USB Audio device no longer usable after reboot

My AlmaLinux9 server has been running great for months, playing audio through a USB device which was detected during installation. After a recent reboot I can no longer play audio because my app reports no sounds cards. dmesg shows detection of my sound card: [ 2.035043] usb 3-1.2.2: new full-speed USB device number 4 using xhci_hcd [ 2.102248] usb 2-2.1: new full-speed USB device number 4 using uhci_hcd [ 2.169381] usb 3-1.2.2: New USB device found, idVendor=08bb, idProduct=2902, bcdDevice= 1.00 [ 2.169389] usb 3-1.2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2.169394] usb 3-1.2.2: Product: USB Audio CODEC [ 2.169399] usb 3-1.2.2: Manufacturer: Burr-Brown from TI [ 2.174145] input: Burr-Brown from TI USB Audio CODEC as /devices/pci0000:00/0000:00:17.0/0000:13:00.0/usb3/3-1/3-1.2/3-1.2.2/3-1.2.2:1.3/0003:08BB:2902.0002/input/input6 [ 2.225293] hid-generic 0003:08BB:2902.0002: input,hidraw1: USB HID v1.00 Device [Burr-Brown from TI USB Audio CODEC ] on usb-0000:13:00.0-1.2.2/input3 Yet Linux doesn't see this as a sound card: aplay -l aplay: device_list:274: no soundcards found... What happened? And how do I fix this?
