What I did was the following: First, I sent the playback command: call-command: execute execute-app-name: playback execute-app-arg: <filename> Then I send uuid_record (Sorry, it was not Record command): api uuid_record <uuid> start <filename> 120 I also tried replacing the playback command with: api uuid_displace <uuid> start <filename> 0 mux But the end results are the same. The recorded user's voice is about 0.5 second behind the expected result.

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.
