Summary:                    [patch] audiohook: translation to slinear 8khz
regardless of samplerate
Description: 
If an audiohook is attached to a channel that uses a codec with a
samplerate of 16khz (e.g. G722) the frames are always downgraded to 8khz
16bit signed linear. So if we have 16khz G722 with 320 samples, that will
be downgraded to 160 samples.

The expected behaviour would be to translate the frames to 16khz 16bit
signed linear (SLINEAR16) with 320 samples.

---------------------------------------------------------------------- 
I'm afraid this won't be this easy.  I'm betting that there are lots of
applications that assume that the audiohook is always going to be providing
8khz audio.  Perhaps an option in the ast_audiohook_init() function to tell
what sample rate is expected would work.  Whatever it is, I think the
audiohook should be guaranteed to consistently provide the same sample rate
after initialization.
