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. ```auto Oct 31 22:52:34 localhost kernel: usb 1-2.3: new full-speed USB device number 7 using xhci_hcd Oct 31 22:52:34 localhost kernel: usb 1-2.3: New USB device found, idVendor=08bb, idProduct=2902, bcdDevice= 1.00 Oct 31 22:52:34 localhost kernel: usb 1-2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Oct 31 22:52:34 localhost kernel: usb 1-2.3: Product: USB Audio CODEC Oct 31 22:52:34 localhost kernel: usb 1-2.3: Manufacturer: Burr-Brown from TI Oct 31 22:52:34 localhost kernel: input: Burr-Brown from TI USB Audio CODEC as /devices/pci0000:00/0000:00:01.2/0000:02:00.0/usb1/1-2/1-2.3/1-2.3:1.3/0003:08BB:2902.000A/input/input13 Oct 31 22:52:34 localhost kernel: hid-generic 0003:08BB:2902.000A: input,hidraw1: USB HID v1.00 Device [Burr-Brown from TI USB Audio CODEC] on usb-0000:02:00.0-2.3/input3 Oct 31 22:52:34 localhost mtp-probe[3885]: checking bus 1, device 7: "/sys/devices/pci0000:00/0000:00:01.2/0000:02:00.0/usb1/1-2/1-2.3" Oct 31 22:52:34 localhost mtp-probe[3885]: bus: 1, device: 7 was not an MTP device Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) config/udev: Adding input device Burr-Brown from TI USB Audio CODEC (/dev/input/event2) Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Burr-Brown from TI USB Audio CODEC : Applying InputClass "evdev keyboard catchall" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Burr-Brown from TI USB Audio CODEC : Applying InputClass "libinput keyboard catchall" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Burr-Brown from TI USB Audio CODEC : Applying InputClass "system-keyboard" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) Using input driver 'libinput' for 'Burr-Brown from TI USB Audio CODEC ' Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) systemd-logind: got fd for /dev/input/event2 13:66 fd 55 paused 0 Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Burr-Brown from TI USB Audio CODEC : always reports core events Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Option "Device" "/dev/input/event2" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Option "_source" "server/udev" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) event2 - Burr-Brown from TI USB Audio CODEC : is tagged by udev as: Keyboard Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) event2 - Burr-Brown from TI USB Audio CODEC : device is a keyboard Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) event2 - Burr-Brown from TI USB Audio CODEC : device removed Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Option "config_info" "udev:/sys/devices/pci0000:00/0000:00:01.2/0000:02:00.0/usb1/1-2/1-2.3/1-2.3:1.3/0003:08BB:2902.000A/input/input13/event2" Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) XINPUT: Adding extended input device "Burr-Brown from TI USB Audio CODEC " (type: KEYBOARD, id 13) Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (**) Option "xkb_layout" "au" Oct 31 22:52:34 localhost mtp-probe[3892]: checking bus 1, device 7: "/sys/devices/pci0000:00/0000:00:01.2/0000:02:00.0/usb1/1-2/1-2.3" Oct 31 22:52:34 localhost mtp-probe[3892]: bus: 1, device: 7 was not an MTP device Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) event2 - Burr-Brown from TI USB Audio CODEC : is tagged by udev as: Keyboard Oct 31 22:52:34 localhost /usr/libexec/gdm-x-session[2660]: (II) event2 - Burr-Brown from TI USB Audio CODEC : device is a keyboard ``` thanks for any help you can provide.
