Vítor, I believe Maarten and/or Andrew will end up integrating a winepulse
driver into Wine.  So far for PA's promise to integrate with ALSA. :-(
Still, no crackling from winepulse 1.3.24 does not prove that the 10ms write
mmdevapi scenario in place since 1.3.25 will work without trouble.

>render.c:1217: Test failed: Position delta 12960 not regular
Looking at your pre-restart logs from comment #21, it appears that it's not
snd_pcm_delay which is at fault, rather than PA which is already in broken
state:
 2.178:trace:alsa:alsa_write_data XRun state avail -32, recovering [10x]
At each underrun, all frames written so far are consumed, which makes it look
like GetPosition advances too fast, whereas you probably heard nothing at all
from the speakers.

>so that wine directly accesses alsa
Can you use the registry since 1.4-rc4? "plug:dmix" might work. Either it'll
block all sounds from PA or PA will sit in dmix' back, without improvement.
You can also use plughw:0 via winecfg, blocking PA from access.

BTW, I've submitted PA bug reports

Let's hope for the best.
