First (and at the moment, the only one) for me is BP-Gallery (www.buddydev.com) – it’s a premium plugin with lots of possibilities and it’s worth the money you have to pay for.
Another opportunity will be (in march, the developers say) BP-Media (Bp-Album+), you can find it here: http://code.google.com/p/buddypress-media/
At the moment the stable version doesn’t support Audio, but you can play around with the nightly build.

Greets!
