[SOLVED] No audio with PipeWire on DAC after full system upgrade

Audio was working fine but after a full system upgrade and a reboot, no sound would play to the DAC I wanted. Previously, I would select the output device and profiles through pavucontrol.  This time when I tried doing that, Off was the only profile available on the DAC.

M4 is the DAC I'm referring to.

$ cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xb4428000 irq 141
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xb4000000 irq 17
 2 [M4             ]: USB-Audio - M4
                      MOTU M4 at usb-0000:00:14.0-3.3, high speed
 3 [Microphone     ]: USB-Audio - Logitech USB Microphone
                      Logitech Logitech USB Microphone at usb-0000:00:14.0-3.4, full speed

$ cat /proc/asound/pcm
