I don't know if it is gentoo or alsa specific, and if it can be related to
your problem, but it was maybe 2 weeks ago, I experimented a strange problem
after a kernel update and the in-kernel alsa driver. It was impossible to get
sound from one of my sound card. All was working, the other cards was working,
but it was just no sound at all with my audiofile (the second card in my
config).
The only cure I found was to stop the alsa daemon,
remove /var/lib/alsa/asound.state and restart alsa.
After that, the sound was working again with this card.
