[Discuss-gnuradio] ALSA Source

[Raman O]

Hello,

  I have acoustic modem which uses ALSA source as interface to outside world. I use a preamble based time synchronization technique to find start of data in the frame. But my synchronization method is taking too long and in the process i think i am loosing incoming samples from ALSA source.
Is there a way to buffer samples from ALSA source , until i finish synchronization.
Please provide me some suggestions.

Thanks in advance,
Ram
