I doubled check that my Sound Blaster card supports 24 bit, and I alse
see it in my devices (pacmd list-sinks), but running this in python
failed with:

Expression 'PaAlsaStreamComponent_FinishConfigure( &self->capture,
hwParamsCapture, inParams, self->primeBuffers, realSr, inputLatency )' failed
in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2731
Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters,
sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode
)' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2843
