I think your processor is way too slow to encode this resolution to VP9 in realtime. That probably leads to skipping frames (in the long run), and as a side effect possibly breaking audio. VP9 encoding is known to be quite slow. You need to choose a lower resolution, faster encoding parameters, or even a different codec. Have you tested with "-c:v libx264 -preset ultrafast", to see whether the resulting video+audio is fine? (It needs to encode at speed >= 1.0 or fps >= 25 then of course, but I'm quite optimistic that it can.)
