    Question error : “using null output device none available”

    Hi,
    I compiled a streaming client developed by QT in Ubuntu 12.04
    I can watch videos without audio
    However, when I want to play a video containing audio, I get this message in the terminal : “using null output device none available”

    I should mention that the first distribution I installed in my pc was ubuntu 10.04 and I was unable to play any sound in it.
    However after upgrading to ubuntu 12.04, this problem was resolved automatically and I haven't met any problem with sound playing.

    Could you please help me ?
    Thank you
