Bug Report Microphone out of sync

Hello. At start video sound and video have sync, but after one minutes microphone sound after a minute of sound desynchronizes and delay increases to 5-10 seconds. In earlier versions I haven't this problem - microphone worked synchronously. But I do not remember which version it started.

I tried check "Force desktop audio to use video timestamps as a base for autdio time" and "Mic Sync Fix Hack", as suggested on the forum, but it does not help. I tried different combinations of these options.

If I select "Use Mic QPC timestamps" sound is 9-10 seconds and then disappears. In log file many strings like a "08:11:26: Audio timestamp for device 'Line in at rear panel (Blue) (Realtek High Definition Audio)' was behind target timestamp by 38! Had to delete audio segment."

What can I do with thas?

Make sure your Scene Buffer time is at least 700 (or increase the value until it stops cutting out), and try the Mic QPC timestamps again.

Yes, my mistake. I tried it and more than the buffer, the longer the sound is to turn off with errors in log. Buffering time changed from 400 to 2000 with step 100. Make it even more?

And a question - what options in Advanced -> Audio must be set? Only QPC timestamps? "Force audio to video timestamps" and "Sync Fix Hack" must be off?

SOLVED: Microphone out of sync

Okay, I'm solve my issue. On Settings -> Advanced -> Audio I check "QPC timestamps" and uncheck two other options. Work perfect with Settings -> Advanced -> Scene Buffering Time 6000ms.

Thank you, Dodgepong and I'm sorry - I didn't read "Known bugs and Issues" before open this topic.
