Settings -> Sound sets conflicting sample rates for Playback and Capture

[Endolith]

I've looked around but cannot figure out where this problem originates, but if I go into Ubuntu Settings -> Sound, and set both Output Device and Input Device to my USB Audio device, it starts showing a level meter, recording at 44100 Hz. If I then press the Test button for the Output Device, it plays at 48000 Hz:

~> cat /proc/asound/card1/pcm0p/sub0/hw_params
access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 44100
buffer_size: 88200

~> cat /proc/asound/card1/pcm0c/sub0/hw_params
access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 44100
buffer_size: 88200

My hardware cannot handle different input and output sample rates at the same time. It should pick one or the other and use it for both. macOS always uses the same sample rate for the entire device, for instance.
