Can you show us an example of how you're doing this? Playback and Record aren't async so you'll need to show us how you're doing this. Also don't hijack threads you hit replay on the one "Re: [Freeswitch- users] FreeSwitch setup as a "Dumb" SBC" as the subject, deleted the subject and started a new body. That hijacks the thread and that can cause your problem to go ignored in some cases if people aren't interested in the thread topic depending on how their reader threads the emails. Please click new message and type freeswitch- users@lists.freeswitch.org in and then input your subject and body to start a new thread.

Hi,
I was trying to record a background music with a user's voice at the same time. I did a playback and started recording. But the recorded user's voice and the background music is about 0.5 second out of sync. I also tried to use uuid_displace instead of playback, but I got the same result.
