    Hi,
    I know that some topics have already been created about this subject but
    nothing could help me...
    I was trying the c version of pocketSphinx for a long time using my one sound
    capture code using alsa.
    But I've just discovered that ad objects do what i was trying to do. So I came
    back to the alsa problem (i've never successfull used
    pocketsphinx_continuous=>always no micro founded...

    My speech processing was working but i now need to use the pocketsphinx
    framework to record sound.

    I've tried to use the hw:0,0 audio device but i 've got the Failed to set PCM
    device to mono: Invalid argumen

    So i've tried to use plughw:0,0 => Warning: Could not find Mic element

    So i finally tried to create a .asoundrc configuration file in my home
    directory, containing 

    pcm.plug0 = {
  type= plug;
  slave= {
    pcm= "hw:0,0";
  },
};

    Error returned: 

    ALSA lib control.c:882:(snd_ctl_open_noupdate) Invalid CTL 0
Mixer attach to 0 failed: No such file or directory

    When i trie this new device in audacity, with one channel, it's working, as
    when i'm using hw:0,0 in audacity in mono...

    I'm quite disapointed because i'was looking for a solution all afternoon...and
    it's still not working...

    Thanks for your answer!

    Mehdi
