Hi,
fresh Rocky user here (previously Fedora and Centos), have an issue which i couldn’t find a solution for. I have a Behringer U-Phoria UM2 USB sound card which uses a common chip “Texas Instruments PCM2902”. The problem i have is that the system detects it not as an audio device but as a keyboard input and as a result i have no sound on my fresh Rocky Desktop machine. Below is an excerpt from /var/log/messages. I tried finding similar issues and few had issues with trackpad identified as keyboard or not being detected at all but i am puzzled on this one and i don’t know where to look for help.
