with "gx" enabled, I could still capture 5.1 when playing a file through WMP (and it could play in 5.1).
with "gx" disabled, SDL_Audio couldn't create a 5.1 output
with "right click and test" from control panel, with or without gx enabled, could capture.
Maybe it's an openSDL bug? :)
should still report it to ASUS though...in 5.1 with GX enabled, it does not capture wave's played by ffplay (even stereo).
= the need for "true" =
"C:\Programs\VLC TEST 1.1.10\vlc.exe" -vvv dshow:// --sout=#transcode{venc=ffmpeg,vcodec=mp2v,vb=10000,fps=30,scale=0.5,width=1280,acodec=mp3,ab=192,channels=2,samplerate=44100,soverlay}:std{access=http,mux=ts,dst=:8081} --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-keep :dshow-vdev=screen-capture-recorder :dshow-adev=virtual-audio-capturer :dshow-caching=0
I think play it with VLC, or with mplayer, and/or substitute VAC with it, see what happens.
check for "tearing" and out of sync audio...

Changing back to High Performance Power Plan is a workaround to fix it, but consumes a lot more energy and produces more heat.
subtracting at beginning didn't help it...
adding "sleeps"
resulted in this message very fast:

threaded:
with 5 other threads, dual core, they both seem to start giving bad feedback, possibly single threaded with smaller sizes [?]
with high prioritied single thread: 4480, some big though...seems as good as single thread maybe...
seemed that it avoided discontinuity messages even if "lots" of them were running at once [!]
unless one had to pause to delete a file, then it could get it.
