OVRLipSyncMicInput Causes Huge Performance Hit When Started on Quest

Hi, I'm trying to capture microphone input from my Quest microphone using the OVRLipSyncMicInput component.  I find that whenever the application loses focus or pauses I get a huge performance spike in my profiler coming from OVRLipSyncMicInput.  It seems that whenever the mic starts or stops it's just a huge computational drain and I'm wondering if it's causing problems with my app.

Is anyone else experiencing anything similar?  Thanks!
