Fix timing issue

I don't know why I missed that

1) of course we have to check tv_sec, not tv_nsec
2) when we do a nanosleep, but use the "now"-val for the lastsent-
   time, we obviously keep the wrong time.
   This leads to the program thinking more time elapsed than really
   has, leading to less nanosleep and thus higher playback-speed.

Now this is fixed, and apart from state-transition issues,
call-receiving now works perfectly. ;)
