Bug ID: 49699
           Summary: Red Dead Redemption 2 has crackling audio
           Product: Wine
           Version: 5.14
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winepulse.drv
          Assignee: wine-bugs@winehq.org
          Reporter: bshanks@codeweavers.com
      Distribution: ---
Red Dead Redemption 2 uses WASAPI for audio, and sometimes has crackly audio.
It asks for a very small buffer (10 ms) when calling
IAudioClient::Initialize(), and then has a thread which checks the buffer
padding every 2 ms. It waits until there's at least 256 frames free in the
buffer, and fills 256 frames at a time.
When using winepulse, it has a low latency path and provides a 10 ms buffer.
This is 440/480 frames, not leaving much slack when refills are only 256 at a
time.
As far as I can tell, Windows never gives out a buffer smaller than 20 ms
though. This is more around 1056 frames, leaving much more slack. Disabling the
winepulse low latency path results in a buffer around this size, and audio is
much better. winealsa also seems to do this by default, and it sounds fine.
