I would try enabling resampling in CamillaDSP and set the sample rate to whatever you generate your biquads at. I think it should be setup such that it just changes the capture rate but then resamples to your specified playback rate but I am not sure how the specific rate switching implementation works.
I just setup a RPi4 with Moode today, I can play around with it tonight and try to see what it is doing.

The configuration below works with SuperPlayer 1.0.1 (Jesper Lykke's porting of CamillaDSP to raspberry pi 4/piCorePlayer 8):
samplerate: XXXX
chunksize: <<chunk_size>>
capture_samplerate: <<sample_rate>>
enable_resampling: true
resampler_type: Synchronous
where XXXX is the fixed samplerate (e.g. 192000) you want to obtain for the output data stream.
Synchronous resampler works for any sorurce/destination sample rates commonly used in digital audio, i.e. 44100, 48000, 88200, 96000, 176400, 192000, 352800, 384000, ....
