Thanks for your help. But it doesn't work.<br>If the problem is caused by the module-null-sink. From the attachment,  We can see that, the module-null-sink was loaded,but can not found any data for key:sink:auto_null in the database. And I have tried to remove the module-null-sink from the default.pa, then the SIGBUS will no longer appeared,  other error will appeared.<br><br>ÔÚ 2016-02-27 18:41:45£¬bugzilla-daemon@freedesktop.org Ð´µÀ£º<br> <blockquote id="isReplyContent" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">

        <pre>What do you mean when you say you ported pulseaudio to arm? Pulseaudio should
work on arm out-of-the-box.

After reading up on what SIGBUS might indicate, one possible cause for this
crash might be unaligned memory access. This will make alignment issues to
become invisible (with performance cost):

    echo 2 &gt; /proc/cpu/alignment

Does that command appear to "fix" this crash? I hope it does, but in any case,
switch the alignment configuration back to 5 (or whatever was the original
value) and get a backtrace with gdb of the crash. A backtrace is needed for
further debugging.

You can read more about the kernel's alignment error handling configuration
here: <a href="https://www.kernel.org/doc/Documentation/arm/mem_alignment">https://www.kernel.org/doc/Documentation/arm/mem_alignment</a></pre>

Thans for your mail.<br>I have tried to modify the "enable-shm" and "shm-size-bytes", but it seems itdoesn't work. It also show that "Using shared memory pool with 1024 slots of size 64.0 KiB each, total size is 64.0 MiB, maximum usable slot size is 65496".<br><br>ÔÚ 2016-03-01 17:30:20£¬bugzilla-daemon@freedesktop.org Ð´µÀ£º<br> <blockquote id="isReplyContent" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">

        <pre>The crash seems to happen when accessing memory pool memory, probably when that
happens for the first time. For some reason the operating system doesn't like
that. The problem probably goes away if you set "enable-shm = no" in
/etc/pulse/daemon.conf. If the system is very tight on memory, you could also
try playing with "shm-size-bytes" in daemon.conf to set it to some lower value
than the default, although my (limited) understanding is that lack of memory
shouldn't be the problem if the crash happens already on the first access to
the shared memory. If the system has memory overcommit disabled, allocating the
memory pool should fail in an earlier phase, and if overcommit is enabled, this
code shouldn't fail, because it only consumes the first 64 kB from the memory
pool, which surely can't cause the memory to run out (otherwise you'd have
bigger problems).</pre>

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 Ð´µÀ£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>
