I say sorry in advance for being snarky in the next few sentences, but...
Recently quite a few hacks were removed from MPlayer's ALSA code, probably
assuming that ALSA might finally be working properly...
I'd suggest to try different versions of ao_alsa by doing
svn up -r123 libao2/ao_alsa.c
where you replace 123 by e.g.

Unless broken by the WORDS_BIGENDIAN -> HAVE_BIGENDIAN change, that last
one is from May, so should be working at least if that's what caused the issue...
Personally I suspect r29549 to be the cause.
