I am receiving error messages every time I play a sound with PyAudio and am having trouble supressing them.

ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
I have tried the solution from PyAudio working, but spits out error messages each time but I keep getting an error message saying
OSError: libasound.so: cannot open shared object file: No such file or directory
I have tried changing it to libasound.so.2
but then it freezes the program when trying to play a sound instead of doing anything.
I am including my source code for how I am using PyAudio. The alsaMessageSuppress
function is called in the initialization of the class.
def alsaMessageSuppress(self):
ERROR_HANDLER_FUNC = CFUNCTYPE(None, c_char_p, c_int, c_char_p, c_int, c_char_p)
def py_error_handler(filename, line, function, err, fmt):
print 'Debug Message Suppressed'
c_error_handler = ERROR_HANDLER_FUNC(py_error_handler)
asound = cdll.LoadLibrary('libasound.so.2')
# Set error handler
asound.snd_lib_error_set_handler(c_error_handler)
def soundThread(self, sound):
p = pyaudio.PyAudio()
duplicated_sound = wave.open(StringIO.StringIO(self.loaded_sounds[sound]), 'rb')
def callback(in_data, frame_count, time_info, status):
data = duplicated_sound.readframes(frame_count)
return (data, pyaudio.paContinue)
stream = p.open(format=p.get_format_from_width(duplicated_sound.getsampwidth()),
channels=duplicated_sound.getnchannels(),
rate=duplicated_sound.getframerate(),
output=True,
stream_callback=callback)
while stream.is_active():
sleep(.1)
stream.stop_stream()
stream.close()
#print "%s Finished" % sound
p.terminate()
duplicated_sound = None
