Hi Alexander,<br> <br> As adviced by you, I have uncommented "cpu-limit=no" in daemon.conf file but still the same problem occurs. <br><br>Regards,<br>Abdul Moiz <br><br> <div class="gmail_quote">On Mon, Jul 25, 2011 at 8:51 PM, Alexander E.

I think that omap4 is just<br> not powerful enough to do echo cancellation in software, and I guess<br> that's why your pulseaudio deamon is getting killed for running over the<br> CPU time limit.<br> <br> Could you try to verify this theory by uncommenting the "cpu-limit = no"<br> line in daemon.conf? This will lock up your omap4 board, though, if I<br> guessed the reason correctly.<br> <br> --<br> <font color="#888888">Alexander E.
