Error on sounddevice for Radxa Zero

I get a weird error:
Expression 'r' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2097
Expression 'PaAlsaStreamComponent_FinishConfigure( &self->playback, hwParamsPlayback, outParams, self->primeBuffers, realSr, outputLatency )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2737
Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2842

Which based on my googling skills, is a result of portaudio + alsa. But I'm unable to make clear of the actual error. The error happens on this line

sd = sounddevice.OutputStream(device=AUDIO_DEVICE_ID, blocksize=512, samplerate=48000, channels=2, dtype='int16', callback=AudioCallback)

Device: Radxa Zero
OS: Ubuntu Focal

Any tips?
