steam record audio is out of sync by a sec or 2

[Killen4glory]

my record settings or high at 240 min. i trimmed and saved a clip earlier today no issues. and the next one has a 1 or 2 sec audio delay

try going into your audio settings and turning up the bitrate of your output device

I have the same issue but mine gets way worse over time, by the end of my Dota 2 match today the audio was delayed by over 30 seconds. I have theories but I don't know for sure yet what could be causing it. The possibilities I could think of:
1 - alt+tabbing adding a small delay every time you do it
2 - an issue with multi-monitor setups
3 - an issue GPU hardware encoding
4 - raw recordings folder being on a HDD instead of SSD
