>> The test results must appear together with the traces.
Please ensure you get both into the log. Your newest one only contains test
results, no trace from WINEDEBUG=+xyz.
rm render.log; ENV=XY E=mc2 program args >>render.log 2>&1
Also, please set MIME-type text/plain manually on text attachments if your
browser can't do it right.

I'm confused.  When is it stuttering, when not?
Please try to be as precise as possible.

What do you mean by default?  I'm referring to a log trace like this:
>AUDDRV_GetAudioEndpoint "default" 0x124928 0 0x32fb38
which shows that the ALSA device named "default" was opened.  This is not
necessarily the same as mmdevapi's default device, or winmm device #0.


>render.c:1210: padding 24000 position 36096/48000 slept 750ms iteration 3
>render.c:1244: data at (nil) (small 0)
>render.c:1246: Test failed: NULL buffer returned
Here the trace is important to figure out how exactly this device claimed to
have a full buffer during 100ms.
