<pre>Based on the line numbers, I figured out that segment_attach() fails.
segment_attach() can fail for two reasons, and the first one shouldn't be
possible (the pa_hashmap_size(i->segments) >= PA_MEMIMPORT_SEGMENTS_MAX check
can't fail, because this is the first segment that we're handling).
So, pa_shm_attach() fails. That function has several failure cases, but all but
two of them log an error message. There are no error messages from
pa_shm_attach() in the log, so the problem is that shm_open() fails, and errno
is either EACCES or ENOENT. That is, either pactl doesn't have permission to
access the shm file, or the shm file doesn't exist.
What does "ls -l /dev/shm" print?</pre>
