Dear Georg, Thanks for reply, As you have suggested. I have updated the pulseaudio to the later version which is after pulseaudio-10.0 (i.e., pulseaudio-11.1). We have found that the delay is still exists after playing any music upto 12hrs. We found like the audio and video are completely out of sync with a delay of 4-5 seconds. In the change log between pulseaudio-11.1 and pulseaudio-12.2, i haven't seen any updates regarding latency. I hope that the latency will also be exist in pulseaudio-12.2 also. Thanks, Harish Gaddameedi.
