 Which threads have you read? Link them here for reference. You apparently use pulseaudio, which you do not mention. What simple python script is that? Does is take any arguments? Do you have pulseaudio-alsa installed?

arecord -lL;
lspci -vvnn | grep -A1 '040[1-3]'; cat /proc/asound/modules; amixer;
lsusb #if there is a usb sound card;
# or use the alsa-info script

Re: Problem with jack

Ok thanks

import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:                # use the default microphone as the audio source
    audio = r.listen(source)                   # listen for the first phrase and extract it into audio data

try:
    print("You said " + r.recognize(audio))    # recognize speech using Google Speech Recognition
except LookupError:                            # speech is unintelligible
    print("Could not understand audio")
