Summary:                    startup fails with libspeex.so.1.2.0
Description: 
I'm upgrading from 1.6.1.18 to 1.6.2.6. configure, make, make menuselect,
and make install all work without error. I've rm'd
/usr/lib/asterisk/modules. On startup 1.6.2.6 (and 1.6.2.7-rc2) hangs
here:

    -- CODEC SPEEX: Setting preprocessor Dereverb Level to 0.300000
  == Registered translator 'speextolin' from format speex to slin, cost 1


I can asterisk -r, but it's just hung. You can't even shut it down:

CLI> core stop now
No such command 'core stop now'

Deselecting speex func and codec in menuselect makes it work.

Well I didn't do that,but I now know what is the problem.

codecs.conf for speex:

the deadlock will occur if preproccessing is set to true AND pp_vad is set
to true.

This works with 1.6.2.7-rc3:
 
;enable preprocessor [true / false]
; allows dsp functionality below but incurs CPU overhead
preprocess => true

; preproc voice activity detection [true / false]
; more advanced equivalent of DTX, based on voice frequencies
pp_vad => false

I've no clue why pp_vad  worked with 1.16.1.17, but not 1.6.2.7-rc3. In
any event, I suggest pp_vad be hard-wired to false.
