Maybe not finding the proper microphone?

The USB PnP Sound Device is the one I'm using, a tiny plugin microphone: https://www.amazon.com/gp/product/B00IR8R7WQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Any thoughts?

Same here.

EDIT --- It seems this is related to pyaudio and not directly to the voicecontrol module. I found this snippet of code:

import pyaudio
p = pyaudio.PyAudio()
   for i in range(p.get_device_count()):
     dev = p.get_device_info_by_index(i)
     print((i,dev['name'],dev['maxInputChannels']))_

When running the above code, it produces similar errors as shown below, but also gives me this output text:

(0, u'bcm2835 ALSA: - (hw:0,0)', 0L)
(1, u'bcm2835 ALSA: IEC958/HDMI (hw:0,1)', 0L)
(2, u'sysdefault', 0L)
(3, u'front', 0L)
(4, u'dmix', 0L)
(5, u'default', 0L)

Not sure where to go from here.

I'm having similar problems, but not exactly the same. Mine starts with the following:

ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround51.0:CARD=0' ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4738:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM surround21 ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.surround51.0:CARD=0' .....

My microphone and speaker do work. If I type "arecord -f dat -D plughw:1,0 test.wav" -- I can speak into my mic and it will record. "play test.wav" plays the file perfectly.

https://github.com/Kitt-AI/snowboy/issues/45 The same problem, means that there is problem with sampling rate and mic configuration

[Sispheor]

Hi, same problem for us here.

[xdker]

我也是这个问题

Same problem with c++ demo.
