If you have PA installed you may have noticed alsamixer, among other things, is now broken. This is because someone thought it was clever to make media-sound/pulseaudio[alsa] depend on media-plugins/alsa-plugins[pulseaudio] unconditionally. What this dependency does is install a bunch of plugins not actually required for PA to use ALSA, and drops a few turds in /usr/share/alsa/ that takes away access to your actual sound card.

Gentoo isn't GNOME OS, so here's some shell script to make it go away and, more importantly, stay away:
Code:
(
    cd /usr/share/alsa/alsa.conf.d/
    for i in *pulse*.conf; do : > $i; done
    chmod a-w *pulse*.conf
    chattr +i *pulse*.conf
)

Alsamixer works fine for me with PA. Do you have PA 2.*?

I'm using ~amd64. Every update for the past few months has broken things so that I have to manually tell alsamixer to control the card.
