[1:19:50][Closing remarks]
[1:20:28][Q&A][:speech]
[1:21:13][Are you setup to use ASI Sound Drivers?]
[1:22:05][Is your audio pointer code calculating independently of the variable-fixed visual frames per second?]
[1:24:35][What sort of problems can high audio latency introduce?]
[1:27:18][Could you use that anonymous union struct trick to access the members of bitmap info header structure more easily?]
[1:28:47][Question about switching Audio APIs]
[1:31:42][Why are we ignoring write cursor?]
[1:33:10][Would splitting related functionality in separate files help?]
[1:34:10][If we use the play cursor as offset, could we not overwrite previously written audio data?]
[1:39:37][Comments about Audio APIs again]
[1:40:14][Would rendering at 60 FPS help with the audio latency?]
[1:41:16][Could you change latency values?]
[1:41:33][Is it possible that OBS is affecting the audio latency?]
