Pipewire 1.0.7/Wireplumber 0.5.2 - No Audio Detected on Input with USB DAC Microphone

I cannot for the life of me resolve an input/source issue I'm experiencing. **Expected Behavior** When using: Digital Input (S/PDIF) - SteelSeries Alias Pro OR Analog Input - SteelSeries Alias Pro I am able to use the XLR Microphone connected to the DAC/USB Device. Note - Both inputs worked previously. I understand the SteelSeries Alias Pro is a USB DAC, I do not use it for Audio Output, Audio Input only. I know the XLR Microphone is 'receiving' me, as there is a light indicator that indicates sound is being picked up over the XLR. **Reality Now** When selecting an Audio Input (Source), I can still select either S/PDIF or Analog for the Alias Pro - there is a momentary 'activity' detected, but that doesn't seem indicative of anything at all. Tapping on the mic, talking into the mic, et. all produces no 'activity' detection. I have tried using a headset microphone in the interim, though interestingly that comes out way too quietly even at max volume.. (I have not tried boosting to 150%, just up to 100%). The headset in question is a SteelSeries Arctis Nova Pro Wireless. **Troubleshooting Information** lsb_release -a
