I doubt it. First, ALSA have notion of the default device,
which Wine should respect. On the other hand, using the
hw:n device relies on a hardware mixer for sharing the sound
card, which some widespread integrated cards don't have. So
a lot of users would prefer using plughw:n (or another
dmixed device) instead. The ALSA default can be set in
~/.asoundrc or by environmental variables, which is very
convenient. Wine shouldn't behave differently unless
explicitly configured so.

Probably not at the moment (except for /proc/asound/cards
etc.) It was discussed on the ALSA devel list recently, but
I don't remember the conclusions.
