Unfortunately that does not really help pinpoint the problem. It is likely a
race, but it could be anywhere. Without a stack trace of the freeze or a way
to reproduce the problem, there is nothing I, as a VLC developer, can do about
this bug report.
Changing volume (with ALSA) exhibits a noticeable delay of a few tenth of a
second, due to buffering in the ALSA driver. That is neither new and nor
fixable. Several seconds of delay is abnormal.

While a kernel bug cannot be completely ruled out, a bug in libpthread seems
more probable. With that in mind, it would be good to know if the bug
reproduces with *unoptimized* libpthread builds (on i386, this can be achieved
by removing the libc6-i686 package).
