ALSA errors & Thread Errors

[bzmar]

Quick Question,

I'm running the demo.py with a personal.pdml. I was able to remove some of the errors by commenting out some lines in alsa.conf in the /use/share/alsa. However, there are three different types of errors I am getting:

When it works on first run I get: ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa connect(2) call to /tmp/jack-1000/default/jack_0 failed (err=No such file or directory) attempt to connect to server failed Listening... Press Ctrl+C to exit

Then after first run it will crash with these errors: ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'cards.bcm2835.pcm.front.0:CARD=0' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:5007:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM front ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa connect(2) call to /tmp/jack-1000/default/jack_0 failed (err=No such file or directory) attempt to connect to server failed Expression 'paTimedOut' failed in 'src/os/unix/pa_unix_util.c', line: 387 Expression 'PaUnixThread_New( &stream->thread, &CallbackThreadFunc, stream, 1., stream->rtSched )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2998 Expression 'pthread_join( self->thread, &pret )' failed in 'src/os/unix/pa_unix_util.c', line: 441

After crashing I get these errors: ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa ALSA lib confmisc.c:1281:(snd_func_refer) Unable to find definition 'defaults.bluealsa.device' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4996:(snd_config_expand) Args evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM bluealsa connect(2) call to /tmp/jack-1000/default/jack_0 failed (err=No such file or directory) attempt to connect to server failed Traceback (most recent call last): File "demo.py", line 27, in detector = snowboydecoder.HotwordDetector(model, sensitivity=0.5) File "/home/pi/rpi-arm-raspbian-8.0-1.1.1/snowboydecoder.py", line 126, in init stream_callback=audio_callback) File "/usr/lib/python2.7/dist-packages/pyaudio.py", line 750, in open stream = Stream(self, *args, kwargs) File "/usr/lib/python2.7/dist-packages/pyaudio.py", line 441, in init self._stream = pa.open(arguments) IOError: [Errno -9996] Invalid input device (no default output device)

Anyone aware of fixes for the thread issue?

Exactly the same for me.

Snowboy is running for first error.

Those were all ALSA errors, not from Snowboy.

Sometimes, when you see errors under When it works on first run I get:, Snowboy is actually working.

But your last error IOError: [Errno -9996] Invalid input device (no default output device) either means your microphone is not available, or means your microphone does not support 16K sampling rate.

Make sure rec -r 16000 -c 1 -b 16 -e signed-integer -t wav test.wav works on your device.

I have same problem, I used this one: rec -r 16000 -c 1 -b 16 -e signed-integer -t wav test.wav

and it works... Im getting this errors while i try to run : python demo.py ~/snowboy2/resources/models/snowboy.umdl

Errors:

python demo.py ~/snowboy2/resources/models/snowboy.umdl Traceback (most recent call last): File "demo.py", line 27, in <module> detector = snowboydecoder.HotwordDetector(model, sensitivity=0.5) File "/home/pi/snowboy2/examples/Python/snowboydecoder.py", line 139, in __init__ stream_callback=audio_callback) File "/home/pi/.local/lib/python2.7/site-packages/pyaudio.py", line 750, in open stream = Stream(self, *args, **kwargs) File "/home/pi/.local/lib/python2.7/site-packages/pyaudio.py", line 441, in __init__ self._stream = pa.open(**arguments) IOError: [Errno -9996] Invalid input device (no default output device)

@jabbadabbadahat yeah,the same error as yours,Do you solve this error now? thanks

[Techieali]

i am also getting a similar error, but i am able to detect my hot word after that thrown error IOError: [Errno -9997] Invalid sample rate

[Techieali]

is there any fix for this
