There is no time stamp handling. It is just TX'ing in advance and
synchronous to received RX rate.

8b9277615d Neu structure for the paging process (B-Netz) 
Paging tones are not created within sound_alsa.c
The audio API is now responsible to switch to paging channel.
In case of SDR, the sdr.c will switch frequency offset.
