Hello, Alex!

The record.py script at https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Using_the_AudioMoth_USB_Microphone_Firmware_and_Hardware/record.py is not running. I have tried to fix it with no results. This is the error I get:

Expression 'paInvalidSampleRate' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2048

Expression 'PaAlsaStreamComponent_InitialConfigure( &self->capture, inParams, self->primeBuffers, hwParamsCapture, &realSr )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2718

Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2842

Traceback (most recent call last):

File "/home/pi/record.py", line 29, in <module>

stream = audio.open(format=audio_format, rate=sample_rate, channels=number_of_channels, input_device_index=device_index, input=True, frames_per_buffer=chunk_size)

self._stream = pa.open(**arguments)

OSError: [Errno -9997] Invalid sample rate

Could you have a look? Any advice is appreciated!

Thanks!

Antonio.
