maxChans failed

Hi there,

I'm trying to get your soundmeter working on a Raspberry Pi Zero W.

I'm getting the following error when I try do anything:

Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1514
Expression 'ValidateParameters( inputParameters, hostApi, StreamDirection_In )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2818
Traceback (most recent call last):

stream = Stream(self, *args, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/pyaudio.py", line 441, in init
self._stream = pa.open(**arguments)
IOError: [Errno -9998] Invalid number of channels

I have no experience with Python, so not sure what I'm looking at here.

Same issue on my side, Raspberry Pi 3B+ with an usb mic

@Blyzz616 This is solved in #1 (you need to create a config with a channel = 1
