Problems under ubuntu #18

Curious if pulseaudio works on your pc and if it makes a difference. |
|
volkan@ubuntu:~/Belgeler/quietnet$ pulseaudio I think yes :/ |
|
@wakeup did you install pyaudio using apt-get or from the pyaudio site? |
|
Give these instructions a try, if they work I'll add that as a note in the readme. |
|
I installed using apt-get and tried your instructions, but unfortunately it is the same issue. |
The underun is likely caused because pulseaudio is already accessing the card - you can pause it using http://linux.die.net/man/1/pasuspender. In general to avoid such deadlock, you need a soundserver like jackd https://help.ubuntu.com/community/What%20is%20JACK, but you already figured this out from the following log entries in your trace ;-) (apt-get install jackd)
You need to change "pcm.front cards.pcm.front" to "pcm.front cards.pcm.default" in /usr/share/alsa/alsa.conf. The rest of the errors are not meaningful, for instance, "bt_audio_service_open: connect() failed: Connection refused (111)" refers to your bluetooth device - you are likely missing some bluethooth packages, but you can simply ignore it. This should get you moving forward and debug further. |

@Katee @alouche , Thanks for your suggestion. 👍 I started jackd(via qjackctl) which when started suspends pulseaudio (pasuspender -- /usr/bin/jackd). But I get the following errors.
whereas If I stop jackd(via qjackctl) it throws this error quietnet (master)$ python send.py Any pointers would be of good help. My System Info quietnet (master)$ uname -a quietnet (master)$ aplay -l **** List of CAPTURE Hardware Devices **** quietnet (master)$ aplay -L quietnet (master)$ arecord -L |

You need to make sure real time and memory lock are enabled for jackd
Then make sure your username is added to the group "audio".
should display

I have Ubuntu 12.04.3 and I started jackd by qjackctl. (note, the package to reconfigure on Ubuntu 12.04 is jackd2, not jackd) listen.py: send.py: at this point send.py hangs irresponsible to sigint, and i have to sigkill it. without using jackd: at this point send.py also becomes irresponsible to sigint. |
|
... It works now, after I put my laptop to standby and woke it up again. |
|
Even if I try to change the priority to the real-time for some reason I always see it to be 0 and not 95 quietnet# dpkg-reconfigure -p high jackd2 and so do I get the following error #python listen.py Quietnet listening at 19100HzALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear quietnet# python send.py |
|
Kubuntu 14.10x64: |
|
Is there a way to hide these messages?? |
|
@xeffect : Did you figure out what was going on as far as the priorities are concerned? I'm having trouble running the example script from PyAudio Website (Wire (Callback)). |
|
use following tips for solve bt_audio_service_open: connect() failed: Connection refused (111) after that,it still have follow errors, but it doesn't matter. I can listen and say, but i still want to solve it, hope you help me! thank you for you tips again. |
|
code--- r = sr.Recognizer() try: output: |
|
I am getting error at root@xion:/home/xion/pyaudio# python microphone_recognition.py |
|
this started when i crashed the program myself... some soc file is locked it looks like dont know were to look |
|
Did someone find an answer to it. |
|
Maybe this could help (don't forget to reboot and kill pulse as mentioned): https://github.com/Uberi/speech_recognition#user-content-on-ubuntudebian-i-get-errors-like-jack-server-is-not-running-or-cannot-be-started-or-cannot-lock-down--byte-memory-area-cannot-allocate-memory |
will u please help i also changed "pcm.front cards.pcm.front" to "pcm.front cards.pcm.default" in /usr/share/alsa/alsa.conf. |
I think everything is normal until this:

Welcome to quietnet. Use ctrl-c to exit
But when I send something, i receive the following:
ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred
As a result, nothing comes in listening part. What can be the problem?
