound and in the Ubuntu settings the "fgfs" slider is gone.
Ryzen 5 3600, RX 590, monitor via HDMI, monitor's speakers
Thank you in advance for your help.
