what is the default device ( hw , plughw or dsnoop ) and your sound card

different sound cards support different capture rate/ playback rate

how the voice audio is transfer through the network (resampled to lower rate
and mono or S16 to U8 to minimize network traffic ) this affect the latency and
the quality 

if your usb mic only support 16000Hz, and playback to your teammate's sound
card which use 44100Hz 


look at winealsa.drv/dscapture.c

start capturing only need snd_pcm_start() 

why does it need play_looping and CommitAll() ?

Try run those compilance test

WINETEST_INTERACTIVE=1 dsound_test caputre
WINETEST_INTERACTIVE=1 dsound_test duplex
