Audio Out of Sync Bug (VEGAS Pro 21.0 - January 2024)

So I've begun to notice recently that my audio starts to go out of sync, replay random parts and not match up to its audio track visualizers at all. I tried restarting VEGAS, restarting my computer and updating my computer but it doesn't solve anything. When I reopen it, it shows where the audio actually is, but then after multiple frames the audio goes out of sync again and randomly cutting to a different part. This is really annoying and I can't use VEGAS pro to edit my videos because of this. I haven't found anyone talking about it anywhere so, whoever is reading this, please help!

@john_dennis @RogerS Thank you for the clarification, and I apologize for being too emotional (I had limited time, just one setup with Vegas Pro 21 and the unique source material, which I basically couldn't record again). So I tried to find an explanation in my hardware or the latest Vegas Pro 21 update (build 315). I have used Vegas for many years, and I honestly haven't tried MKV files before, only MP4. Seems like their support in Vegas Pro was always limited. I'll follow the tutorial https://www.vegascreativesoftware.info/us/forum/faq-what-obs-studio-settings-work-well-with-vegas-pro--109925/ and next time will record from OBS properly. ShutterEncoder is a powerful tool, thanks. I'm used to ffmpeg command line, though sometimes it's faster to have some GUI on top.

By the way, I've found a way to use AMD HW decoder again. In OBS there is a "Keyframe Interval" value set to 0 (auto) by default. I tried using 1s or 2s, then the video playback works just fine in Vegas on AMD HW Decoder (File I/O section). In combination with MP4 container instead of MKV, I can work with output recordings from OBS Studio without any issue.
