Try to leave the rate default or 44100, some windows drivers can't resample

Try to leave the rate default or 44100, some windows drivers can't resample

it does not work, test with follow codes:

import sounddevice as sd
sd.default.device[0] = 1
fs = 44100 # Hz
length = 5 # s
recording = sd.rec(frames=fs * length, samplerate=fs, blocking=True, channels=1)
from scipy.io import wavfile
wavfile.write('recording.wav', fs, recording)

[nshmyrev]

Maybe it wants two channels or wrong device id. It is not really Vosk issue, you have just problem recording audio.

this is a bug of sounddevice , set utf8 coding in windows, it will met the errors; unset utf8 coding in windows,it will met UnicodeDecodeError:utf-8 error. above error may happen in some pc, not all windows pc met those error.
