The point is whether those USB audio device can pass the ds3d test in windows
or using oss driver

it is not easy to find a buffer size which fit all sound cards , some of the
sound card may just use a buffer size which is near 0.5 second as the current
implementation specify for a buffer time of 0.5 seconds.

as dsound has a default sampling rate , 

wine may use snd_pcm_hw_params_set_buffer_size_near(pcm , hw_params ,0.5
seconds x default sampling rate ) .

but you still need to set period or set_period_size which still depend on sound
card
