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.
