Pretty much all DACs run at 48Khz by default due to operating systems picking it as a sane default.

Pipewire will quite happily pipe through audio without resampling if it is the only source on a system. You can see this by running pw-top and using speaker-test with various sample rates.

Even if it reports 44.1 it resamples internally to 48 in all hardware I've seen.
