Hi,

i've recently setup OBS to record locally & sometimes stream live to facebook and have been having an audio drift issue. The audio drift is evident in the local recording as well as the streamed copy.

Setup is:

Blackmagic Design Intensity Shuttle Thunderbolt - Video & Audio for channel 1
Yamaha USB audio interface - Audio channel 2

Video is 1080i50 from the shuttle (this is because I am feeding
In the log I can see it's adding audio buffering:

20:20:25.519: adding 42 milliseconds of audio buffering, total audio buffering is now 128 milliseconds
20:34:25.527: adding 21 milliseconds of audio buffering, total audio buffering is now 149 milliseconds
20:41:18.335: adding 42 milliseconds of audio buffering, total audio buffering is now 192 milliseconds
20:55:09.079: adding 21 milliseconds of audio buffering, total audio buffering is now 213 milliseconds
21:02:03.798: adding 21 milliseconds of audio buffering, total audio buffering is now 234 milliseconds

I've also tried setting "use buffering" to off but the audio still drifts.

any advice/help is appreciated.
