I haven't tried CsoundAV yet. With Csound 4.23f12 (under GNU/Linux) the 
error message is the following (note that this is the same reported by 
Matt Ingalls on 2002's message I cited):

         instr   1

expecting y, line 6:

Early return from csoundPerform().

Here is the code I used:

<CsoundSynthesizer>
<CsOptions>
-odac -iadc
</CsOptions>
<CsInstruments>

nchnls	= 1

	instr 1
ain	in 				; live source
fin	pvsanal	  ain,1024,256,2048,0	; analyse, using Hamming
fout  	pvsmaska  fin,1,0.75           ; apply eq from f-table
aout    pvsynth   fout                 ; and resynthesize
	out aout
	endin
</CsInstruments>
