[ecasound] Possible bug: setpos does nothing after 'c-select noexist'

Hi Kai and all,

With ecasound v2.7.1+dev:

-- short summary --

ecasound -c -a 1 -i test.wav -o alsa-default

> t
(engine starts)
> getpos
4.44
> c-select noexist
> setpos 0
> getpos
8.88

-- actual debug output with -ddd -- (skip to <<< for relevant lines)
