>Thanks for your help. But it doesn't work. 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.

        <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
