Question / Help Mic progressively un-syncs

Hi, so when streaming on twitch my AT2020 mic starts off perfectly synced with the game coming from my Elgato. However the longer I stream the more it becomes out of sync... Here is a log from a quick output file test :)

Well the elgato is delayed by 1500 milliseconds, do you have that set for your mic?
 
I have my elgato delayed 1500 milliseconds because the gamesound was out of sync before... my mic audio is delayed by about 1400-1600 (it varies for some reason) milliseconds to sync up off start. But after about 30 mins of streaming my audio un-syncs...

I would probably recommend avoiding using any buffering for the elgato.

Anyway, as for the mic, if the mic itself is having sync issues, there are two options in advanced for it (though don't try to use them both at the same time). "Use mic QPC timestamps", and "Mic Sync Fix Hack". Try them in that order.

If you use the "Use mic QPC timestamps" option, make sure to increase your scene buffering time to at least 700.

These options are admittedly a bandaid for an existing issue with the audio subsystem, but will be removed in the future after the audio subsystem has been rewritten
