Record sound

[Lousy Fisherman]

After a pacman -Syu on January 8th I am now able to record at 16K with alsa.
arecord -f dat -r 16000

However accessing the microphone at 16K through python still fails. Using the speech_recognition library, I create a Microphone and a Recognizer.

import speech_recognition as sr

mic = sr.Microphone()

r = sr.Recognizer()

with mic as source:

    audio = r.listen(source)

When listening to the Microphone with the Recognizer I get the following:

Expression 'alsa_snd_pcm_poll_descriptors_revents(...params...)' failed in src/hostapi/alsa/pa_linux_alsa.c, line: 3654

Expression 'PaAlsaStreamComponent_EndPolling(...params...)' failed in src/hostapi/alsa/pa_linux_alsa.c, line: 3871
Expression 'PaAlsaStream_WaitForFrames(...params...)' failed in src/hostapi/alsa/pa_linux_alsa.c, line: 4418

This happens in site-packages/speech_recognition/__init__.py line 161 in read() and line 652 in Recognizer.listen()

    buffer = source.stream.read(source, CHUNK)

and the actual python line which fails is in site-packages/pyaudio.py line 608

    pa.read_stream(...params...)

At this point I think the Microphone is not being initialized properly from pyaudio, Endianness perhaps?

Any nuggets of wisdom will be greatly appreciated
