Thanks for your mail.<br>I had download another audio file, it could be played by pacmd play-file cmd. May be the coding format of the audio file caused the issue.<br>But it could not be played by paplay cmd, it  looks like, paplay need to use shared memory, even If I set enable-shm to no.<br><br>Another question, if I just send pcm streams to pulseaudio to realize the audio play(the decoding has been done in another application). Where are the API that could be called.<br><br>ÔÚ 2016-03-03 16:14:14£¬bugzilla-daemon@freedesktop.org дµÀ£º<br> <blockquote id="isReplyContent" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">

        <pre>If paplay fails with error message "Failed to open audio file", it means that
libsndfile's function sf_open_fd() failed. Based on the available information,
it's impossible for me to say with any more precision what the problem is.</pre>
